Upgrading nickel in laterite ores by flotation - ScienceDirect

2018-6-1 · In this study, upgrading nickel by flotation in three laterite ore samples, limonite, saprolite and intermediate, from different geology zones, was investigated. It was possible to upgrade the nickel grade in the saprolite sample by about 40% at more about 70% recovery using a hydroxamate collector at pH 10.
