Cassiterite is the prime economic tin mineral that occurs in alluvial and hard-rock deposits. The existing literature on cassiterite beneficiation is mainly focused on gravity concentration and flotation techniques. In addition, a few published articles discuss the ultra-fine particle processing techniques such as selective flocculation, shear ...

Cassiterite is a widespread minor constituent of igneous rocks. The Bolivia veins and the old exhausted workings of Cornwall, England, are concentrated in high temperature quartz veins and pegmatites associated with granitic intrusives. The veins commonly contain tourmaline, topaz, fluorite, apatite, wolframite, molybdenite, and arsenopyrite.
