    1 VERMICULITE THE MINERAL Vermiculite is a naturally occurring sheet silicate mineral, usually formed by the hydrothermal alteration of mica minerals such as biotite and phlogopite (Harben and Bates 1990, Brindley and Brown 1980) It ranges in size from microscopic particles of clay mineral to lustrous brown sheets up to half a metre in diameter (MacEwan 1948) although they are usually in theCONCENTRATION OP DIOCTAHEDRAL MICA AND VERMICULITE 95 quartz remained in the sample but probably could be removed by shaking with the "F solution'' for a longer period of time A portion of the 10 Ä mineral, after treatment, is really NH 4 saturated dioctahedral vermiculite (or highcharge montmorillonite), derived by NH 4 saturation and collapse of the expansible layer silicate to 10 A ACONCENTRATION OF DIOCTAHEDRAL MICA AND VERMICULITEThe basic problem with vermiculite asbestos (tremolite and actinolite) is that it is different than the types of asbestos that has been regulated since the 1970s Existing regulations pertain to three other types of asbestos that, if present in a concentration of >1%, are regulated as an asbestoscontaining materialAsbestos Vermiculite TriTech testing

    · Chloritic minerals in the coarse fractions were the most affected by physical breakdown, while micas were generally preserved As a consequence, a concentration of mica layers occurred in the coarse clay fraction, while chloritic residues accumulated in the fine clays These residues exhibited the typical XRD pattern of hydroxyinterlayered intergrade minerals, but the interlayeredvermiculite concentration minerals Vermiculite regardless of the initial cs dose the sequential desorption efciency was very low high sodium concentration increased the desorption from all three minerals however the desorption rate with nh4cl was higher for cases with a low sodium concentration a total desorption rate combined with sodium and nh4clvermiculite concentration minerals dorszewladyslawowoplRecommended Citation Saterdal, A, "Vermiculite, Occurence, Character, and Concentration of Mineral from the Pony District, Madison County, Montana" (1945)"Vermiculite, Occurence, Character, and Concentration of
