Gypsum Common Minerals
As a consequence, gypsum typically occurs as layers associated with limestone, dolostone, shale, and rock salt As seawater evaporates, gypsum is the first ‘salt’ to be precipitated, followed by anhydrite, halite, and finally sylvite Usually found with other evaporite and carbonate minerals, such as anhydrite, calcite, dolomite, borax, andIndepth investigations suggest that the difference in the floatability of gypsum and quartz is prominently intensified by flotation reagents at pH = 2–25, and thus leads to good desilicationA novel method for purification of phosphogypsum Request
