Soapstone - Wikipedia

Soapstone (also known as steatite or soaprock) is a talc-schist, 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.

This milling is also effective for economically grinding materials in the 2 to 30 micron dv50% range. This milling can be performed in an aqueous or solvent based slurry.

Particle Sizes - Engineering ToolBox

The size of contaminants and particles are usually described in microns, a metric unit of measure where. one micron is one-millionth of a meter. 1 micron = 10-6 m = 1 μm. In imperial units. 1 inch = 25400 microns. 1 micron = 1 / 25400 inch. The eye can in general see particles larger than 40 microns. Typical size of contaminants and particles ...

Talc Milling - Hosokawa Micron Powder Systems

Talc Milling. Talc is a clay mineral made of hydrated magnesium silicate. Talc is formed from metamorphic reaction of minerals in aqueous conditions. Talc is one of the softest minerals on earth, with a Mohs hardness of 1.0 (defining mineral). However, some abrasive impurities (such as quartz or sand) may be present in the mined talc.
