quartz separation from gypsum

Separation and identification of minerals from Northern Great Plains .Minerals were separated from nine lignite samples on the basis of specific gravity differences by float/sink of fine particles in carbon tetrachloride. Examination of the sink fractions showed the presence of nacrite, barite, pyrite, hematite, quartz, calcite, gypsum, and fragments of a mixture of α-quartz and nacrite. No separable.Separation and identification of minerals from Northern Great Plains .Minerals were separated from nine lignite samples on the basis of specific gravity differences by float/sink of fine particles in carbon tetrachloride.

Crain's Petrophysical Handbook - Visual Analysis Of Lithology .

Sand – shale identification from gamma ray and density-neutron separation. Small amounts of density neutron separation with a low gamma ray may indicate some heavy minerals in a sandstone. Most minerals are heavier than quartz, so any cementing materials, volcanic rock fragments, or mica will cause some separation.

quartz separation from gypsum,Uniaxial Minerals Interference Figure

OPTIC SIGN DETERMINATION. Once the interference figure has been obtained and identified as to whether it is uniaxial or biaxial, the optic sign of the mineral can be determined using an accessory plate, either gypsum, quartz or mica. The optic sign tells us whether the ordinary ray corresponds to the fast or slow ray.
