Jun 07, 2021 Smelting. Copper smelting involves three steps Roasting First, ore concentrates are roasted or heated to remove sulfur and moisture. Smelting Then, copper concentrates are mixed with silica (sand) and limestone and heated in a furnace to form two naturally-separating layers. 4. Beneficiation of Copper Ore. The next step in processing is called beneficiation. This is the first step in concentrating the copper into a more useable form. 5. Smelting and Extraction.

Sulfidic copper ores are too dilute for direct smelting. Smelting these materials would require too much energy and very large furnace capacities. The copper ore coming from the mine (0.5 1 % Cu) must be concentrated by beneficiation. The valuable minerals like chalcopyrite are intergrown with gangue. Mar 20, 2016 The simplest case may be represented by a low grade copper ore which in its natural state could not be economically shipped or smelted. The treatment of such an ore by flotation or some other process of concentration has this purpose to concentrate the copper into as small a bulk as possible without losing too much of the copper in doing so.

Smelting Smelting involves the application of heat to a charge of copper ore concentrate, scrap, and flux to fuse the ore and allow the separation of copper from iron and other impurities. The smelter furnace produces two separate molten streams copper It does this by coating the concentrate slurry onto a support rock, or substrate material, and stacking this coated material in a bioxidation heap. The support rock itself may be a low-grade copper ore. The ratio of support rock to concentrate is in the range of 51 to 101 by weight.

12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg) (1.6 millon tons) of ore produced in 1991. Copper is produced in the U. S. primarily by pyrometallurgical smelting ... Thus copper concentrate can be flash smelted in a first operation to matte grade of about 55% while producing a slag which can be discarded the matte can be granulated, ground and smelted in a second flash melter to yield white metal or blister copper with the slag from the second flash smelter being returned to the first smelter operation.

Copper ore concentrate processing. Because the metal concentration is usually quite low in nonferrous ores, the first stage in mineral production at the mine is ore beneficiation, usually consisting of the processes of milling (crushing and grinding) and concentrating (usually consisting of a series of steps including flotation and dewatering by thickening and filtering). The disclosure is particularly concerned with the removal of radioactive impurities from copper ore or copper concentrate during or after smelting.
