This product is a magnesium silicate salt talc group talc. The main component of ultrafine talc is hydrous magnesium silicate.

Commonly used as fillers for plastics and paper products, rubber fillers and anti-adhesives for rubber products, advanced paints and coatings.

The main component of talc is talc containing magnesium silicate with a molecular formula of Mg3 [Si4O10] (OH) 2. Talc is a monoclinic system. The crystals are pseudo-hexagonal or diamond-shaped flakes, occasionally. It usually forms dense aggregates, leaf-like, radial, and fibrous aggregates. It is colorless and transparent or white, but appears light green, light yellow, light brown, or even light red due to a small amount of impurities; the cleavage surface is pearly luster. Hardness 1, specific gravity 2.7 ~ 2.8.

It has excellent physical and chemical properties such as lubricity, fire resistance, acid resistance, insulation, high melting point, chemical inactivity, good hiding power, softness, good gloss, strong adsorption, etc., because the crystalline structure of talc is layered , So it has the tendency to easily split into scales and special smoothness.

The mined talc (the raw material of talc powder) can be directly crushed by using Raymond mill or other high-pressure mill after selecting the good talc. It can be directly packed in a woven bag (50kg or 25kg woven bag) and then sold. In terms of mining methods, due to the extreme instability of the ore and the instability of the surrounding rocks, the ore bodies are mostly inclined and steeply inclined thick and extra-thick ore bodies. The morphology and thickness of the ore bodies vary greatly. Many, in the past, horizontal stratified beneficiative filling mining method was used (some mines still use this method).
