The effect of inorganic acids on reducing iron impurities during iron-rich laterite ore leaching [PDF]
International Journal of Mining and Geo-Engineering, 2021 The Recovery of nickel from lateritic ores as the main oxide resources has been always debated. Since it consists of 1.74% Ni, 0.14% Co and 40.8% Fe, co-dissolution of iron occurred by using common lixiviation like sulfuric acid. Therefore, some leaching
