The history of mining industry is as long as human civilization. At the beginning, mining industry was growing very slowly, it is mainly support by human power, and there are not so many types of mining equipment. With the development of mining industry, more and more mineral resources are exploited, the increasing number of stone quarries and mining plants are established all over the world. Crushing is the primary and integral stage in mining operation. Crushing plant is important for mining industry. With the mining technology development, high advanced stone crushing plant are developed, especially portable stone crusher machine, which is gradually replacing traditional stationary crushing equipment.
Stone crushing plant industry has long history.At early time, crushers are machines which use a metal surface to break or compress materials into small fractional chunks or denser masses. Then, many different types of crushing plants are developed with various working principle, producing different particle size and applying in different crushing applications. Portable stone crusher machine is new types of crushing equipment, which is completely mobile and flexible for modern crushing requirements for recycling, construction, quarrying, and mining applications.
The main advantage of portable stone crushing machine is their ability to maximize productivity and reduce operating costs. The mobile stone crushing machine can be positioned close to the working face and then relocated under its own power in as little as 20min. The potential cost savings arising from the use of a mobile crushing and conveying system based at the rock face can be significant. SBM is world leading stone crushing equipment supplier and manufacturer; we provide complete series of portable stone crushing machine for sale.

The RETSCH pulverizer range covers applications from the preliminary size reduction of particles of several centimeters to fine grinding down to the nano range. Retsch Pulverizer Mill.A good pulverizer guarantees reproducible sample preparation, which is the basis for any reliable and accurate laboratory analysis. RETSCH products turn any laboratory sample into a representative part with required homogeneous analytical fineness.
Our comprehensive range of the most modern pulverizer mills and crushers are suitable for coarse, fine and ultra-fine size reduction of almost any material. The wide selection of grinding tools and accessories not only ensures contamination- free preparation but also adaptation to the specific requirements of such different areas of application as construction materials, metallurgy, foodstuffs, pharmaceuticals or environment. Particle size reduction of solids or bulk materials is required when the particles are too coarse or the material is too inhomogeneous for subsequent processes such as analysis, division, mixing or further processing. The standard deviation of any subsequent analysis can be minimized drastically by particle reduction and homogenization of the analysis sample.
If the initial particle size of the sample is coarse, it might be necessary to use two different pulverizer machines, one for preliminary size reduction and one for fine grinding, to achieve analytical fineness. To choose suitable grinding tools is also part of the selection process for finding the right pulverizer for your material. Here the important criteria are hardness, abrasion resistance, possible contamination and, for ball mills, the energy input.
With a RETSCH pulverizer you can rely on more than a century of experience and the best of German engineering technology. You will receive a product that is long-lasting, reliable and engineered with an eye for detail. Have a look at our company video for some impressions on how we work:

JXSC gold mining solutions design allows you to start recovering minerals with a base wash plant (scrubber / concentrator) unit. Various crushing, milling equipment can be ordered to make your solution more comprehensive. This can be implemented at a later stage, once you have begun to see an initial return on investment. This way, JXSC provides miners with a low capital starting point. The income that these base plants generate can then be used to fund their further expansion and enhance recovery.
Prominer maintains a team of senior gold processing engineers with expertise and global experience. These gold professionals are specifically in gold processing through various beneficiation technologies, for gold ore of different characteristics, such as flotation, cyanide leaching, gravity separation, etc., to achieve the processing plant of optimal and cost-efficient process designs.
Based on abundant experiences on gold mining project, Prominer helps clients to get higher yield & recovery rate with lower running cost and pays more attention on environmental protection. Prominer supplies customized solution for different types of gold ore. General processing technologies for gold ore are summarized as below:
For alluvial gold, also called sand gold, gravel gold, placer gold or river gold, gravity separation is suitable. This type of gold contains mainly free gold blended with the sand. Under this circumstance, the technology is to wash away the mud and sieve out the big size stone first with the trommel screen, and then using centrifugal concentrator, shaking table as well as gold carpet to separate the free gold from the stone sands.
CIL is mainly for processing the oxide type gold ore if the recovery rate is not high or much gold is still left by using otation and/ or gravity circuits. Slurry, containing uncovered gold from primary circuits, is pumped directly to the thickener to adjust the slurry density. Then it is pumped to leaching plant and dissolved in aerated sodium cyanide solution. The solubilized gold is simultaneously adsorbed directly into coarse granules of activated carbon, and it is called Carbon-In-Leaching process (CIL).
Heap leaching is always the first choice to process low grade ore easy to leaching. Based on the leaching test, the gold ore will be crushed to the determined particle size and then sent to the dump area. If the content of clay and solid is high, to improve the leaching efficiency, the agglomeration shall be considered. By using the cement, lime and cyanide solution, the small particles would be stuck to big lumps. It makes the cyanide solution much easier penetrating and heap more stable. After sufficient leaching, the pregnant solution will be pumped to the carbon adsorption column for catching the free gold. The barren liquid will be pumped to the cyanide solution pond for recycle usage.
The loaded carbon is treated at high temperature to elute the adsorbed gold into the solution once again. The gold-rich eluate is fed into an electrowinning circuit where gold and other metals are plated onto cathodes of steel wool. The loaded steel wool is pretreated by calcination before mixing with uxes and melting. Finally, the melt is poured into a cascade of molds where gold is separated from the slag to gold bullion.
