- Jaw Crusher Flotation Separation Froth
Froth flotation is a common mineral processing technique that is used to remove low economic gangue minerals, such as pyrite, from ore. The main hydrophilization mechanism on the pyrite surface is explained by the formation of hydrophilic iron (Fe) hydroxide and its complexation with calcium (Ca) and magnesium (Mg) ions; however, …

The core samples were initially crushed to −3 mm using a laboratory jaw crusher for the flotation feed sample preparations. The crushed particles were further ground using a laboratory ball mill to two main-sized fractions of −150 (d 80: 92) and −38 (d 80: 28) µm for the different flotation practices. The respective samples were ...

The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In …

The treated ore pulp goes into the flotation cells for mixing and pneumatic, making the aimed mineral suspended and generates lots of froth. During the cotact of aimed mineral and the froth, the ore particles with good floatability are selectively attached to froth, and the froth float up to the pulp surface to form a mineralized froth layer.
