    Historically, china clay mining resulted in the release of both coarse sand as bedload sediment within rivers and also some fine china clay being released in suspension. The early working of china clay was by hand, the river sediment was removed, and then diverted river water was used to separate the coarse sand from the clay, fine sand and mica; a process referred to as ''breaking in the stream''.
