Abstract

Room temperature milling of celestine mineral and dry sodium hydroxide powder mixture was conducted in a planetary ball mill. Strontium sulfate, which is a main component in the celestine sample reacts spontaneously with sodium hydroxide powder during milling, forming strontium hydroxide. As a result of carbonation in a final product of milling, strontium hydroxide is transformed into strontium carbonate. The milling operation enables to accelerate the reaction rate. The strontium carbonate in the product can be concentrated up to over 90% by washing sodium sulfate out with water.
