INTRODUCTION. Diatomite rock is a loose, earthy or loosely cemented porous and lightweight rock of sedimentary origin, mainly formed by fragments of armor (skeletons) of diatom algae: diatomea and radiolaria. Diatomite is a microscopic diatom alga whose size ranges from 0.75 to 1500 m; sometimes this rock is called infusorial earth, kieselguhr ...

 · Laboratory experiments were performed on a Brazilian diatomite from Bahia State to produce an industrial product for use as a filter aid. Bench and pilot-plant tests were conducted. The tests consisted of diatomite desegregation, organic matter and clay removal, filtration, drying and calcination.

Diatomite can be considered as inert due to the chemical composition, which imply that diatomite does not affect taste, smell or colour. Filtration is one of the most widely used …

Chemical tests on the clayey diatomite showed that it was an acid rock with approximately 60% SiO 2.The parameters of the amount of SiO 2 and Al 2 O 3 present, as well as the mass loss (LOI), obviously indicate the determined mineral phases—opal, illite, quartz, feldspar, chlorite in the treated sample. The total alkaline oxide content of 2.53% …

 · Diatomite is abundant in many areas of the world and has unique physical characteristics, such as high permeability (0.1-10 mD) and porosity (35-65%) (Murer and Mobil, 2000), small particle size, low thermal conductivity and density (Hassan et al., 1999) and high surface area (Gaoet al., 2005). The properties of diatomite's surface, such s a

 · Furthermore, the technique has the key benefit of reducing the feed to the grinding and flotation circuits, which results in a reduction in the required size of these circuits, and therefore reduced capital cost and energy demand.

 · Diatomaceous earth is a greatly exploited mineral, reaching a world mine production of 2,120,000 metric tons in 2012 [ 4 ]. It has been widely used as filter, adsorbent, remover of contaminants, mineral filler, abrasive, and catalytic support [ 5 – 9 ].

Diatomite is a non-metallic mineral with a vesicular structure, strong adsorption capabilities, and a large specific surface area. Because of its low cost and wide availability, it is sometimes used as papermaking filler (Li et al. 2008).

Calcination temperature and sodium carbonate addition influenced diatomite particle size distribution. Optimum filtration rates for calcined products were obtained at 900°C and 47 …

The diatomite has these applications due to its lightweight, porosity, and ability to endure higher temperatures: For polishing metals, it's used as an abrasive. Toothpaste and toothpowder manufacturers use it. Steam pipelines and blast furnaces are insulated. Filters are used in the brewing, oil refining, sugar, and antibiotic industries.

 · But the impact strength reduced sharply when the addition of diatomite was more than 1 phr. The reason of the phenomenon is that the diatomite plays the role of defects in PVC and it works against the absorption of impact strength energy. It was proved by the results of scanning electron microscopy. J. VINYL ADDIT.

Diatomite (diatomaceous earth, kiselguhr) is a sedimentary rock of marine or lacustrine deposition.
