Mineral processing, art of treating crude ores and mineral products in order to separate the valuable minerals from the waste rock, or gangue. It is the first process that most ores undergo after mining in order to provide a more concentrated material for the procedures of extractive metallurgy. The primary operations are comminution and concentration, but there are other important operations in a modern mineral processing plant, including sampling and analysis and dewatering. All these operations are discussed in this article.

Routine sampling and analysis of the raw material being processed are undertaken in order to acquire information necessary for the economic appraisal of ores and concentrates. In addition, modern plants have fully automatic control systems that conduct in-stream analysis of the material as it is being processed and make adjustments at any stage in order to produce the richest possible concentrate at the lowest possible operating cost.

Sampling is the removal from a given lot of material a portion that is representative of the whole yet of convenient size for analysis. It is done either by hand or by machine. Hand sampling is usually expensive, slow, and inaccurate, so that it is generally applied only where the material is not suitable for machine sampling (slimy ore, for example) or where machinery is either not available or too expensive to install.

Many different sampling devices are available, including shovels, pipe samplers, and automatic machine samplers. For these sampling machines to provide an accurate representation of the whole lot, the quantity of a single sample, the total number of samples, and the kind of samples taken are of decisive importance. A number of mathematical sampling models have been devised in order to arrive at the appropriate criteria for sampling.

After one or more samples are taken from an amount of ore passing through a material stream such as a conveyor belt, the samples are reduced to quantities suitable for further analysis. Analytical methods include chemical, mineralogical, and particle size.

Even before the 16th century, comprehensive schemes of assaying (measuring the value of) ores were known, using procedures that do not differ materially from those employed in modern times. Although conventional methods of chemical analysis are used today to detect and estimate quantities of elements in ores and minerals, they are slow and not sufficiently accurate, particularly at low concentrations, to be entirely suitable for process control. As a consequence, to achieve greater efficiency, sophisticated analytical instrumentation is being used to an increasing extent.

In emission spectroscopy, an electric discharge is established between a pair of electrodes, one of which is made of the material being analyzed. The electric discharge vaporizes a portion of the sample and excites the elements in the sample to emit characteristic spectra. Detection and measurement of the wavelengths and intensities of the emission spectra reveal the identities and concentrations of the elements in the sample.

In X-ray fluorescence spectroscopy, a sample bombarded with X rays gives off fluorescent X-radiation of wavelengths characteristic of its elements. The amount of emitted X-radiation is related to the concentration of individual elements in the sample. The sensitivity and precision of this method are poor for elements of low atomic number (i.e., few protons in the nucleus, such as boron and beryllium), but for slags, ores, sinters, and pellets where the majority of the elements are in the higher atomic number range, as in the case of gold and lead, the method has been generally suitable.

A successful separation of a valuable mineral from its ore can be determined by heavy-liquid testing, in which a single-sized fraction of a ground ore is suspended in a liquid of high specific gravity. Particles of less density than the liquid remain afloat, while denser particles sink. Several different fractions of particles with the same density (and, hence, similar composition) can be produced, and the valuable mineral components can then be determined by chemical analysis or by microscopic analysis of polished sections.

Coarsely ground minerals can be classified according to size by running them through special sieves or screens, for which various national and international standards have been accepted. One old standard (now obsolete) was the Tyler Series, in which wire screens were identified by mesh size, as measured in wires or openings per inch. Modern standards now classify sieves according to the size of the aperture, as measured in millimetres or micrometres (10-6 metre).

In order to separate the valuable components of an ore from the waste rock, the minerals must be liberated from their interlocked state physically by comminution. As a rule, comminution begins by crushing the ore to below a certain size and finishes by grinding it into powder, the ultimate fineness of which depends on the fineness of dissemination of the desired mineral.

In primitive times, crushers were small, hand-operated pestles and mortars, and grinding was done by millstones turned by men, horses, or waterpower. Today, these processes are carried out in mechanized crushers and mills. Whereas crushing is done mostly under dry conditions, grinding mills can be operated both dry and wet, with wet grinding being predominant.

Some ores occur in nature as mixtures of discrete mineral particles, such as gold in gravel beds and streams and diamonds in mines. These mixtures require little or no crushing, since the valuables are recoverable using other techniques (breaking up placer material in log washers, for instance). Most ores, however, are made up of hard, tough rock masses that must be crushed before the valuable minerals can be released.

In order to produce a crushed material suitable for use as mill feed (100 percent of the pieces must be less than 10 to 14 millimetres, or 0.4 to 0.6 inch, in diameter), crushing is done in stages. In the primary stage, the devices used are mostly jaw crushers with openings as wide as two metres. These crush the ore to less than 150 millimetres, which is a suitable size to serve as feed for the secondary crushing stage. In this stage, the ore is crushed in cone crushers to less than 10 to 15 millimetres. This material is the feed for the grinding mill.

In this process stage, the crushed material can be further disintegrated in a cylinder mill, which is a cylindrical container built to varying length-to-diameter ratios, mounted with the axis substantially horizontal, and partially filled with grinding bodies (e.g., flint stones, iron or steel balls) that are caused to tumble, under the influence of gravity, by revolving the container.

A special development is the autogenous or semiautogenous mill. Autogenous mills operate without grinding bodies; instead, the coarser part of the ore simply grinds itself and the smaller fractions. To semiautogenous mills (which have become widespread), 5 to 10 percent grinding bodies (usually metal spheres) are added.

Yet another development, combining the processes of crushing and grinding, is the roll crusher. This consists essentially of two cylinders that are mounted on horizontal shafts and driven in opposite directions. The cylinders are pressed together under high pressure, so that comminution takes place in the material bed between them.

The achievement means Kuvimba, where Government has majority holding, has managed to double the output at Freda Rebecca within a space of a year, making the mine the biggest in the country in terms of gold production.

Compared to last year after taking over, we were averaging 226kg per month. The success story is a combination of factors. Basically the key issue is re-investment in the business by our shareholder, which enabled us to recapitalise as well as have sufficient working capital. Combined with that is also team work from the employees, management and supervision. Its a team effort that resulted in the numbers.

Kuvimba Mining House chief operating officer, Mr Cobus Bronn, weighed in: KHM recognises and understands the importance of providing the required sustaining capital to the mine to ensure sustainable and improved production at the lowest possible operating costs. Freda Rebecca Gold Mine has a remaining life of mine of approximately five years and the company is actively looking to augment the current life of mine by evaluating near resources and secondly undertaking an extensive exploration plan to find and build the next mega mine to replace Freda Rebecca Mine.

Its current turnover is about US$25 million a month being boosted by international gold prices and nickel prices, a development which has seen the company contributing more than US$10 million to the Reserve Banks foreign currency auction system.

Gold is a dense, soft, shiny, malleable, and ductile metal. It is a chemical element with the symbol Au and atomic number 79. It has a bright yellow color and luster traditionally considered attractive, which it maintains without oxidizing in air or water. Chemically, gold is a transition metal and a group 11 element. It is one of the least reactive chemical elements, solid under standard conditions. The metal therefore occurs often in free elemental (native) form, as nuggets or grains in rocks, in veins and in alluvial deposits.

Gold ore processing plant is widely used in gold ore crushing and grinding process to resize and pulverize gold ores into 10mm to smaller than 1mm particles. As gold ores VHN hardness is between 60 and 105, SBM design gold ore crushing plant and grinding machine that can process gold ore. SBM gold ore processing plant includes mainly two series: crushing and grinding machines, both of which are welcomed by our customers. SBM gold ore crusher can produce gold products with the size between cm and mm. And our gold ore grinding machine can process gold ore into powder of nm grade.

State and gold content of gold in the mineral structure can be divided into the gold mineral gold deposits of gold minerals, gold-bearing minerals and gold - bearing minerals three categories. Independent minerals, means the so-called gold gold gold minerals and gold minerals in the form of output, it is the most important modes of occurrence of gold in nature, industrial development and utilization of the main object. So far, the world has found 98 gold minerals and gold-bearing minerals, common only 47 species, and direct industrial use mineral only 10 kinds of.

3) in the industrial and scientific and technological applications. Infrared reflectance close to due to the gold have unique perfect nature, it has a high resistance to corrosion stability; good electrical conductivity and thermal conductivity; the gold nuclei having a larger neutron capture cross-section; ; also widely used in the most important modern high-tech industry, and electronic technology, communications technology, aerospace technology, chemical technology, medical technology.

Most of the gold processing plant use jaw crusher as the primary crushing. CSB cone crusher is used as the intermediate crushing. The CSD cone crusher is as the fine crushing. The equipment potential to improve mineral production capacity, crushing process transformation, improve the utilization factor of the grinding machine, taken measures to implement the more crushing and less grinding to reduce the particle size of ore into the mill.

Flotation machine (also called Flotation separator) is applicable for the separation of nonferrous metal and ferrous metal and nonmetal, such as fluorite and talc. The impeller is driven by V-belts, which can bring the centrifugal effect to form the negative pressure. On the one hand, to inhale sufficient air to mix with ore pulp; on the other hand, to stir ore pulp and mix with medication to form the mineralized froth. To adjust the height of flashboard to control the liquid level and make the useful froth scraped by loam board. When flotation machine works, slurry is inhaled from the bottom of the trough to the space between impellers. Meanwhile, the low pressure air send by fan is sent to this area through the air distributor in the hollow shaft. After sufficient mixing, the slurry is pushed out by the impeller, and then goes to the whole trough. When the froth rises to the stable level, after the enrichment processing, froth overflows to the froth trough from the overflow weir. Another part of ore slurry flows to lower part of impeller for the remixing with air. The remained slurry flows to the next trough until it becomes residue.

(A) comprehensive utilization of mineral resources, inadequate laws and regulations, the comprehensive utilization of mineral resources, preferential policies are not in place. Adopting both rich and poor, low-grade ore and to carry out the comprehensive use of recycling useful components associated with the taxes charged according to the amount and quality, increase the use of cost, profit margins are low due to the recovery of this part of the resources even needed capital subsidy, , engage in comprehensive utilization but affect the economic efficiency of enterprises.

(B) loss of mineral resources, waste and destruction Most of the gold mines, especially small-scale mining is often the case where the low level of exploration under construction. Mine put into production, infrastructure, technological transformation at the same time, the majority of small businesses in the metallurgical process technology, low management level, coupled with the initial mining program ill-considered, often resulting in a large loss of resources, waste and destruction.

(D) investment in science and technology and personnel training is not enough emphasis Currently, the gold mine of comprehensive utilization of research are still weak, the depth and breadth of the comprehensive utilization of mineral resources research is not enough. On the one hand, the industrial sector dispersion of Geology and Mineral scientific research strength is not concentrated, apparatus, equipment, poorly equipped, do not form a fist. On the other hand, the comprehensive utilization of mineral resources, a serious shortage of basic research forces. Deployment of geological prospecting work, no deployment and comprehensive evaluation study on comprehensive utilization pilot study. Existing scientific research with low conversion rates.

Once extracted, the gold ore is pulverized to prepare it for refining. The gold is refined with one of four main processes: floatation, amalgamation, cyanidation, or carbon-in-pulp. Each process relies on the initial grinding of the gold ore, and more than one process may be used on the same batch of gold ore.

In this refining circuit, we can use electrowining cells, electrorefining cells and remelt furnace to refine gold ore. we also can use filter presses, mercury retorts and induction refining furnace to purify gole.
