Barite | Micronised Minerals

Barite is used by the petroleum industry as a weighting material in formulation of “drilling mud” Barite increases the hydrostatic pressure of the drilling mud allowing it to compensate for highpressure zones experienced during drilling The softness of the mineral also prevents it from damaging the drilling tools during the drilling process and enables it to serve as a lubricantSome geological evidence indicates that the original material of most gypsum beds was anhydrite This view is apparently supported where gypsum beds are observed to grade into anhydrite at depth, and by textural relationships which indicate that gypsum is formed later than anhydrite; in both cases, however, the anhydrite itself may have resulted from the dehydration of gypsum Later opinionsALEX STREKEISENGypsum

Barite (BaSO4) and celestite (SrSO4) are the endmembers of a nearly ideal solid solution Most of the exploitable deposits of celestite occur associated with evaporitic sediments which consist of gypsum (CaSO4·2H2O) or anhydrite (CaSO4) Barite, despite having a broader geological distribution is rarely present in these deposits In this work, we present an experimental study of the13/02/2017· I agree this is gypsum, not barite The Norman, Oklahoma barite clusters have much fatter 'petals' compared to their diameter than a typical gypsum 'desert rose' specimen It would not be correct to call this specimen selenite (a term used much too broadly), because selenite refers to the colorless, transparent, easily cleavable gypsum variety, and not any ol' generic gypsum specimen 14th FebIdentity Help : Desert Rose Barite or Gypsum?

Gypsum Chemical Formula, Properties, Types, Uses and FAQ

Gypsum rock is first mined or quarried, then crushed and ground to a fine powder It then goes through a process called calcining where heat at 350 degrees is supplied to the gypsum powder which removes 3/4 th of the water molecules Hemihydrate is the name of calcined gypsum which is then used in gypsum board, gypsum plaster, and otherSome geological evidence indicates that the original material of most gypsum beds was anhydrite This view is apparently supported where gypsum beds are observed to grade into anhydrite at depth, and by textural relationships which indicate that gypsum is formed later than anhydrite; in both cases, however, the anhydrite itself may have resulted from the dehydration of gypsum Later opinionsALEX STREKEISENGypsum
