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 …
Companies now are also looking to process nickel mined in Indonesia domestically after the Energy & Mineral Resources ministry announced in September 2019 that all unprocessed nickel ore exports, including material over 1.7% nickel content, would be banned from the start of 2020 to increase revenue from the processing of ore.
