This way an easy separation of the minerals can be achieved. LST and SPT are cleaned and recycled after their use. DIM (diiodomehtane) has a very high density (3.325g mL-1) and helps to separate the heavy minerals which were part of the heavy fraction during LST or SPT treatment. In our case, DIM helps to separate apatite from zircons.

Refractory - Wikipedia

A refractory material or refractory is a material that is resistant to decomposition by heat, pressure, or chemical attack, and retains strength and form at high temperatures. Refractories are polycrystalline, polyphase, inorganic, nonmetallic, porous, and heterogeneous. They are typically composed of oxides or non oxides like carbides, nitrides etc. of the following materials: silicon ...

Heavy media separation with dense Magnetite LKAB Minerals®

Principles of heavy media gravity separation. Heavy media gravity separation means separating products with different densities. Both magnetite and water are used to make a slurry on which one product will float (the product with a lower density than the slurry) and in which the other product will sink (the product with a higher density than the slurry).
