Efficient particle separation with heavy-media cyclones

A heavy-media cyclone is a type of separation equipment used in the mineral processing industries to separate minerals from gangue based on density differences. The use of a dense medium, such as magnetite and/or ferrosilicon, forms a pseudo-fluid with a higher relative density than water, which establishes the separation process. ...
