摘要:Abstract(#br)Alkaline leaching of copper concentrate bearing molybdenite was investigated. Thermodynamic analysis of Mo-S-H 2 O and Cu-Fe-S-H 2 O indicates that alkaline leaching of copper concentrate is feasible for selective extraction of molybdenum. The oxidation mechanis...

摘要:Abstract(#br)The chemical composition of complex inorganic materials, such as copper concentrate, may influence the economics of their further processing because most smelters, and particularly the producers of high-purity electrolyte copper, have strict limitations for the p...

摘要:Abstract(#br)Custom copper smelters impose substantial financial penalties for the presence of deleterious impurity elements in copper concentrates and can outright reject concentrates which contain impurity elements in concentrations that exceed specified values. Hence, there i...

摘要:Abstract(#br)The results of multi-criteria ranking of copper concentrates by their quality, according to their content of useful and harmful components, are presented in this paper. Cu, Ag and Au were taken as useful components, while Pb, Zn, As, Cd, Hg, Bi and Sb were considered...

摘要:... This is causing some concern to copper smelters as they are obliged to dispose of arsenic materials produced as a by-product to the smelting process in accordance with ever tightening environmental guidelines. The onus is to move back to concentrate producers to remove toxi...

摘要:Abstract(#br)The measurement of slurry rheology is a key factor in ore concentrate pipeline design and operation. In addition to the known effects of the input data, the manipulation and the particular conditions of the experimental apparatus may significantly affect the measured...

摘要:Results of studying combined pyrometallurgical processing of relatively high-sulfur, low-copper and high-copper, high-silica sulfide concentrates are presented. Experimental melting of a mixture of highsulfur Aktogai and high-silica Zhezkazgan copper concentrates in the ratio o...

摘要:Abstract(#br)The direct leaching of copper concentrate instead of smelting will be beneficial and gain ground in the future. This paper presents the HydroCopper™ Technology, which is comprised of a chloride-leaching method for copper sulphide concentrates and the copper prod...

摘要:... Using ore and copper concentrate samples from the Olympic Dam mining-processing operation, South Australia, we demonstrate the application of nanoSIMS to understand the mineralogical distribution of potential by-product and detrimental elements. Results show previously un...

摘要:Abstract(#br)Olympic Dam hosts >80 million tonnes of copper, as copper‑iron sulphides, within hematite-dominant gangue. Processing of the relatively fine-grained copper ore is complicated by the presence of by-product uranium and its radiogenic isotopes, in particular 226 ...
