Haul trucks transport the ore from open pits or underground operations to processing operations. Some ores may be stockpiled for later processing. Rock that is not economical to mine is stored in waste rock storage areas. The grade and type of ore determine the processing method used.

Surface mining. Surface mining is exactly what the word says - digging rocks out from the surface, forming a hole or pit. In South Africa, this method is used to mine for iron, copper, chromium, manganese, phosphate and coal. Surface mining is also known as open pit or open cast mining. An open pit coal mine.

Jan 01, 2012 · 1.2. Chalcopyrite Ore Production The sulfide ore minerals including chalcopyrite (CuFeS 2), sphalerite (ZnS), galena (PbS) provide the major sources of the world's base metals (Cu, Zn, Pb, respectively), whereas pyrite is virtually ubiquitous as a metalliferous mineral in sulfide ore deposits (Crang and Vanghan, 1994).The first step in recovering metal from their mineral is that of finding

The oxidized ores can be reduced directly to metallic copper by heating with carbon in a furnace. The sulfide ores require a more complex treatment in which low-grade ores must be enriched before smelting begins. Sulfide ores are more important commercially. Half of the world's copper deposits are in the form of chalcopyrite ore (CuFeS 2).

Metallic sulfide mining (aka hard rock mining) is the practice of extracting metals such as nickel, gold and copper from a sulfide-rich ore body. Sulfides are a geologic byproduct of mining in this area, and by exposing sulfides to the air and water in our atmosphere, sulfuric acid can be created — threatening to poison the nearby water
