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 Poor sulfide gold ore processing Polysulfide gold ore processing Goldbearing polymetallic ore Gold can be freed from these ores or concentrates by treating them with various oxidizing processes The most common method is to roast goldbearing minerals at temperatures of 450° to 750° C (840° to 1,380° F) to destroy the interfering sulfidesGold processing Mining and concentrating Britannica
