GRAVITY CONCENTRATION OF SUDANESE CHROMITE

2011-8-17  Chromite ores are usually concentrated by gravity concentration techniques based on differences in specific gravity between chromite and the common associating gangue minerals and rocks such as serpentine and olivine. Jigging has been used to upgrade a California chromite ore containing 18.1% Cr 2 O 3 to produce a concentrate assaying 43.5% Cr
