Due to the high density of cassiterite (6.4~7.1g/cm3), gravity separation is often used to process cassiterite. However, cassiterite is easily sludged in the nature and in the process of ore sorting. Therefore, flotation is also used to recover fine-grained cassiterite from the fine mud and tailings. 1. Why is tin oxide ore extraction so ...

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 (6.4~7.1g/cm3), the primary method of beneficiation of cassiterite is reselection.

In this way the magnetic and nonmagnetic particles in the ore are separated because of their magnetic nature. For example, cassiterite is a tin ore. It contains mainly the nonmagnetic ingredient stannic oxide (SnO 2) and the magnetic ingredient ferrous tungstate (FeWO 4). These are separated by the electromagnetic method.
