Cassiterite is a tin oxide mineral, SnO2. It is generally opaque, but it is translucent in thin . Hydraulic mining methods are used to concentrate mined ore, a process which relies on the high specific gravity of the SnO2 ore, of about 7.0.
The brief history of mining for cassiterite and columbite in the Study area as . both tin and columbites, using their difference in specific gravity, the processes are; .. On extraction of the material, it is buretted, the purity (grade) is scaled at 18.0.
