Abstract Scope |
In order to comprehensively utilize Jinchuan nickel ore resource, an innovative process of flotation – high-pressure oxidation leaching was developed. The process first produced high-quality concentrates (high-nickel and low-magnesium) for nickel flash smelting furnace; then it treated the flotation intermediate product (nickel-containing pyrrhotite concentrates) with oxidized leaching at high temperatures to solubilize the remaining non-ferrous metals in the solution. Magnesium thiosulfate was used to precipitate copper and nickel separately from the leaching solution. A high quality magnesium (by-product) was ultimately obtained from solution purification and crystallization. This paper will report the study of froth flotation that include mineralogy study and chemical reagent experimental tests. The lab and pilot flotation tests and the results will also be presented. |
