  • 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 which helps determine the most economical and optimal gold recovery

    The maximum recovery is 100 which refers to the raw material or the ore before beneficiation. But the ultimate grade of a substance in the ore is its value in the pure mineral. For example the lead grade in PBS is 86.59 percent. We cannot go beyond this value thus the metal grade cannot be more than 86.59 percent in the concentrate.
