Copper Ore Processing Methods

The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and directsmelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger

Refractory Gold Ore Treatment Methods

Mispickel (Arsenopyrite: FeAsS).6. When this mineral occursin a gold ore, a proportion of the gold is frequently in intimate association and only rendered open to cyanide attack by previous roasting. With a sweet roast, the calcine usually yields a high gold extraction with low lime and cyanide consumption.

The process mineralogy of gold: The classification of ore

The principal gold minerals that affect the processing of gold ores are native gold, electrum, AuAg tellurides, aurostibite, maldonite, and auricupride. In addition, submicroscopic (solid solution) gold, principally in arsenopyrite and pyrite, is also important.

Mineral processing Wikipedia

Mineral processing can involve four general types of unit operation: comminution particle size reduction sizing separation of particle sizes by screening or classification concentration by taking advantage of physical and surface chemical properties and dewatering solid/liquid separation. In all of these processes, the most important considerations are the economics of the processes and this is
