Talc has a Mohs hardness of 1, which is naturally crushable and has good grindability. For the fine grinding of talc, various types of Raymond mills are generally used, mainly producing 200 mesh and 325 mesh products. However, if fine grading equipment is installed, products with 500 to 1250 meshes can also be produced.

Talc-chlorite ore bodies consist mainly of talc (sometimes ) and chlorite, which is hydrated magnesium and aluminium silicate. Chlorite is lamellar, soft and organophilic like talc. It is however slightly less water repellent than talc. Talc-carbonate ore bodies are mainly composed of talc carbonate and traces of chlorite.

Introduction. Talc is a naturally occurring hydrous magnesium silicate mineral (US EPA Citation 1992; Fiume et al. Citation 2015).The mineral content, morphology, and purity of talc varies based on the geological conditions under which it is created and its excavation (Drechsel et al. Citation 2018).Talc is classified into two grades.
