Most domestic clay is mined by open-pit methods using various types of equipment including draglines power shovels front-end loaders backhoes scraper-loaders and shale planers. In addition some kaolin is extracted by hydraulic mining and dredging. Most underground clay mines are located
Underground specialized mining equipment such as trucks loaders diggers etc. are used to excavate the material and are normally hauled to the surface with skips or lifts for further processing. Drilling is normally required to place explosive charges to liberate the minerals from the overburden material.
A clay pit is a quarry or mine for the extraction of clay which is generally used for manufacturing pottery bricks or Portland cement. Quarries where clay is mined to make bricks are sometimes called brick pits. A brickyard or brickworks is often located alongside a clay pit to reduce the transport costs of the material.
The process begins in the vast open cast mines located across central Cornwall. The Mining operations use two different methods either ‘wet’ or ‘dry’ to extract the material. In ‘wet’ mining the clay is liberated by high pressure hoses and processed from a slurry.
The following classification therefore seems the most logical and is the one generally used by placer miners: Hand-shoveling; ground-sluicing; hydraulicking; excavating by teams or power equipment; dredging; drift-mining. Combinations of methods 1 2 3 and 4 may be used and one method may graduate into another.
