Introduction

Talc is a naturally occurring hydrated magnesium silicate mineral and is recognized as the softest mineral on Earth (Mohs Hardness 1). It is widely used in plastics, paints, paper, ceramics, cosmetics, pharmaceuticals, rubber, agriculture, and construction.

Geological Formation

Talc forms through hydrothermal alteration and metamorphism of magnesium-rich rocks over millions of years.

Mining Locations

Major deposits are located in Sherwan, Jamrud, Mohmand, Bajaur, Shangla, Swat, Chitral, Buner, Zhob, and Khuzdar.
