[PDF] Talc and pyrophyllite

The mineral talc is a hydrous magnesium silicate. A massive talcose rock is called steatite, and an impure massive variety is known as soapstone. Talc is used commercially because of its fragrance retention, luster, purity, softness, and whiteness. Other commercially important properties of talc are its chemical inertness, high dielectric strength, high thermal conductivity, …

TALC BENEFICIATION Filed Sept. 18, 1959

beneficiation have been employed to remove impurities from the talc and not to separate one form of talc from the other. As a result, the final beneficiated talc product still contained substantially the same proportion of gran ular and fibrous talc to platy talc that it contained prior 45 talcum powders of the most lubricous nature, but the ...

Talc Flotation—An Overview

Talc with a theoretical chemical composition, Mg 3 Si 4 O 10 (OH) 2, is the softest mineral on Earth, mainly attributed to its chemical structure.The magnesium-based octahedral layer is in between silica rings through shared oxygen atoms. This exposes oxide surfaces that make talc only held together by weak van der Waals forces.
