The flowsheet was based on laboratory tests wherein troublesome factors were eliminatedahead of design and construction. The flowsheet provides for unit arrangement of equipment and for added flexibility. Two-stage closed circuit crushing (with an apron feeder for control to the jaw crusher), provides ore for grinding circuit. Crushed material is conveyed to a Screen and the oversize is returned to the secondary cone crusher. The screened fraction drops to a reversible conveyor, thence to fine ore bins.
Adjustable stroke belt ore feeders regulate the feed to two 5 x 10 Steel Head Ball Mills in closed circuit with Cross-flow Classifiers. Each classifier discharge flows by gravity to two banks of 6 Cell No. 18 Sp. Sub-A Flotation Machines. The grind, 65 mesh is held as coarse as possible to reduce grinding costs and still attain maximum recovery. Each flotation section provides six cells for roughing and three cleaning stages with provisions for elimination of one or more stages for cleaning when type of ore permits (flexibility incorporated in Sub-A Machines).
The flotation concentrates are pumped to a regrind circuit to produce desired final size meeting specifications. The final ground concentrates are thickened and filtered. Filters are directly above concentrate storage bins.
The mill site near the mine is accessible to water, power, labor and supplies, and includes adequate space for expansion and tailings disposal. The topography makes gravity flow through the mill possible and allows for delivery of ore direct from mine cars to mill.
Equipment selected gives simplicity and flexibility in operation and allows for changes in tonnages and character of ore. Due to class of labor available, complicated controls and adjustments were eliminated where possible. The machinery selected and installed permits duplication of units for expansion.
As field welding was not available, bolted steel ore bins were installed. The machinery foundations, building foundations, retaining walls and floors are concrete. The flotation machines are mounted on low piers to allow for drainage. An operating platform of wood was installed between flotation machines to give clear working space. The flotation machine launders were designed to permit changes in cleaning stages without shut-downs or prolonged delays, and permits circuit adaptation to changes in ore characteristics. A tailings thickener permits partial reclaiming of water, in dry seasons.
The correct design of a milling plant can mean its success or failure when in operation, the difference between profit and loss. Maximum metallurgical results with low operating and maintenance costs requires thorough study and sound planning. Selection of equipment and construction features must be balanced with available finances and a minimum sacrifice in operating efficiency. Here is a typical small plant where proper design resulted in a successful operation.
This 75-ton, lead-zinc-gold-silver mill was based on a flowsheet developed through batch and continuous laboratory tests. These studies showed single stage crushing and grinding to 65 % minus 65 mesh was adequate for this operation. Tests indicated that over 70% of the gold, 40% of the silver and 60% of the lead was recoverable in the grinding circuit. Therefore Unit Cell and a Mineral Jig section were installed. Adequate flotation capacity to selectively float the lead and zinc was provided, together with a small concentrating table to visually show results of flotation. The zinc and lead concentrates are pumped v direct to a 4-foot by 4-disc Filter with two compartments. This filter was placed on top of the concentrate bin which location provides desirable operating room around the filter and could be seen from almostanywhere in the mill. The concentrate bins were of laminated wood constructionsturdy and inexpensive. Filtered concentrates drop directly into the bins.
Thickeners were eliminated due to initial installation expense and extra housing required because of climate. Low dilution, by keeping sprays in flotation launders to a minimum and ability of Vertical Pump to handle frothy pulps makes this possible.
The mill site was selected several miles from the mine at a point where water, power and tailing disposal area were available, and where it was accessible even during the heavy snow season. The site is on a natural slope, permitting gravity flow in the mill with minimum pumping requirements.
Equipment is arranged as compactly as possible without crowding and without sacrifice of working space, in order to keep the mill building to minimum size. This keeps capital investment low, and reduces heating costs during cold weather. The mill building, of wood construction with laminated wood roof trusses with one-quarter pitch, was covered with insulating material and corrugated sheet material. This construction was most suitable due to the climate and
low cost of lumber in the area. A small steam boiler and unit heaters were installed for heating. Mill and crushing buildings are on concrete foundations extending about four feet below the ground line. Concrete floors of 4 to 6 thick are sloped per foot, permitting slushing down with a hose.
Crushed ore conveyor is enclosed in a conveyorway for weather protection. Fine ore bin is housed within the mill building to prevent freezing. An inclined belt feeder with variable speed drive gains elevation to grinding mill. Feeder was designed with sloping hopper to reduce load on the belt of feed discharging from the bin.
Foundation for Ball Mill was made of reinforced concrete and cast in one section to prevent distortion and misalignment due to possible settlement or shifting of the foundation. Ball mill, unit flotation cell, jig, and classifier were arranged for easy access and operation. The ball mill was equipped with a spiral discharge screen to remove oversize material ahead of unit cell and jig. The 30 spiral classifier was equipped with a rotating motor-driven paddle to remove troublesome wood chips from classifier overflow screen.
The two six-cell No. 18 (2828) Sub-A Flotation Machines were elevated on timber bents with operating platforms between the machines; this gave space belowmachines for pipe lines, launders and concentrate pumps. Reagent feeders were grouped together above flotation machines and conditioners at elevation of filter floor for gravity flow of reagents, and for accessibility.
The mill control office located in the center of the mill, was designed with large windows so almost every machine in the mill could be seen. Operating floors most frequently used were kept as nearly as possible on the same level to reduce stair climbing for the operators. Mill was designed so two men per shift could handle this plant very well.
A gallery was provided in the trussed-roof section, the length of the building, for the installation of main electrical circuits, safety switches, and magnetic motor controls. This kept most of the electrical items away from splash and dirt. All wiring was selected oversize to reduce voltage drop, giving higher operating efficiency and reduced electrical maintenance. Totally enclosed motors were used for reduced maintenance. Push button start-stop controls were placed at the machines and in the mill control office, so that any machine could be controlled from either place.
A typical problem confronting a mining operation of moderate production is how to design a mill at a reasonable cost incorporating modern equipment and essential basic principles of materials handling with the minimum construction and mill costs.
The first step in mill design is the flowsheet based on reliable ore tests. The mill capacity and equipment sizes as shown has been selected as an example for treating 500-550 short tons of ore per 24 hours per day. Two-stage grinding is to all minus 65 mesh for an average ore. Sufficient flotation capacity is included for a medium to slow floating ore. Thickening and filter capacity is selected for a 10 to 1 ratio of concentration as would be the case when treating a 3% copper ore with the copper mineral being chalcopyrite. In such case it would be necessary to filter 50 to 55 tons of concentrates each day. The use of a mineral jig or flotation unit cell in the grinding circuit is recommended. A simple test in our laboratory can tell you whether a coarse product can be recovered easily in the mill circuit.
The general design will apply to other ores with slight modification. The arrangement provides for ultimate use of gravity flow as is noted by the absence of pumps and elevators. The basic machines in plan and elevation are shown along with a flowsheet of the crushing,grinding and mill recovery circuits.
Mine run ore is fed to the primary jaw crusher by a heavy duty apron ore feeder over a grizzly. Crushed ore from the primary crusher is fed over a vibrating screen ahead of the cone crusher to remove fines. The crushing plant is normally designed to crush the entire daily mill tonnage in one shift or, at the most, 2 shifts.
Two- stage grinding provides the grinding economies outlinedin DECO Bulletin B2-B13. In the wet grinding circuit, a rod mill takes the entire feed at and reduces it to approximately 14 to 20 mesh. This mill is normally operated in open circuit with the classifier and ball mill. Usually there is a power saving with this grinding arrangement and often a substantial saving in the cost of the entire mill can be effected by reducing to a minimum some of the requirements in the crushing plant due to this method.
The ground ore overflows the classifier at -65 mesh and approximately 25% solids and is shown being conditioned ahead of flotation. Two parallel banks of Sub-A Flotation Machines on the same floor level are shown for roughing, scavenging, cleaning and recleaning. This arrangement in the flotation circuit provides maximum flexibility in the flow of material, high grade selective concentrates, and low final tailings.
Normally 10 square feet of thickener area is provided for each ton of concentrates per 24 hours which gives reserve capacity to accommodate normal filter maintenance without shutting down the flotation circuit.
In thedesign of any milling operation, continuity of flow should be given first consideration and all weak links eliminated. The old saying an hours delay means no profits today is even more important in our modern milling circuits where labor costs are high.

This 911MPE-PF842 is a complete, but still small miniature froth flotation plantis ideal for in-house pilot plant testing your mining project. Its layout is for a mono-metallic flowsheet (buy section for each additional metal). Its flotation cell agitators tip speed can be varied between 3 set-points. The froth paddles or scrapers also offer 2 rotation settings. As presented, this small laboratory float plant weighs 160 kilo and offers:
Assuming a 35% flotation density and a 2.8 SG to your test ore feeding this laboratory flotation pilot plant, you will have approximately 25 minutes of conditioning time with 15 minutes of rougher flotation time if operated at 13 kilos/hour (200 grams/minute).
When mining companies are confronted with the difficult decisions on advancing and exploration project to the feasibility and construction stages, it has always been their dream to know with greater certainty how various regions of the ore body will react in the milling and concentration processes. While band scale and test work is common and inexpensive, the results and information provided are somewhat limited due to the difficulty in accurately predicting the effects of recirculating streams or gradual changes in solution chemistry.
Conventional pilot plans provide the detailed engineering data required to develop a final process flow sheet. However, they are expensive to set up and operate and are only viable for larger projects that are well advanced. Associated with conventional pilot plans are the high-cost of sample acquisition due to the quantities that are required. The difficulty of obtaining samples representative of deposit in various ore types and the potentially high cost of sample disposal.
To address the limitations of the band scale test, and the high cost of the conventional pilot plant, 911metallurgist.com has developed an innovative solution, called the Mini Flotation Pilot Plant. The Mini Flotation Pilot Plant or MFPP produces the same type of engineering data as the conventional plant, but at a fraction of the operating costs, since the MFPP requires a relatively small amount of sample ore and minimal personnel to operate.
The Mini Flotation Pilot Plant permits flotation testing with continuous flows, similar to traditional pilot plants. But is designed to make use from samples obtained from exploration drilling campaigns. Modular in design, the heart of the MFPP is comprised of: the flotation module, the continuous regrind pin mill, the column flotation module and the reagent dispensing system which can have up to 16 precision chemical dosing pumps. The flotation module consists of 12 flotation cells, modelled after the standard Denver D12 laboratory cell and uses the same impeller and tank design. As well, each cell has individual level control. The products of each cell are moved to the next using peristaltic pumps.
Auxiliary components include the batch grinding mill; ergonomically designed to reduce material handling and turnaround time for grinding large samples, with a nominal capacity of up to 20kg per batch. The slurry holding tank, the Mini Flotation Pilot Plant feed tank and optional computer system for data logging and control. The scale of equipment handles feed ranges from 5-15 kilograms per hour. A high level of instrumentation is also included to permit digital logging of pilot plant data and replication of conditions from test to test.
With the Mini Flotation Pilot Plant, the ore can be subjected through the following treatment stages: grinding, rougher and scavenger flotation, regrinding of concentrate tailing streams, cleaning of reground product, scavenging of cleaner tailings, recleaning of the concentrate. Furthermore, the flexibility in arranging circuits in the MFPP means that various flow sheets can be tested. The merit of testing using either conventional Pilot Plant or Mini FlotationPilot Plant is that both these methods can test the process on a continuous basis, which is of major importance to the investor. When the two are compared, we start to see the differences. The MFPP allows for greater operational flexibility, allowing optimization for working conditions during execution.
Since the Mini Flotation Pilot Plant is designed to use samples obtained from exploration campaigns, different ore zones and blends of ore zones can be tested. The amount of ore required for testing is significantly less. For example, a conventional plant may require more than 15,000 kg of ore for a 5-day campaign. Compared to only 1,000 kg for a Mini Pilot Plant. The MFPP requires fewer personnel to run and operate, comparable to the less expensive Ben scale testing. And even though less ore is required for the Mini Flotation Pilot Plant, comparative tests performed on both methods show that the results obtained from the MFPP are comparable to that of the conventional Pilot Plant.
The Mini Flotation Pilot Plant has already been used successfully by, comparative tests performed on both methods show that the results obtained from the MFPP are comparable to that of the conventional Pilot Plant.
While providing data equivalent to conventional pilot plants, it allows mining companies to substantially reduce cost by eliminating the expenses associated with acquisition of large bulk samples, reduced time to make decisions by simplifying sample acquisition, reduce risk by having the ability to do more testing to assess or variability through using a variety of samples obtained from an exploration program. Minimize environmental impact, since extracting large amounts of ore is not required.
Given todays need for quick decisions, tighter exploration budgets, higher confidence in production performance estimates and environmentally-friendly operations, the Mini Flotation Pilot Plant is destined to be the future for mineral processing plant design.
Our deluxe mini-flotation pilot plant can process in the range of 5 to 15 Kilos/hours our your representative sample. After completion of open-circuit or locked-cycle flotation tests, use the metallurgical parameters to better please your banker or

Flotation machine is for processing minerals by means of froth flotation, which is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity. Hydrophobicity differences between valuable minerals and waste gangue are increased through the use of surfactants and wetting agents. The selective separation of the minerals makes processing complex ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement. Phosphates and coal are also upgraded by flotation technology.
Flotation is a selective process and can be used to achieve specific separations from complex ores such as lead-zinc, copper-zinc, etc. Initially developed to treat the sulphides of copper, lead, and zinc, the field of flotation has now expended to include platinum, nickel, and gold-hosting sulphides, and oxides, such as hematite and cassiterite, oxidised minerals, such as malachite and cerussite, and non-metallic ores, such as fluorite, phosphates, and fine coal.

New DELKOR BQR flotation cell with MAXGen mechanism, core to process solution for recovery of valuable minerals from tailings stream, with proven DELKOR high-rate thickeners and horizontal vacuum belt filters helping to reduce tailings water loss, commissioned in India.
The first commercial application of the DELKOR BQR flotation cell equipped with the MAXGen mechanism is currently being commissioned on a project where the technology will be applied to maximize limestone recovery. The flotation cells were ordered by one of Indias leading cement producers, as part of a contract covering the supply of flotation, thickening and filtration equipment for one of its cement works in India.
DELKOR BQR flotation cells, equipped with the MAXGen mechanism, achieve superior process performance in maximizing recovery. DELKOR BQR flotation cells achieve optimum operation through improved particle-bubble interaction, faster flotation kinetics and precise froth level controls.
The order was received following the development of a process solution by DELKOR India to reduce the high levels of limestone and water that the plant was losing in the tailings discharged from the limestone washing plant into the tailings pond. Besides the loss of valuable minerals, the water loss meant that the tailings ponds were filling up at an unacceptably fast rate, while also contributing to water scarcity.
The process solution was developed based upon extensive laboratory and pilot scale test work by specialists at our Bengaluru lab center, which demonstrated the advantages of the MAXGen mechanism in optimizing recovery of limestone from the washing plant tailings. In addition, bench scale tests with high-rate thickeners and a vacuum belt filter demonstrated the potential for water recovery. The resulting process flowsheet includes flotation, dewatering and filtration equipment. The flotation plant will thus minimize limestone loss into the tailings, while the dewatering equipment will provide between 85 and 90% water recovery. The tailings cake generated from the flotation plant will be dry enough to be stacked, after filtering, for use as mine backfill.
As a result of this environmentally-friendly solution, both the mine and tailings pond life will be significantly increased, with the water that is recovered being re-used in the process immediately, thus reducing the fresh/make-up water requirement in the plant.
Ramesh Mahadevan, Regional Managing Director DELKOR, had this to say upon commissioning, The commitment and time our process team invested in demonstrating the advantages of the MAXGen mechanism in terms of grade, recovery and power consumption, were without doubt a deciding factor in winning this important contract. This is an environmentally friendly and important project for us and a key reference for DELKOR and our BQR flotation cell with MAXGen mechanism for the future. This project only serves to show that, It pays to talk to a specialist!
