Oct 16, 2021 2021-10-16 by JXSC Mining. There are more than ten kinds of tin-bearing mineral deposits. At present, tin used in industry mainly comes from cassiterite. Because the density of cassiterite is relatively high (6.47.1g/cm3), the primary method of beneficiation of cassiterite is reselection. However, because cassiterite is brittle, it is simply siltified in nature and in the
