Abstract:
     This invention covers a technology for the production of magnesium sulfate, sodium chloride and potassium chloride. The said process is based on brine blending combined with heating, settling and separation of the mixture at high temperature in a closed system. This process is also called by said invention the "three high method", which without any brine blending procedure makes possible extracting from the raw brine magnesium sulfate monohydrate, followed by recovering sodium chloride and potassium chloride respectively. This invention has many outstanding features, such as high recovery of four salts existing in the brine, saving of raw materials and good energy conservation, high profitability, and good environmental protection for the salt industry production.
