12.3 Primary Copper Smelting

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

Copper–gold ore processing with ion exchange and SART

Copper–gold ore processing with ion exchange and SART

Oct 01, 2014 The deposit at Gedabek is a copper–gold porphyry, comprising both oxide and sulphide ore mineralisation, which is being mined at the rate of about 1 million tons of ore per year. Ore processing is by conventional cyanide heap leaching, which produces a pregnant leach solution (PLS) containing 1–2 ppm of gold, together with 1000 ppm or more

This means that 95.7% of the copper present in the ore was recovered in the concentrate, while the rest was lost in the tailings. (c) The % Cu Loss can be calculated by subtracting the % Cu Recovery from 100%: % Cu Loss = 100 – 95.7 = 4.3% This means that 4.3% of the copper present in the ore

Copper. Part 9

The solution finished, the liquor is drawn off, the ore is washed, and the copper is precipitated by scrap-iron, a part of the cement reaching a yield of 80 per cent. of copper after drying. The black copper is smelted in a reverberatory furnace and then fined; the rest , which is less rich and very pulverulent, is passed into a blast

The deposits contained nearly 4.5 million tons of 13 percent copper and 65 grams of silver per ton, some of the highest grade deposits ever mined (Bateman, 1942). The ore at Kennecott contained an amount of copper equivalent to a 100-million-ton typical porphyry copper deposit, which is currently one of the primary types of copper deposits

iron processing - iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is
