Beneficiation of Copper Sulfide by Flotation. Copper, due to the present world demand and price, is of foremost interest to the mining industry. Many new properties are either in the process of being brought into production or are being given consideration. Copper minerals usually occur in low grade deposits and require concentration prior to smelting. The,Syama - Resolute Mining,Syama is a large-scale operation which comprises two separate processing plants: a 2.4Mtpa sulphide processing circuit and a 1.5Mtpa oxide processing circuit. The sulphide circuit comprises three-stage crushing, milling, flotation, roasting, calcine leaching and elution with ore sourced from the Syama Underground Mine and stockpiles. The oxide circuit comprises conventional crushing, SAG,Leaching of Copper Sulphides - SAIMM,pyrometallurgical processing route of copper sulphides. Three copper sulphide leaching and refining processes are discussed: total pressure oxidation, ferric sulphate leaching and copper chloride leaching. The effect of mineralogy on the choice of processing technology is discussed as well as some of the unit processes used. Additionally, possible benefits that a hydrometallurgical process may,Syama Gold Mine - Resolute Mining,sulphide processing circuit and a 1.5Mtpa oxide processing circuit. Mining at the main Syama open pit was completed in May 2015 with ore for the sulphide circuit currently being sourced from previously stockpiled sulphide ore, underground ore from the new sub level cave mine and satellite operations. Ore for the oxide circuit was supplied by series of satellite deposits in FY18 and will be,Sulfide Ore - an overview | ScienceDirect Topics,For sulfide ore processing, nickel has to be separated from the iron present in the sulfide concentrate. This is conventionally done in both the smelting and converting stages. To aid iron rejection in the smelting stage, the concentrate is first partially roasted to oxidize the iron sulfide. This is done either in a multiple hearth roaster or in a fluid-bed roaster. During partial roasting in,
Mineral Processing - KCGM
The sulphide ore from the Open Pit is refractory and requires a complex series of processes to extract the gold. The free-milling Mt Charlotte ore, which is easier to process, was formerly direct-leached after grinding but is now combined in small batches with the Fimiston sulphide process.
