Extremely Fine Gold Recovery Gold Recovery Methods

Apr 14, 2015018332I have a mine here that we get good gold from, the particle size is near 1000 mesh which I use for testing the sluice recovery and performance, and to experiment with methods to recover the gold.

How And Why Do We Produce Gold And Copper

In general terms, when gold is the only payable mineral present i.e. gt98-99 of the value, we can process the ore on the mine site and create gold bars. At both North Mara and Geita, gold is extracted using gravity techniques for the coarse, free gold and then cyanide to leach the finer disseminated gold. Gold bars are smelted at both mines.
