When considering the environmental impact of mining on the Fal Estuary, the most important quarrying activity was the production of china clay (kaolinite), principally from the St, Austell area. 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.

We perceive this as a viable way of working with minerals and replacing the very dirty aspects of mineral processing, he says. Apart from reducing the processes' environmental impact, this approach can significantly reduce the energy required to extract desired components from ores, such as the increasingly valuable rare earths used in a variety of high-tech devices.
