Sarcheshmeh low-grade ore contains pyrite, which causes some problems in the flotation of copper minerals. In this study, A ferrooxidans was used to change the surface chemistry of pyrite and copper sulfide ores and consequently, their flotation behaviour. In the presence of A ferrooxidans and xanthate as a collector, pyrite was depressed

How is copper extracted from copper ore? Copper mining is usually performed using open-pit mining, in which a series of stepped benches are dug deeper and deeper into the earth over time. To remove the ore, boring machinery is used to drill holes into the hard rock, and explosives are inserted into the drill holes to blast and break the rock.

If uranium is present in the ore as part of a widespread silicate mineral with a weakly bound hydroxyl group, coffinite U (SiO4)i-x (OH)4x, its dissolution rate slows down. The presence of uranophane, a complex calcium hydroxysilicate Ca (UO2)SiO3 (OH)2-5H20, in the ore inhibits uranium leaching to a considerable extent.
