Here we report precipitation of dolomite at low temperature (30 degrees C) mediated by a mixed anaerobic microbial consortium composed of dissimilatory iron-reducing bacteria (DIRB), fermenters, and methanogens. Initial solution geochemistry is controlled by DIRB, but after 90 days shifts to a syste …
اقرأ أكثرDolomite is also used in container glass. A critical property of the glassmaking grade of dolomite is the iron content, since it is considered a serious impurity in the manufacture of colourless glasses. Very low content of Fe2O3 is needed for the manufacture of colourless glass containers and, sometimes, low iron flat glasses.
