2020-5-7This process is used for the extraction of copper from low grade sulfide ore. In this process the crushed and ground ore in bulk about 100000 tons is exposed to air and water in big tanks. The air in the presence of water gradually oxidies copper and iron sulphides to their surphides. The process is completed in about one year

2019-11-7Nickel Ni is naturally present as two principal ore types approximately 60 in sulfides and 40 in laterites 1. Most of nickel production is derived from sulfide ores 2. The main reason is that the laterite ores require more extensive and complex treatment for nickel extraction 34. Compared to sulfides laterite processing

A low-grade disseminated nickel sulphide serpentinite ore from W.A. had a relatively high permeability after drying. Various techniques indicated that the permeability resided within a fine network of fibrous vein- lets and especially within coarse cracks along which the sulphides lay. The ore minerals were therefore open to selective extraction by chemical leaching
