The objective of flotation studies was to improve the overall chromite recovery by flotation of chromite in the slimes from the gravity concentration circuit. Smith showed that an ore containing serpentine as the primary gangue mineral was amenable to concentration by flotation using a cationic collector with the pH modified to below 2.5 with ...

The Bureau of Mines, U.S. Department of the Interior, devised a flotation technique for upgrading chromite in chromium ores and gravity concentrates. The technique consisted of cationic flotation of chromite from a slime-free pulp acidified to ph 2.5 Or lower using h2so4 modifier. Flotation results showed that ore containing serpentine as the primary gangue mineral was more amenable to concentra

During chromite mining, nearly 10 t of waste overburden, containing on average 0.5% Ni, 0.02% Co and 25% Fe, are currently being rejected for every tonne of chromite mined. The nickel in such waste materials is found to be in association with goethite, which is the predominant iron mineral and tends to become enriched in the fines along with iron.
