Porphyry copper ores, usually medium to medium hard, require grinding to about 65-mesh to economically liberate the copper minerals from the gangue.Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a commercial scale early in the 20th century toFlotation | Mineral Processing, Separation & BeneficiationFigure 1 is a generalized diagram of a conventional copper flotation plant from the point where ore first enters the circuit to the production of concentrate and tailings. To prepare ore for the flotation process, run-of-mine ore, which may contain from about 2 to 5 percent water, by weight, when mined, isEstimated Water Requirements for the Conventional Flotation of Copper Oresاحصل على السعر
The fresh copper oxide mineral surfaces exposed during crushing and grinding have a significant effect on subsequent flotation [23], [24], [25], [26].Many dangling bonds exist on fresh mineral surfaces because of destruction of the original lattice bonds, and the copper oxide mineral surface often shows strong polarity because of the existence of ionic bonds.for copper has resulted in increased ore processing by flotation plants around the world. The depletion of high-grade ores, increased demand for metals and separation difficulties associated with low-grade or refractory ores, has resulted in new flotation challenges in terms of economic and sustainable beneficiation of these ores.Review of the Flotation of Copper Minerals - COREFlotation of Copper Ores with High Cu/Zn Ratio: Effects of Pyrite on Cu/Zn Separation and an Efficient Method to Enhance Sphalerite Depression by Kosei Aikawa 1,*, Mayumi Ito 2, Nodoka Orii 1, Sanghee Jeon 2, Ilhwan Park 2, Kazutoshi Haga 3, Taro Kamiya 4, Tatsuru Takahashi 5, Kazuya Sunada 6, Taisuke Sakakibara 7, Tatsuhiro Ono 4,Minerals | Free Full-Text | Flotation of Copper Ores with High Cu/Zn ...احصل على السعر
Flotation reagents used in the processing of copper sulfide and oxide ores and their costs are presented. The combined circuit of flotation-hydrometallurgical processing of mixed copper ore at the Udokan deposit is considered. The conclusions reveal the current trends in the processing of copper ores, including the choice of equipment. INTRODUCTIONThis paper focuses on optimizing the parameters of the copper ore flotation process, which is the most expensive in obtaining copper concentrate, in order to improve the copper grade, corresponding to the fine copper law in the copper concentrate and metallurgical recovery, in order to obtain more final tons of fine copper, in the concentrate.Optimizing the Rougher Flotation Process of Copper Oreاحصل على السعر
