Milling Process Of Gold

Gold Processing Plant

Gold milling, which is also known as fine grinding, pulverising or comminution, is a grinding process that reduces materials into a powder or finer sized particles. Milling is used to recover the maximum amount of gold from the ore by finely grinding it so that gold particles can be removed through gravity separation and/or chemical extraction.
