Chrome ore flotation Generally, when the gravity separation and magnetic separation fail, flotation offers an alternative technique to concentrate the fine-grained and ultra-fine-grained chromite rocks and fine-grained chromite tailings which require fine grinding for liberation. But grinding will produce a large amount of ore slime.

Usually, chromite ore enrichment is carried out by using gravity separation due to high-concentration criterion between chromite and other minerals. However, chromite ore from Sukinda region, India, is a typical ore body with high iron content in the chromite spinel as well as gangue content in the form of oxide and hydroxides of iron …
