Paper Title:
Recovery of Magnesium Oxide and Magnesium Hydroxide from the Waste Bittren
  Abstract

The recycling of magnesium chloride brines via a multi-step chemical reaction and precipitation process has been studied in waste bittern from a salt purification plant. In this study, the rates of particle (magnesium hydroxide) growth, the effects of initial concentration of reactants and optimum condition of reaction to make high purity magnesium hydroxide were investigated. Produced magnesium hydroxide was separated and washed using carboxy methyl cellulose as sedimentation agent, and used sodium stearate to prevent particle from aggregating. The mean particle size of obtained high quality magnesium hydroxide are 5 μm and concentration is 99.5%.
