Diatomite from Dai Lao valley, in Lam Dong province was selected for investigation of its possible appliion in preparation of filter aids. For this purpose, diatomite ore was leached in acids to enrich SiO2 and reduce impurities, and then calcined at high temperatures in order to improve the material characteristics for use in filtration.
Facts about Diatomaceous earth, also called diatomite or Kieselguhr. ... When processed at proper temperatures, the crude ore pops in a manner similar to popcorn. ... Perlite Filter Aids are amorphous in their structure, thereby not dangerous to human beings.
The production of diatomite products is difficult and complex. It requires large processing facilities and heavy earthmoving equipment. EP Minerals operates four facilities for the production of diatomite products, three in Nevada and one in eastern Oregon. The ore is first surfacemined.

· · This method was selected due to high ratio of very fine primary diatomite particles (1–5 μm) in dried semiproduct. The fine particles decrease the flux because of high resistance to flow. Hence, it is necessary to provide size distribution of the filter aids particles that have its maximum in the range of 5–40 μm.
