diatomite processing worldwide

The applicability of cold sintering to diatomaceous earth was explored. Diatomite powder can be densified above 90% of the theoretical density when the process is carried out at 150°C under 300 MPa in a caustic environment (3-M NaOH water solution). Such density value is similar to those achieved by conventional sintering at 1200–1300°C.

Diatomite is usually mined in open-pit, surface mines. A considerable thickness of earth, known as overburden, may have to be removed. Once this layer is removed and the purest of the diatomite strata is exposed, it is then cut from the bed with powerful scrapers and stockpiled. The stockpiled material is then hauled to the processing plant

Diatomite. Diatomite is a powdery mineral composed of the fossilised remains of microscopic single-celled aquatic plants called diatoms. Diatoms can uniquely absorb water-soluble silica to form a highly porous, yet rigid skeletal framework of amorphous silica. Diatomite is light, rigid, exceptionally porous, absorbent and pure.

The French company's Lompoc mine and processing facility, which formerly belonged to World Minerals and is one of the world's largest sources of diatomite, has been ordered to pay $350,000 in civil penalties, implement environmental rectification measures and submit to regular inspections after it allowed diatomaceous earth slurry to leak ...
