Treatment of Dried and Mixed Salts of Karaumbet in Magnesium Hydroxide Following Sodium Sulfate and Chloride Production

Abstract

The process of dried and mixed salt of Karaumbet in magnesium hydroxide with preparation of sodium sulfate, chloride and gypsum simultaneously has been studied. At that the following stages of mixed salts processing were conducted: removing water insoluble residue, sulphur free, cooling of sodium sulfate, deposition of magnesium hydroxide by neutralization of purified solution of sodium and magnesium chlorides using sodium hydroxide. As a result, samples of settled gypsum, sodium sulfate with high brand, purified magnesium hydroxide and sodium chloride solution. The present study chemical, X-ray imaging and thermic analysis were used.
