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.
— 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.
