Recovery of Gold and Silver from Ores by .

Recovery of Gold and Silver from Ores by .

In 1970, an oxidation treatment based on hypochlorite was developed to increase the recovery of gold from carbonaceous gold ores by cyanidation. In the early 1950's, attempts were made to employ carbon-in-pulp technology to recover gold from ores, but the fixed price of gold and increasing operational costs made cyanidation unprofitable.
