(57) Abstract: Usage: mineral processing, in particular flotation of copper-zinc sulphide ores and products. Method of flotation of sulfide copper-zinc ores includes the conditioning of the pulp in a calcareous environment with reagents-regulators sulfur, sodium, and zinc sulfate, the introduction of collector and Frother and subsequent separation with separation of copper minerals in theLearn More
To obtain a better understanding of the process, calculations were performed by Dinsdale et al. (1988) and Taylor and Dinsdale (1990) for a pre-fused matte of Ni 3 S 2, Cu 2 S and FeS, heated to around 1270°C with an equivalent amount of oxide slag, and with O being blown into the matte. Calculations from the model system Cu-Fe-Ni-S-O are presented in Fig. 10.78 which shows the comparisonLearn More

The Inco process, the Outokumpu Oy process, and the Sheritt Gordon process are primary methods for nickel production from sulfide ores. Nickel briquettes and nickel powder by sulfuric acid leaching, ferronickel pigs by direct reduction, nickel rondelles from matte and nickel oxide sinter by reductive roast and ammoniacal leaching are primary processing schemes for oxide oresLearn More
Ep can be measured using a gold sensing electrode or a mineral electrode. The main reason why platinum "can't" sense what's happening on the mineral surfaces is because of its electro-catalytic activity for the oxygen reduction reaction. If one desires to know how the sulphide minerals "feel", either uses a mineral electrode or a gold electrodeLearn More
