The proponent is proposing to install a processing facility at its existing mine site that would separate mined and stockpiled ore into various products. The processing facility would allow a complete reclamation of existing stockpiles and would eliminate future stockpiles from being created during mine development.
Moreover, pyrophyllite helps film dry and promotes good dispersion. The main properties of pyrophyllite exploited in the paint industry as an extender are the mineral's high refractive index, platy structure, softness, smooth surface, white color, chemical inertness, mechanical strength, and pearly luster. ... These techniques are discussed ...
How to process High-Purity Pyrophyllite Powder? High-grade pyrophyllite powder is obtained by purifying low-grade pyrophyllite. This high-grade powder is a valuable, expensive product used in refractory materials, ceramics, and electronics. Currently, the price of pyrophyllite powder with about 27% Al 2 O 3 can reach US$480/ton.

Pyrophyllite demonstrates good tolerance to strong acids and alkalis due to its electrical neutrality and chemical inertness [14]. Furthermore, it exhibits notable oil absorption ability and has a refractive index between 1.55 and 1.60 [15]. Pyrophyllite is mostly produced in Korea, Japan, India, Thailand, Saudi Arabia, Peru, and South Africa [16].
