Tajikistan has abundant copper–tin resources. In this study, mineralogical analysis of copper–tin ores from the Mushiston deposit of Tajikistan indicates that tin mainly occurred in mushistonite, cassiterite, and stannite, while copper mainly occurred in mushistonite, malachite, azurite, and stannite. The total grades of tin (Sn) and copper …

Gravity Concentration — the separation of minerals by virtue of specific gravity — is one of the oldest forms of mineral processing. Whilst its relative importance has declined in the twentieth century, the high cost of alternative processes, along with the development of a range of high capacity devices has led to something of a renaissance of gravity …

A strong candidate for gravity separation is the recovery and concentration of hematite (ρ 2 = 5000 kg/m 3) from silicates (ρ 1 = 2650 kg/m 3), which in a medium of water (ρ L = 1000 kg/m 3) gives R = 2.4. Hence for most examples of gravity concentration the density driving force for separation is a buoyant density ratio smaller than 2.4.
