Publisher Summary. This chapter discusses the exploration, mining, and processing. Once a clay deposit has been discovered, a drilling program to determine the areal extent, thickness and type of overburden, and thickness and quality of the clay is initiated. Both core and auger drills are used in exploration and mine development.

mill is mixed with water and bulk loaded as a slurry for shipping. Figure 11.25-3 depicts the process flow for ball clay processing. Indirect rotary or vibrating grate dryers are used to dry ball clay. Combustion gases from the firebox pass through an air-to-air heat exchanger to heat the drying air to a temperature of approximately 300°C (570°F).

Ball clay is extracted from the ground by surface working (open pit method), underground mining having ceased in 1999. 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 ...

Ball clay is an extremely rare mineral found in very few places around the world. Its name dates back to the early methods of mining when specialized hand tools were used to extract the clay in rough cube shapes of about 30 cm. As the corners were knocked through handling and storage these cubes became rounded and 'ball' shaped.
