1. Copper-nickel sulfide ore beneficiation. When the nickel content is more than 3%, it is a rich ore, which can be directly smelted;; When the nickel ore content is less than 3%, it is mainly accompanied by a large amount of metal mineral (pyrrhotite, pentlandite, chalcopyrite)and gangue minerals (olivine, pyroxene, plagioclase, talc, mica, quartz, etc.);
The reduction roasting ammonia leaching process (RRAL) originally defined by Caron (1950) has been extensively applied to treat low grade nickel laterite and a large amount of slag-containing some valuable metals, has been generated and accumulated over the years since then. However, there are no reports on how to utilize it …
It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 °C. Iwasaki et al., (1961) and …

(1). Copper in copper-nickel sulfide ore mainly exists in the form of chalcopyrite, and nickel mainly exists in the form of free nickel sulfide such as fennelite and pentlandite. In addition, most of the nickel is mainly endowed in pyrrhotite in the form of similar phenomena, so the most important process of beneficiation of copper-nickel …
High nickel matte is a common raw material in both nickel refining methods (i.e., GFEM and LEM). More high nickel matte inputs in the refining stage lead to a higher environmental damage in the nickel mining and beneficiation stages and the pyrometallurgical stage. 3.3. Identification of key factors
