     · The separation of the minerals makes processing complex (that is, mixed) ores economically feasible. Image used with permisison from Wikipedia (credit: Dhatfield ). Other ways to concentration minerals include approached based on density (Froth Flotation) used if ore density is less than density of impurities, or via melting points, or magnetic properties (Magnetic separation).

  • Unit 3 Reading: Mining and Mining Impacts

     · During the exploration process, a mining company seeks an area where the desired mineral resource is concentrated and attempts to determine the size of the ore body and the mineral resource's ore grade. Higher ore grades (higher concentrations) make the mining project more viable (see Table 1). However, there are many other factors that can influence the decision to extract ore .

  • Metallic Minerals Processing

    Metallic mineral processing typically involves the mining of ore from either open pit or underground mines; the crushing and grinding of ore; the separation of valuable minerals from matrix rock through various concentration steps; and at some operations, the drying, calcining, or pelletizing of concentrates to ease further handling and refining. Figure is a general flow diagram for ...

     · Ore is brought to the surface through tunnels and shafts for processing, and waste rock for disposal. Subsurface mining can be classified according to the type of shafts used, the method of extraction or the technique used to reach the deposit. Drift mining uses horizontal access tunnels, diagonally sloping access shafts are used by slope mining, and shaft mining uses vertical access .

     · The problematic ore might be stockpiled until sufficient inventory allows one to process that ore ( campaign) through the mill. Such stockpiles will only grow as large as the operator allows them to grow. At any time the operator can process the material and deplete the stockpile. Be aware that mining operations might still be mining other ore types, then those ores may need to be ...

  • Leaching

    Leaching is a chemical process in mining for extracting valuable minerals from ore. Leaching also takes place in nature, where the rocks are dissolved by water. 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.
