Gold Recovery And How To Choose The Right Process
Gold ore is considered free-milling when it is easily liberated by grinding and separated from the other minerals. A more technical definition is that you are able to recover over 90% of the gold by a conventional gravity-cyanidation process with low reagent consumption. Free-milling gold can be further classified into low grade and high grade ...
