To start, diatomite mining requires heavy, earth moving equipment. Processing plants which are often large factories need to be in close proximity. Most times, diatomite is mined in open-pit or surface mines where a considerable thickness of the earth is first removed and the purest of the diatomite is exposed. Thereafter, using scrapers, …

Make The Most of Filter Aids
The precoat process involves mixing the filter aid into clear liquid or mother filtrate in a tank. Diatomite filter aids usually work best with a precoat slurry concentration in the 0.3–0.6 wt.% range. This slurry then goes to the filter where the filter medium captures the solids. The clean filtrate returns to the precoat tank.

Diatomite
Diatomite is a hydrous or opaline form of silica, commonly known as diatomaceous earth, diatomaceous silica or kieselguhr. The term "infusorial earth" has lost its original meaning and today is incorrect in view of the distinctions between diatoms and infusoria. Various locality and variety names are obsolete but some retain local significance.
