Diatomite Mining and Processing

Diatomite Mining and Processing. The mining and processing of diatomite is delicate and complicated. It requires large processing facilities and heavy earth moving equipment. To minimize costs, diatomite is usually mined in open-pit, surface mines (although some operations do use underground extraction methods).
