Copper Smelting Process - Furnaces Used, By-Products, and

Copper ore typically contains only about 0 6 of the actual copper mineral, the most common ore mined being chalcopyrite The ore is attained using traditional methods of underground and open pit mining, the later accounting for 90 of the ore used in smelting

Basics of mineral processing - SlideShare

Jul 29, 2017 · 3 The fundamental operations of ore-dressing processes are: a the breaking apart of the associated constituents of the ore by mechanical means severance and b the separation of the severed components beneficiation into concentrate and tailing, using mechanical or physical methods which do not effect substantial chemical changes 4

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 direct-smelting ores are produced, the bulk of the copper ore mined is concentrated The milling of copper ores as practiced in the larger
