Gold mining is a global business with operations on every continent, except Antarctica, and gold is extracted from mines of widely varying types and scale. Mines and gold mining operations have become increasingly geographically diverse, far removed from the concentrated supply of four decades or so ago when the vast majority of the world''s gold came from South Africa.

Nimba will be an open pit operation using the truck and shovel method to extract ore. Metallurgical test results indicated the use of a simple dry plant process featuring crushing and screening to produce highgrade lump in the early stages of production. It will be followed by the addition of a wet process, which is anticipated to produce highgrade lump as well as fine ore. Plateaus two and

Processing lowgrade ore is relatively simple while higher grades require more extensive processing. Step #8 – Refining (offsite) Once basic processing is done, the ore is taken to a refinery where the remaining impurities are stripped out. Crude gold is melted and treated with chloride, which converts any remaining foreign metals to chloride which will then drift off the gold. The result

Hard rock ores have formed the basis of the majority of commercial gold recovery operations since the middle of the 20th century where open pit and or subsurface mining techniques are used. Once the ore is mined it can be treated as a whole ore using a dump leaching or heap leaching processes. This is typical of lowgrade, oxide deposits.
