Commonly used gold ore beneficiation mainly includes classifiers, ball mills, flotation machines/magnetic separators, mixer, and concentrators. Recently, Hongxing Mining Machinery Co., Ltd. has contracted the gold mining plant project in Tanzania. Let's take a look at the application of gold ore dressing equipment in this project.
Because the gold ore beneficiation project is located in Tanzania, Africa, where the environment is relatively harsh, it is difficult to operate the project whether in construction, management, or work coordination, and it is very different from domestic projects. The main mineral composition of the mine is natural gold and quartz, followed by limonite, goethite, chalcopyrite, chalcopyrite, pyrite, occasionally sphalerite, stibnite.
After several trials, Hongxing Mining Machinery Co., Ltd. adopted two grinding stages in the grinding system. In the first stage, a grate ball mill and a spiral classifier are adopted. The content of the -200 mesh ore in the slurry is about 65%. The second stage of grinding will be classification in advance and combination, which will help to improve the classification efficiency of grinding. The particle size is -200 mesh, accounting for 90%-95% or more, which meets the particle size requirements of the project. In the gold ore separation operation of Hongxing, not only the construction period is short, the equipment quality is high, but also the investment cost is greatly reduced. The customer is very satisfied with this and is very looking forward to the red star machine again in the future mineral processing line project. Continued cooperation.cooperating with Red Star Machinery again in future mineral processing projects.
The above is the application of gold ore dressing equipment to the Tanzania gold ore dressing plant project. We will continue to share more case projects to help customers have a comprehensive understanding of the Hongxing mining machines.

We will provide you with satisfactory equipment, reasonable price, good service!
The 911MPEPPGR426 is a small 300 kilo to 3.5 ton per 24 hour day capacity grinding mill acting primarily as a rod mill but can effortlessly be converted to a ball mill. Thanks to the integrated spiral classifier, it forms an easy to operateclosed-circuit grinding plant. It includes a fine ore hopper,vibrating feeder and starter rod load.
It is the perfect small grinding circuit for pilot plant operations or small micro mining. Under specific conditions, it will grind finely crushed ( -6mm) ore to 75 microns.This is a Dual Media mill (rod or ball).

Quartz sand is a kind of non-metallic mineral.Its main mineral composition is silica (SiO2). Quartz sand is made by quartz ore crushing, screening, washing and other processes. its hard, wear-resisting, chemical properties of stability is widely used in glass, casting, ceramics and refractory materials, smelting ferrosilicate, metallurgical flux, metallurgy, construction, chemical, plastic, rubber, abrasive and 
Slag is a common raw materials for cement industry. The hardness of slag is around 6-7 in Mohs scale (harder than cement clinker). For the aim to grind slag (15-20 mm) to a final fineness of 30 microns. After the slag dry, the slag less than 50mm fed into the rolling mill, the slag will

The capacity is different according to different size. This system is also for iron avoidance superfine grinding for other hard materials, for example: 
ZJH mainly focus on producing and supply crushers, ore grinding equipment, mineral Beneficiation equipment, laboratory and pilot scale ore dressing equipment for Mining and Mineral Processing Industry. Our aim is to work together with Mines, Mineral Beneficiation Plantsfor helping to reduce the operating cost ,to improve the operating efficiency.
The final fineness of the product mainly depends on the number of times the ore particles pass through the grinder. The longer the grinding, the smaller the particle size. Separate crushing and grinding steps are necessary, the ball mill can only receive the broken ore particle, and then grind to the grinding fineness required for flotation.
In order to separate the concentrate from the ore, the ore should be ground fine enough to release the target mineral from the non-mineral grains. The degree of grinding required for this depends on the size of the mineral particles in the ore. A laboratory-scale flotation test is usually required on materials of different particle sizes to determine the grinding particle size required to release the target minerals.The fineness of the ore particles produced by grinding is crucial to recover the minerals by flotation. The most common grinding machines are semi-automatic (SAG) and automatic (AG) mills and ball mills.
Determining an optimal grinding size can maximize the recovery of target minerals in the subsequent flotation process.The grinding size is too large, and some ore particles and non-ore particles cannot be separated, thus preventing their flotation. If the particle size is too fine, the bubbles that rise during the flotation will push the very fine ore-containing particles away, preventing them from contacting the bubbles, thereby reducing their ability to be recovered into the concentrate.In addition, extremely fine rock and iron sulfide particles may agglomerate with extremely fine sulfide ore particles, preventing the ore particles from floating.
According to the test, the particles usually need to be ground to a diameter of about 100 mm to release minerals from each other. When the particles are less than about 10 mm, this is not conducive to the flotation effect.Grinding operations are very power-hungry, which is another reason to avoid excessive grinding.
The crushed products are ground in SAG or AG mills. The self-grinding machine can grind ore without grinding media such as iron ball, or steel rod, as long as the hardness of the ore is sufficient for the rolling ore to grind by itself.A large vibrating screen is used to sieve the ground products to separate the oversized particles. A small cone crusher to recover the oversized material, and then sent them return to the SAG or AG mill for re-grinding. The correct size material is sent to the ball mill for final grinding.
The ball mill is the fine grinding machine connect the SAG or AG mill and flotation machine. Ball mills produce fine particles with a uniform size for flotation, its grinding medias commonly are steel ball. The ball mill rolls grinding media together with the ore, as the ore grinds, these balls initially 5-10 cm in diameter but gradually wear out.Grinding is always carried out under wet conditions, with about 70% solid mixture in water.This procedure maximizes ore production and minimizes power consumption.Get in Touch with Mechanic
