Abstract
Abstract Strontium sulphide (SrS) was water-leached at 85°C, generating a saturated solution of approximately 50 g/L Sr. About 92% of the strontium contained in the SrS was leached within 60–80 min. Almost all of the water-soluble strontium were completely leached out from the sulphide material. The strontium-saturated solution was treated with carbon dioxide to precipitate strontium carbonate (SrCO 3 ). Precipitation efficiencies in excess of 99% were attained in both batch and continuous multi-column test programs. Hydrogen sulphide gas was generated as a byproduct in the precipitation process at a slurry pH≤8. Particle size analyses of SrCO 3 precipitates indicate that a longer retention time enhances crystal growth.
