Silver is a soft, white, lustrous transition metal, it has the highest electrical conductivity of any element and the highest thermal conductivity of any metal. Silver is commonly extracted from ore by crushing, grinding, smelting or chemical leaching.The crushing and grinding operations are an important part of the processing of mineral resources, and it is also operation with high investment and high energy consumption. In the case of metal mines, equipment investment in crushing …

The crushing process often requires different stages of grinding, since there is no crusher or mill capable of converting large mineral formats into micronized fines. Thus, our range of crushers and mills covers the whole size reduction process, from the primary crushing stage to the refining grinding.Crushing and grinding are known as comminution procedure where the major operations are intensively related to liberation and reduction of particle size by means of different technologies.

Screening and diverting fine particles significantly increases the performance of the crusher. 2. Crushing and stock piling. This step involves breaking up the iron ore to obtain an F 80 grind size before it can be ground. Once the ore has been crushed, it is diverted to a stockpile.
