How Gold Is Mined

The lifecycle of a gold mine. People in hard hats working underground is what often comes to mind when thinking about how gold is mined. Yet mining the ore is just one stage in a long and complex gold mining process. Long before any gold can be extracted, significant exploration and development needs to take place, both to determine, as accurately as possible, the size of the deposit as well

What are the chemical and physical separation methods used

Answer: Physical separation usually involves the difference in mass between gold and most of the other associated minerals. Once the gold is physically separated from the host material and of a relatively similar size it can be separated using a rotary bowl spinning at high speed with water to fl

Vanadium element extraction methods

MINING AND PROCESSING : The major ores of vanadium are patronite (VS 4), carnotite [K 2 (UO 2) 2 (VO 4)3H 2 O], and vanadinite [Pb 5 (VO 4)3Cl].Since much of the vanadium present in the igneous rocks occurs in the relatively insoluble trivalent state, substituting for ferric iron in ferromagnesium silicates, magnetite (an iron ore), ilmenite (a titanium ore), and chromite, the ore deposits

Platinum Mining and Refining

Mercury

Small-scale gold mining is the largest anthropogenic contributor of mercury pollution on planet Earth. The miners grind gold ore together with mercury in order to recover the fine gold grains. The gold amalgam is burned whereby the mercury evaporates and gold is left behind. This processing extracts only a fraction of the gold in the ore and the released mercury causes serious global health
