Classification of Silicate Minerals

The chemical name for the substance of quartz is silica; and any mineral that is composed in part of silica is a silicate. In the Classification of Silicate Minerals and the study of minerals and rocks, silica is called an acid; in silicates, the substances other than silica are called bases, for example, lime, potash, and soda. When giving the full name of a silicate the names of these bases ...

What is Talc? - Industrial Minerals Association - North ...

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 more hydrophylic. Talc-carbonate ore bodies are mainly composed of talc carbonate and traces of chlorite.

Chrysotile - Wikipedia

Chrysotile or white asbestos is the most commonly encountered form of asbestos, accounting for approximately 95% of the asbestos in the United States and a similar proportion in other countries. It is a soft, fibrous silicate mineral in the serpentine subgroup of phyllosilicates; as such, it is distinct from other asbestiform minerals in the amphibole group.
