Diatomite Mining and Processing

Diatomite does not need to be blasted as it is a soft, friable ore. For most applications, the ore is then either calcined or flux calcined in a large rotary kiln to agglomerate the diatoms and produce the desired grade. This is a highly energy intensive process. The ore is heated to temperatures in excess of 1800 degrees Fahrenheit.

calcination of natural diatomite is done in a rotary kiln at 870-1100 ºC. Diatomaceous earth is used in many industrial applications due to its high porosity, low density porous and permeable structure, chemical resistance, high purity, high specific surface area, absorptive capacity and to its absorbent properties (Ediz et al., 2010).

Flux-Calcined Diatomaceous Earth · Dicalite Management Group

Flux-calcined 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.

Method of preparing diatomite for rapid calcination

Where the diatomite is calcined in a rotary kiln in the form of powder, the occurrence of "hot spots" is common. In a rotary kiln the powdered diatomite simply slides down the side of the rotating kiln, so much of the powder at the surface of the mass of diatomite becomes overheated, causing sintering or melting and glass formation.
