Copper Mining and Extraction Sulfide Ores

Copper minerals and ore are found throughout the Earths crust. They occur in both sedimentary and igneous rocks. The outer 10 km of the crust contains 33 g of copper for every tonne of rock. This is not enough to makemercially viable to extract the rock. Copper mines are only set up where there is more than 5 kg of copper per tonne of rock 0.5 by mass. Ideally, the figure should

Extraction Of Copper Mining, Concentration, Smelting

The percentage of copper in the actual ore is too low for direct extraction of copper to be viable. The Concentration of Ore: The ore is crushed into a fine powder and a suspension is created in water. To this are added, Collectors and Froth Stabilizers. Collectors pine oils, fatty acids etc increase the non wettability of the metal part of the ore and allow it to form froth and Froth

Chiefly copper ores of the porphyric type disseminated copper ores with low concentrations of copper below 0.6 Cu are leached in this way. For instance in some states of the U.S.A. at some open pit mines, in which low grade copper ores are excavated, big dump leaching facilities are operated. The height of the dumps ranges from 20 m to about 200 m and they may contain up to 10 9 t of ore

Copper Mining and Processing: Processing of Copper Ores

Copper oxides are more abundant near the surface, but are considered low grade ore, with a lower concentration of copper. Although this requires more ore to be extracted and processed, this process is less expensive, so oxides can still be mined at a profit. On the other hand, while copper sulfide ores are less abundant, they contain higher amounts of copper. Although the processing costs are
