Apr 23, 2011· There are two main copper ore types of interest, copper oxide ores and copper sulfide ores. Both ore types can be economically mined, however, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts for about 50 percent of copper production.
200tons Oxide/sulfide Copper Mining Flotation Machine Flotation Cell, Find . concentration, the mineral is usually transferred to the froth, or float fraction, .. flow for various ores beneficiation, including iron ore, tin ore, copper ore, gold ore,.
improvement of sulphideoxide copper ores processing through the use of mixed collector systems has surged. The flotation of a natural porphyry copper ore with bornite and malachite was investigated via fundamental work with pure minerals and a benchscale testing regime. The
Coppercontaining rock, or copper ore, holds only a small percentage of copper. Most of the rock is unwanted material, typically referred to as gangue. There are two main copper ore types of interest: copper oxide ores and copper sulfide ores. Both ore types can be economically mined, though they are processed in different ways.

Copper Mining Info The above flowsheet shows a basic copper mine process, from mine to metal There are two distinct types of copper ore, the sulfide ore and the oxide ore The sulfide ores are beneficiated in flotation cells, while the oxide ores are generally leached First the copper ore from a open pit mine is blasted, loaded and .
Charcoal ore flux m The Egyptian copper smelting furnace was filled with a mixture of copper ore, charcoal and iron ore to act as a flux. It was blown for several hours by foot or hand bellows. By the end of the smelt the copper had separated from the slag, which was tapped off.
The fitting of flotation date to a flotation kinetic equation shows that the copper oxide ore, cuprite, malachite and chrysocolla in this ore are consistent with a first order kinetic equation. The rate constants for copper oxide, cuprite, malachite and chrysocolla are,, and respectively.
And the copper oxidation ratio of the ore is %, According several flotation tests, finally found that the optimum reagents dosage are: butyl xanthate 90g/t as collector, pine oil 35g/t as ing, sodium sulphide1000g/t, lime3000g/t, and the flowsheet is one stage of roughing, three stage of cleaning and two stage of scavenging operationg in the close circuit under the grinding fineness is 85% .
The Flotation of Samples with Sulfurization of Oxidized Copper Ore. For the sulfurization process, two samples were prepared in two different autoclave mediums: Sample A containing H2S + g H2O for one kg of copper ore, and Sample B containing g H2S + g H2O for one kg of ore.
flotation in mining copper and gold oxide ore. Copper processing is a complicated process that begins with mining of the ore The most common types of ore, copper oxide and copper sulfide, undergo two purify copper from copper sulfide ores, in four basic steps: 1) .
unrecovered copper in LQ ore was present as chrysocolla, % as malachite and % as chalcopyrite and therefore LQ ore required alternative flotation methods for the recovery of the oxide minerals. Comparison of slug sulphidisation and controlled potential sulphidisation (CPS) of LQ ore have shown that CPS performs better than slug sulphidisation only when the
1993). The physical properties of copper oxide ores are such that the high production of fines (38 µm size fraction) is inevitable during the crushing and milling stages. The evaluation of the effects of fine copper oxide ore on the results of flotation performance is a key .
