Abstract

PURPOSE: To easily manufacture high magnesia dolomite in a high yield with a reduced MgO loss by treating a mixed slurry of calcite-contg. low MgO dolomite and water, with HCl, adjusted to a specified temp.
CONSTITUTION: Water is mixed into calcite-contg. low MgO dolomite adjusted to 1mm or less in grain size and 5W20°C to prepare a slurry of 2W50% dolomite concn. To this slurry is added 1W12N HCl in an amt. of 1 eq. or more to the calcite content, and then the slurry is adjusted to 5W20°C and treated with HCl. By this method elution of MgO is inhibited, and powered high MgO dolomite contg. MgO≥18% is obtd. in a high yield.
