What is Pyrophyllite? Trinity Resources Talc and

Talc and pyrophyllite are platy belonging to the same phyllosilies subclass of minerals. The weak Van der Wall forces which separate the platelets, aids in the delamination of these minerals and platelet structure retention during processing. Trinity''s pyrophyllite is macro crystalline with a high aspect ratio.

Soapstone Wikipedia

Soapstone (also known as steatite or soaprock) is a talcschist, which is a type of metamorphic rock.It is composed largely of the magnesium rich mineral talc.It is produced by dynamothermal metamorphism and metasomatism, which occur in the zones where tectonic plates are subducted, changing rocks by heat and pressure, with influx of fluids, but without melting.

Re: Pyrophyllite Clay does not deplete minerals, it adds

HarmonicCharge, Bentonite may deplete your minerals, but pyrophyllite will not. Its rich amorphous silica content insures that minerals are more bioavailable to your system. It also creates, in combination with water, orthosilicic acids which are extremely beneficial to your health. Amorphous silica is also helpful in reducing heavy metal content in the body.
