Method of strontium carbonate preparation

A technique for humidity decrease of strontium carbonate, obtained by its precipitation by sodium carbonate out of strontium salt solution with further precipitate separation, its washing by repulpation and drying, is proposed. The use of sodium carbonate solution with 0.8-1.5 g/l concentration during the precipitation repulpation permits to decrease the product humidity from 45-50% to 29-35%, to improve its quality, to reduce energy consumption for filtration and drying of precipitation
