Abstract
The processes involved in treatment and processing of copper and nickel ores with the use of phosphoric acid solutions are investigated, as well as processes of precipitation of platinum metals with thiocarbamide and sorption of nickel and cobalt from phosphoric solutions. A technology is proposed for co-processing of copper and nickel ores from Noril'sk deposits and the apatites from Maymecha-Kotuy province. Advantages of this technology are: isolation of all valuable components from raw material in the form of high-quality primary concentrates, decrease in the amount of recycling products due to simplification of the technology, high coefficient of multipurpose utilization of raw material, which provides manufacture of additional products, absence of the necessity for expenses to build tailing and cake dumps, sulphur utilization in Clause process, which provides a decrease in environmental hazard, simplicity of instrumentation, simultaneous production of phosphoric fertilizers for the needs of agriculture in Siberia.
