FluxCalcined Diatomaceous Earth · Dicalite Management Group

Fluxcalcined diatomaceous earth is processed and purified in a rotary kiln in the same fashion as our calcined diatomaceous earth with the addition of a natural fluxing agent to further increase agglomeration. Because of its higher permeabilities, it can be used to remove impurities at very high filtration flow rates.

Dolomite Mineral Uses and Properties

The most common use for dolostone is in the construction industry. It is crushed and sized for use as a road base material, an aggregate in concrete and asphalt, railroad ballast, riprap, or fill. It is also calcined in the production of cement and cut into blocks of specific size known as "dimension stone."
