Chromite is concentrated mostly with shaking tables and spirals. Flotation can be considered as a leading process to beneficiate the fine chromite which cannot be enriched by gravity separation. Because of the complex nature of chromite and olivine which is the most abundant adjoininig mineral, the type of collector is very important in this flotation. After examination of the effect of sodium oleate on chromite and olivine by adsorption studies and electrokinetic mobility measurements, sodium oleate and other anionic collectors were used in the chromite flotation. Flotation results showed that some special collectors such as modified fatty acid and alkyl phosphate are more effective on the separation of chromite from olivine.
