MLA results revealed that sulfide minerals constitute around 15-20% of the flotation feed. A large portion up to 70 to 80% of the feed consists of gangue minerals. Dolomite is the main gangue rock and needs to be separated from the valuable minerals. The second most abundant gangue mineral is pyrite which constitutes about 1-2% of the feed weight.

Relative density - Wikipedia
Relative density, or specific gravity, is the ratio of the density (mass of a unit volume) of a substance to the density of a given reference material. Specific gravity for liquids is nearly always measured with respect to water at its densest (at 4 °C or 39.2 °F); for gases, the reference is air at room temperature (20 °C or 68 °F). The term "relative density" (often abbreviated r.d. or ...

The muscovite ore used for flotation experiments was obtained from a muscovite mine. In order to obtain a size fraction small enough for zeta potential measurements the muscovite ( d50 = 20 μm) was passed through a 2″ Mozley hydrocyclone with a cut size of approximately 10 μm and operating pressure of 35 psi.

Halite | Common Minerals
Since it forms primarily from evaporation, halite normally is found with other evaporation-associated minerals such as calcite, gypsum, anhydrite, and sylvite. Sylvite, although rare, is poisonous - so it is a good idea to use your finger to test an unknown sample's taste, rather than directly licking the sample.
