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.
Abstract: This is an article in the field of mineral processing engineering. The study objects are a spodumene waste rock in Sichuan. According to the mineral characteristics of thisspodumene waste rock, heavy medium separation tests were carried out at three different feed particle sizes (-15+0.5 mm, -10+0.5 mm, -5+0.5 mm) of the spodumene waste rock in …

How it works
The Dense medium separation (DMS) or heavy medium separation (HMS), or Sink-Float gravimetric separation, also known within the field of the scrap treatment as Flotation, is a process used to separate materials that have different specific weight. To obtain this kind of separation, the material to be separated is immersed into a 'bath' of a ...
Dense medium separation | Machines
However in the Ad Rem bi-directional design, the medium together with solids is injected over a large separation zone, making it almost impossible to bury floats with sinks. 2. The stability of the medium. A typical dense medium bath is relatively deep, and this makes it difficult for the suspension particles to remain in suspension.
