Different Gold Ore Processing Methods for 5 Kinds of Gold Ore. According to the degree of ore oxidation, gold ore can be divided into primary (sulfide ore) ore, partially oxidized (mixed) ore and oxidized ore. Here are the different kind of gold ore processing methods used for five types of gold ore. Let's drive in now.

Mineral processing, mineral beneficiation, or upgradation involves handling three primary types of ROM material, which have been blasted, fragmented, and brought out from an in situ position. These materials can be used directly or by simple or complex processing and even by applying extractive metallurgy like hydrometallurgical or pyrometallurgical methods.
