The production of marketable, high-grade talc products demands a separation of talc from other minerals, which are present in the run-of-mine material. Most talc deposits are based on Mg-rich ultramafic rocks or on carbonates. Talc is formed by hydrothermal addition of silica and hydroxide ions to those two types of host rock.

2. Talc is used as mineral filler in various industries to reduce production cost and/or gain new properties. As example, for its high thermal stability, talc is used as a refractory material in kiln furniture; for its neutral electric charge, it is used as an electrical and thermal insulator material in composites. For its platy shape,
Talc is hydrated magnesium silicate (Mg 3 Si 4 O 10 (OH) 2); however, it may contain mineral impurities such as chlorites and fibrous amphiboles, calcite, magnesite, and dolomite.Talc has a characteristic perfect-basal exfoliation known as lamellarity or platiness due to low- to moderate-grade metamorphism during its formation.
The Mineral talc. Talc is known for being the softest mineral on earth. It is number 1 on the Mohs hardness scale, and can be easily scratched by a fingernail. Talc is not commonly seen in collections, as it is usually uninteresting and fairly common, although a few deeply colored and crystallized examples are known and well sought after.
