Vermiculite may have no asbestos or have trace amounts, which poses a low health risk to home gardeners who use it infrequently. To minimize risk, reduce the amount of dust emitted, which can be irritating. To prevent this, use vermiculite outdoors or in a well-ventilated area, dampen it when using, and avoid getting the dust on your clothes.

Only the first two are done at Shava mine. Exfoliation is a technologically simple process however it is not conducted once exfoliated, vermiculite increases in volume by between 15 and 20 times and becomes very fragile. This greatly increases transportation costs and makes the beneficiation of vermiculite unfeasible.

Talc remains an important mineral with a wide array of applications in paints, paper, polymers, pharmaceuticals, and cosmetics industries when its associated impurities were accordingly processed due to its distinct surface properties. Thus, treatment of a Nigerian talc ore consisting of talc, vermiculite, and phillipsite was investigated using polyethylene glycol (PEG …
The beneficiation studies of Suresh (1981) illustrate that low-grade chromite ore of 16%–25% Cr 2 O 3 of Sitampundi area of India, cannot be upgraded by using conventional physical beneficiation techniques like gravity and flotation, due to the intimate association of iron in the lattice of chromite particle. However, they have demonstrated ...
