China Clay Kaolin Clay Deposits in Pakistan and Uses In Industrial

China clay, also known as kaolin clay, is a soft, white, clay mineral with the chemical composition Al2Si2O5(OH)4. It is a hydrous aluminum silicate that belongs to the kaolinite group of minerals. China clay is named after the country where it was first discovered, which is China. It is one of the most common clay minerals and is widely used in various industrial applications.

China Clay Deposits in Pakistan:

As of my last knowledge update in January 2022, Pakistan has significant deposits of china clay, and the mineral is found in various regions. Specific details about the extent and quality of these deposits may require reference to more recent geological surveys and reports.
