Tin Ore Flotation Process - JXSC Mining

At present, tin used in industry mainly comes from cassiterite. Because the density of cassiterite is relatively high (6.4~7.1g/cm3), the primary method of beneficiation of cassiterite is reselection. However, because cassiterite is brittle, it is simply siltified in nature and in the process of crushing, grinding, and beneficiation.

The beneficiation of iron tailings by flotation poses more challenges than iron ore beneficiation. The challenges are mostly due to the fine particle size of the tailing, which falls below the optimal range for flotation (<10 μm). Also, the presence of slimes creates selectivity problems by coating the particles.
