O idized Vs Sulfide Gold Ore

Both the veining and massive ores can be subdivided on the basis of their mineral constituents into (i) gold–galena–tetrahedrite–tellurides (especially altaite) ore; (ii) gold–arsenopyrite–pyrite ore; and (iii) pyrite. Mineralization mainly in quartz–carbonate veins is preferentially confined to the late carbonates.

minerals free fulltext gold in the oxidized ores of. gold ores can be classified into 11 types (Table 1). Some metallurgical implications to these gold ore types are summarised below Placers, quartz vein gold ores and oxidized ores Generally, placers, quartz vein gold ores and oxidized ores are free-milling and gold can be recovered by gravity and/or direct cyanide leaching.

Abstract. Gold is present in refractory sulfide gold ores mainly in arsenian pyrite and arsenopyrite, where it occurs in both the chemically bonded state and as nano-size grains of metallic gold. During roasting or pressure oxidation, the sulfide matrix is destroyed and essentially all the gold is converted to the metallic form.

The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (e.g., 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for extraction by cyanidation (see below).
