Hydrophobic agglomeration flotation of fine cassiterite …
Cassiterite is the most economically valuable tin mineral in nature and also the main source of tin production. In China, the process of gravity separation combined with flotation is often used to recover cassiterite in industry, but the average recovery is about 70%, and the 30% cassiterite is lost in tailings in the form of fine particles [4].

New insights into the mechanism of selective flotation of copper and
Flotation is commonly used to separate and recover minerals from gangue. Here, flotation was used to separate copper from copper-tin alloy. Vibration mill was used in the fine crushing process of materials. During the flotation process, the froth product is copper, and the material sinking to the bottom of the flotation cell is solder.
