翻译此页OverviewCopper Concentrate Enrichment Process
Most copper ore currently being mined contains copper mainly as chalcopyrite. Since chalcopyrite by itself is only about 35 percent copper, it is difficult to upgrade a concentrate by flotation to more than about 25 to 28 percent copper without losing a significant amount of copper during the cleaning steps. Some ores have associated problems such as chalcocite-coated pyrite and are difficultОнлайн-запрос
Copper and Pyrite Separation by Selective and Sequential
