20221117In laterite nickel raw material, iron is the most dominant element in the preparation of laterite ore, which is 80.637%. During the nickel laterite extraction process for the precursor solution, the nickel and the iron element will also be extracted. This will have an undesirable effect and affect the purity of the nickel oxalate precipitate.

13.12.2018The smelting of nickel laterite ore is no different, as the smelting process is the dominant technique and is typically used to make nickel pig iron (NPI) for the Chinese stainless steel market. NPI is created by mixing, saprolite ores with coking coal and a mixture of fluxes. The process culminates in an electric arc or blast furnace, which
