Production of mg(oh)

Claim 1

THE METHOD OF PRODUCING MG(OH)2 CAKE HAVING A LOW WATER CONTENT, HIGH MG(OH)2 CONTENT, AND ANALYZING LESS THAN 1.5 PERCENT CAO BASED ON THE MGO BY ANALYSIS, WHICH COMPRISES CALCINING DOLOMITE TO PRODUCE DOLIME, SLAKING THE DOLIME WITH WATER IN AN AMOUNT SUFFICIENT TO PROVIDE AN EXCESS THEREOF OVER THAT REQUIRED TO CONVERT THE CAO THEREIN CA(OH)2 IN AN AQUEOUS SLURRY AND TO PROVIDE AN ALKALINE NORMALITY OF BETWEEN 6 AND 27, MAINTAINING THE SLAKING TEMPERATURE AT BETWEEN 30* AND 95* C., ADMIXING THE AQUEOUS SLURRY THUS PRODUCED WITHIN A PERIOD OF TWO HOURS AFTER THE BEGINNING OF THE SLAKING OPERATION WITH CACL2 IN SUCH AMOUNT AS TO PRODUCE A CACL2-TREATED SLURRY OF WHICH THE MOTHER LIQUOR HAS A SPECIFIC GRAVITY OF BETWEEN 1.10 AND 1.15, ADMIXING THE CACL2-TREATED SLURRY AT BETWEEN 20* AND 70*C. WITH A MAGNESIUM HALIDE-CONTAINING BRINE IN AN AMOUNT SUFFICIENT TO YIELD AT LEAST SLIGHTLY MORE THAN THE STOICHIOMETRIC QUANTITY OF CA(OH)2 NECESSARY TO REACT WITH THE MAGNESIUM HALIDE IN THE BRINE TO PRODUCE MG(OH)2 SUSPENDED IN THE SPENT BRINE AQUEOUS SUSPENDING MEDIUM AND THEREAFTER RECOVERING THE MG(OH)2, AND WASHING THE MG(OH)2 THUS RECOVERED WITH WATER.

Claim 2

THE METHOD OF PRODUCING MG(OH)2 CAKE HAVING A LOW WATER CONTENT, HIGH MG(OH)2 CONTENT, AND ANALYZING LESS THAN 1.5 PERCENT CAO BASED ON THE MGO BY ANALYSIS, WHICH COMPRISES CALCINING DOLOMITE TO PRODUCE DOLIME, SLAKING THE DOLIME WITH WATER IN AN AMOUNT SUFFICIENT TO PROVIDE AN EXCESS THEREOF OVER THAT REQUIRED TO CONVERT THE CAO THEREIN CA(OH)2 IN AN AQUEOUS SLURRY AND TO PROVIDE AN ALKALINE NORMALITY OF BETWEEN 6 AND 27, MAINTAINING THE SLAKING TEMPERATURE AT BETWEEN 30* AND 95* C., ADMIXING THE AQUEOUS SLURRY THUS PRODUCED WITHIN A PERIOD OF TWO HOURS AFTER THE BEGINNING OF THE SLAKING OPERATION WITH CACL2 IN SUCH AMOUNT AS TO PRODUCE A CACL2-TREATED SLURRY OF WHICH THE MOTHER LIQUOR HAS A SPECIFIC GRAVITY OF BETWEEN 1.10 AND 1.15, ADMIXING THE CACL2-TREATED SLURRY AT BETWEEN 20* AND 70*C. WITH A MAGNESIUM HALIDE-CONTAINING BRINE IN AN AMOUNT SUFFICIENT TO YIELD AT LEAST SLIGHTLY MORE THAN THE STOICHIOMETRIC QUANTITY OF CA(OH)2 NECESSARY TO REACT WITH THE MAGNESIUM HALIDE IN THE BRINE TO PRODUCE MG(OH)2 SUSPENDED IN THE SPENT BRINE AQUEOUS SUSPENDING MEDIUM AND THEREAFTER RECOVERING THE MG(OH)2, AND WASHING THE MG(OH)2 THUS RECOVERED WITH WATER.
