ProcessesIn the case of copper, it is worth extracting when there is about 2 kg of copper per 1,000 kg of ore (%). Copper minerals are found in over one hundred varieties, although only a few have been worked for copper on a large scale. The most abundant ores are chalcopyrite and bornite, which contain both copper and iron sulphides. These account for about 80% of the world's known ores. Copper ...

Development of copper recovery process from flotation ...Jun 15, 2018 · Jun 15, 2018 · For that reason, the vast majority of copper extracted from these copper minerals is usually by pyrometallurgical processes,, flotation followed by smelting and refining [2,4,5]. Generally, the flotation tailings are produced as a byproduct during the beneficiation of copper ore, namely froth flotation before the pyrometallurgical processes.
OPTIMUM CONDITIONS FOR COPPER EXTRACTION FROM THE ...Optimum conditions for copper extraction from the flotation waste 173 Fig. 1. Loion of the flotation tailings ponds near the city of Bor Several methods have been proposed to reduce or eliminate the problem arising from the flotation tailings ponds [10, 19–21]. One of the methods was based on acidic leaching of kaolinite from the flotation waste [10] which resulted with obtaining the ...
