How Gold Is Mined
The gold mining operation stage represents the productive life of a gold mine, during which ore is extracted and processed into gold. Processing gold involves transforming rock and ore into a metallic alloy of substantial purity – known as dor – typically containing between 60-90% gold.

The Four Main Methods of Mining
04.12.2019In-situ mining (also called in-situ leaching or recovery) is a mining method that's used to obtain minerals like uranium and copper through drilled boreholes into a deposit. In-situ mining works by dissolving naturally occurring minerals that are in a solid state. A leaching solution is pumped into the boreholes where it makes contact with the ore.

What are the chemical and physical separation methods used in gold
The ore is crushed then the resulting powder is desolved in a cyanide complex there by converting the gold to a water-soluble coordination complex. From there the gold can be extracted by electrolysis or precipitation. This is the most commonly used leaching process for gold extraction, although there are others. 6 Sponsored by ZOIVATE
