How to Extract Tin from Tin Oxide Ore?

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.
