  • Gold Recovery And How To Choose The Right Process

    Gold ore is considered freemilling 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 gravitycyanidation process with low reagent consumption. Freemilling gold can be further classified into low grade and high grade

    The gravity concentration separation process gets more complex as the specific gravities between the valuable mineral and the gangue get closer. For example, complex gold in a sulphide complex of pyrite, must isolate a specific gravity of 19.3 for gold from 5.2 for pyrite. Using gravity to recover minerals in their coarsest fraction minimises
