Talc originates from talc, which is a metamorphic mineral that is widely distributed in crustal rocks, especially metamorphic rocks.

Since talc is often dispersed in rocks, all talc-containing rocks cannot be used as a source of talc at present. Only in a favorable geological environment, when the talc minerals are abundant in a certain area, and the quantity and quality reach the current economic and technical conditions for mining, it is called a talc deposit.

Talc deposits can be composed of one or several talc ore bodies, each talc ore body has a certain shape, size and occurrence, and is the object of our actual mining, which can be used to make talc powder.
