Decreasing level. of viscosity and increasing dissolve oxygen means higher dissolution rate will achieved and will give higher gold extraction levels and also impact on getting higher throughput. By that improvements, average gold extraction in 2013 is increase 2.5 - 4 % compare to average gold extraction in 2012.

Many modern gold plants incorporate gravity circuits as part of their overall flowsheet, and it is estimated that about 10% of the new gold produced each year is recovered by this technique. The advantages and disadvantages of gravity separation are similar to heap leaching. It is a very simple and low cost process, but gold recovery is usually ...

The extraction of gold by the cyanide-method is of great technical importance. It is effected by lixiviation with a solution of potassium cyanide, the gold being precipitated either by addition of zinc or electrolytically. The process was suggested by Mac Arthur and Forrest in 1385, and is based on the well-known solubility of gold in potassium ...
