Talc powder characters:
??? 1. Talc is a kind of magnesium-rich layered hydrous silicate mineral. Monoclinic system, usually foliated lamellar, scaly, granular, fibrous aggregate or dense block. The color is white, light green, light gray, light yellow, light brown or pink. Sometimes dyed green, black or dark gray by impurities. Vitreous luster or grease luster, cleavage surface is pearl luster.
??? 2. Hardness 1~1.5, is the lowest hardness mineral, density 2.7~2.8g/cm3. It has smooth feeling and lubricating property. White fluorescence is emitted under ultraviolet irradiation. It has high electrical insulation and thermal insulation, and the refractoriness is as high as 1490 ~ ℃. It is oleophile hydrophobic and adsorptive, insoluble in water and stable in chemical properties.

Production method

Select the extracted talc (talc powder raw materials) and then directly use Raymond Mill or other high-pressure Mill to directly crush the fine talc, and directly use woven bags (50kg, or 25kg woven bags) the finished product can be sold after packaging. In terms of mining methods, due to the extremely unstable ore and the unstable surrounding rock, the orebodies are mostly inclined and sharply inclined thick and extra thick orebodies, and the shape and thickness of orebodies vary greatly, there are many inclusion rocks in the ore body. In the past, the horizontal stratified selection and non-filling mining method was adopted (currently, some mines still adopt this method).
