The main component of talc is magnesium silicate containing water, with the molecular formula Mg3 [Si4O10] (OH) 2. Talc belongs to the monoclinic system. The crystal is in the form of pseudo hexagonal or rhombic flakes, occasionally seen. Usually formed into dense clumps, leaf like, radial, and fibrous aggregates. Colorless transparent or white, but appearing light green, light yellow, light brown, or even light red due to the presence of a small amount of impurities; The cleavage surface shows a pearl luster. Hardness 1, specific gravity 2.7-2.8.

Talc has excellent physical and chemical properties such as lubricity, anti adhesion, flow aid, fire resistance, acid resistance, insulation, high melting point, inactive chemical properties, good covering power, softness, good luster, and strong adsorption. Due to its layered crystal structure, talc has a tendency to easily split into scales and special lubricity. If the content of Fe2O3 is high, it will reduce its insulation.

Talc is soft, with a Mohs hardness coefficient of 1-1.5 and a sliding sensation. The {001} cleavage is very complete, and it is easy to crack into thin slices. The natural resting angle is small (35 °~40 °), and it is extremely unstable. The surrounding rock is silicified and slippery magnesite, magnesite, lean ore, or dolomite marble. Except for a few moderately stable rocks, they are generally unstable, with developed joints and fractures. The physical and mechanical properties of the ore and surrounding rock have a significant impact on the mining process.
