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
In general, the most difficulty of the polymetallic sulfide ores separation is the separation among several kinds of ores, especially those low-graded ores with complex embedded features. Therefore, its a significant step for separating lead-zinc, copper-zinc, copper-lead to choose right flotation reagents.
The copper ore mined from a deposit has a copper content of about 1 , and is refined to a copper concentrate with a grade of about 20 to 40 through a process called ore dressing, including crushing and polishing. This copper concentrate is then smelted in a refinery to raise the copper grade to nearly 99 . Copper ore contains a variety of minerals other than copper-containing minerals ...
Copper beneficiation technology basically includes crushing, grinding, grading, sieving, sorting, drying and other processes.

Copper and silver are indispensable natural resources for the development of global economy. During 60 years of companys activity, KGHM has extracted over a billion tonne of mining output and has produced 20 million tonnes of copper. Current deposits will suffice for the next 40-50 years of mining activities. The copper ore deposit operated by KGHM in Poland dips monoclinally

May 03, 2017 The working condition of a processing plant is constant and choosing the best processing solutions is related to the ore nature. Taking Jiangxi Dexing copper mineral processing as an example. Firstly, look at the copper mine process, the porphyry coppers is surrounding rock, mainly acidic porphyry, and metal minerals of this type of deposit are mainly chalcopyrite.
For many years the copper ore grades have been declining as exploitation of the higher-grade deposits progresses. On a worldwide scale, the mined ores contain an average of less than 1.0 Cu Fig. 5. In Chile, the copper grade of the ores is significantly lower than even that. In 2015, the average copper grade in the ores was only 0.65 .
