Gold Extraction & Recovery Processes - 911 Metallurgist
Gold Recovery. Gold recovery comprises similar stages to the processing of most ores. First, the valuable minerals are separated from the gangue through concentration. The final concentrate is obtained by repeated processing and is smelted or leached in order to get a Dore bar. In generals, the concentration of gold includes three stages: roughing, cleaning and scavenging. The reason ofGold Recovery And How To Choose The Right Process,,Blasting, crushing, and grinding are necessary to liberate the gold for recovery.
