Recovery Process Of Free Milling Ores

Freemilling gold gold ore is considered freemilling when over 90 of the gold can be recovered by a conventional gravitycyanidation process with low reagent consumptions at a grind size of 80 passing 75 181m some examples of freemilling gold ores include quartzveined deposits and oxidized ores sulfideassociated gold.

We are committed to building crushing, industrial grinding, ore processing and green building materials, and provides intelligent solutions and mature supporting products.
