Four Points To Improve Tin Ore Flotation Recovery Rate

 — Tin ore is also known as cassiterite. As a kind of ore with high density and fine particle size, the traditional beneficiation process cannot recover tin ore, so new methods must be found. However, flotation is an effective means to recover the fine-grained tin minerals from tin ore to tailings.

Gravity Concentration Methods

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 …

Cassiterite

Cassiterite is a mineral composed of tin dioxide (SnO2) and is the primary ore of tin. It is generally brown or black in color and has a high density, making it easy to identify. The mineral can be identified by its hardness, which is 6 to 7 on the Mohs scale, and its luster, which is adamantine to submetallic.

LECTURE NOTES

The crude ore from the mines contain a number of solid phases in the form of an aggregate. The valuable portion of the ore is known as mineral while the worthless portion is known as gangue. During ore dressing, the crude ore is reduced in size to a point where each mineral grain becomes essentially free so as to make separation between them.
