Leaching   Mining Fundamentals

Leaching Mining Fundamentals

Post leaching, the rocks are left with a smaller proportion of minerals than they originally contained. The leaching process in mining is carried out either as heap leaching or insitu leaching. Precious metals such as gold are extracted from their ores by a cyanide or ozone leaching process.

Concentration of Minerals Article about Concentration of

Concentration of minerals is performed by means of a series of consecutive operations, which constitute the enrichment program. The initial operation is crushing and pulverization of the raw material to reduce it to a particle size that is suitable for existing concentration processes and equipment, as well as for the separation of concretions and formation of particles of individual minerals.
