The principle of gravity separation used for the alluvial gold mining is to separate the gold concentrate from other minerals according to the different ore weight in the original ore. The first step of the gravity process is desliming, which removes the dirt from the mineral.

Gold Recovery And How To Choose The Right Process

Free-Milling Gold. 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
