gypsum bentonite vermiculite

vermiculite deposits. World production of vermiculite in 2004 was 520 000 tonnes (Table 42) (Potter 2005). World production is dominated by South Africa and the USA (about 70% of production) (Table 42). Other countries with significant known deposits include Erigel MPSA is a natural Sodium Bentonite, which mineral content as dioctahedral montmorillonite is higher than 70%.It has more than 90% of power adsorption aflatoxin B1 (AFB1). This natural Sodium Bentonite acts as feed additive, as well as reducing aflatoxin AFB1 and Zearalerona (ZEA).

Vermiculite vs. Perlite: Similarities, Differences, and

Vermiculite is made of compressed silicate material derived from mined rocks that looks like dry flakes. Vermiculite is heated to a high temperature of 1600 . The resulting flakes are absorptive and spongy with a golden brown to dark brown color. Some varieties are

Vermiculite is a hydrous phyllosilicate mineral which undergoes significant expansion when heated. Exfoliation occurs when the mineral is heated sufficiently, and commercial furnaces can routinely produce this effect. Vermiculite forms by the weathering or hydrothermal alteration of biotite or phlogopite.

Gypsum also occurs in large quantities as the industry by-product, otherwise known as flue-gas desulphurized (FGD) gypsum. There are not significant differences in the composition of finished drywall products made using these different source materials, but natural gypsum is preferred over FGD gypsum because the FGD drywall production process can release mercury into the environment.

Bentonite is not classified as dangerous for supply under EEC regulations. Bentonite does not require labelling for safety information or risk information. Bentonite is 5mg/m respiritable dust in a TWA 8 hour's reference period. Refer to all applicable local
