What is Ball Clay | The Kaolin and Ball Clay Association

Extraction involves excavators and dump trucks to selectively remove individual grades of clay to storage and blending facilities. The ratio of waste to clay is variable, but overall is in the order of 1 to 1.5. Ball clay undergoes limited processing. Most is size reduced and some 70% is sold in this form.

How Is Clay Mined And Processed

The initial processing of mined clay involves cleaning and removing impurities to enhance its quality and purity. The clay is first crushed into smaller particles to facilitate the removal of impurities. Screening or sieving techniques are then employed to separate larger particles, rocks, and debris from the clay.
