RESEARCH ON THE DESULFURIZATION TECHNOLOGY AND CALCIUM SULFATE PRODUCTION IN THE PROCESS OF EXTRACTING MAGNESIUM HYDROXIDE FROM BRINE
The paper studied the desulfurization technique in the production of magnesium hydroxide using brine as raw material. Based on the analysis of the various factors whose effects were separately analyzed in several single-factor experiments, an orthogonal experiment was then conducted in order to get a proper set of operating parameters, and the results turned out to be ideal. Meanwhile, some experiments had also been carried out on the improvements of the quality of calcium sulphate dehydrate. The result reveals that both the purity and brightness has been improved quite a lot. The technique adopted here not only realizes the full utilization of the mother liquor of magnesium hydroxide, but also provides favorable conditions to the comprehensive utilization of sea water and brine, especially for the extraction of potassium chloride.
