Один из возможных способов извлечения и производства оксида магния из шлама рассолоочистки содового производства

Abstract

The flow diagram of deriving of hydrocarbonate of magnesium and besieged СаСО₃ from a swaft of pickleclearing of soda production of the pickle, obtained at single-stage clearing, (NaCl) from admixtures is offered. Is shown, that the dilution of a swaft of pickleclearing by a concentrated solution CaCl₂ at consequent carbonization by gas of lime furnaces, allows to reach a degree of extraction MgO 88 – 89%.
