Diatomite ore is primarily composed of silica, which undergoes refinement through calcination at various temperatures. The ore used in the production of filter aids originates from deposits formed from the fossilized remains of diatoms, a type of plankton found in lakes and oceans. These single-celled organisms develop cell walls, known as frustules, composed of silica absorbed from the surrounding water during nutrient uptake. The accumulation of fossilized diatom frustules leads to the formation of diatomite deposits, which serve as the raw material for processing.
Diatomite deposits can be found worldwide, but their size and quality determine their suitability for filter aids processing. Only a limited number of deposits globally meet the necessary criteria, making them viable for manufacturing various products. Some of these deposits were formed between 100,000 to 10 million years ago, providing a diverse range of raw materials for production.
