WebOnce mined, corundum can be separated from clay and gravel because it is more dense and heavy. Usually, the gravel is broken up and sorted into size fractions in a rotating drum (trammel), and then washed either by hand or with a high pressure water jet, over filters with various size holes. WebOlivine usually only occurs as part of a rock mass, but when it does form recognizable crystals these are transparent to translucent, olive-green crystals that typically have a granular shape. Minerals in the Olivine Series are quite hard, falling from 6.5 to 7.0 on the Mohs hardness scale.

The phlogopite commonly contains small elongate needles of apatite. WebIt either occurs as monomineralic veins or is associated with albite, glaucophane, aragonite, lawsonite, and quartz in high-pressure, low-temperature metamorphic rocks of blueschist facies.
