Dense Media Separation (DMS) Plants
Dense Media Separation. A heavy medium is a heavy-fluid or heavy suspension fluid with a density greater than that of water (1g/cm3). The process of separating ore particles in heavy media is called Dense Media Separation / Heavy Media Separation (DMS / HMS). The heavy medium separation method is an advanced gravity beneficiation method.

The flotation of auriferous pyrite with a mixture of collectors
Pyrite is considered as a gangue mineral and generally is not desirable in the processing of sulfide ores, nor in coal cleaning operations [5–8]. However, pyrite is recovered and taken as a concentrate when it contains valuable elements such as gold (Au), silver (Ag) etc. [7,9–12].

Froth Flotation of Chalcopyrite/Pyrite Ore: A Critical Review
Natural chalcopyrite has a molecular weight of 183.5 g/mol, with a theoretical composition of 34.6% Cu, 30.4% Fe, and 34.9% S. This mineral has a brassy yellow color, often with an iridescent tarnish, including a bronze color. Sometimes it occurs with a surface layer that gives various bright shades due to oxidation.
