Solvent Extraction Process for the Recovery Cobalt and ...

Low-grade laterite which contains nickel lower than 0.5% is difficult to be processed using pyrometallurgy. One method which is able to solve this problem is solvent extraction. In this study, a solvent extraction process using batch recycle methods has been successfully applied to separate nickel and cobalt from low-grade laterite.
