【Specification】

?Strontium?carbonate?(CAS NO.1633-05-2) is?the carbonate salt of strontium that has the appearance of a white or grey powder. It occurs in nature as the mineral strontianite.Being a carbonate, it is a weak base and therefore is reactive with acids. It is otherwise stable and safe to work with. It is practically insoluble in water (1 part in 100,000). The solubility is increased significantly if the water is saturated with carbon dioxide, to 1 part in 1,000 ,also it is soluble in dilute acids.

【Disposal Methods】
SRP: At the time of review, criteria for land treatment or burial (sanitary landfill) disposal practices are subject to significant revision. Prior to implementing land disposal of waste residue (including waste sludge), consult with environmental regulatory agencies for guidance on acceptable disposal practices.

Use and Manufacturing

【Use and Manufacturing】
Methods of Manufacturing

CELESTITE IS BOILED WITH A SOLUTION OF AMMONIUM CARBONATE OR IS FUSED WITH SODIUM CARBONATE.
... Celestite ore is crushed, ground, & stored in bins before it is fed to rotary kilns. As ground ore is being conveyed to the kilns, it is mixed with ground coke. In the kilns, the celestite is reduced to strontium sulfide, which is known as black ash. ... The product ... from the kilns is collected in storage bins. Black ash ... is fine-ground in a ball mill & fed to a leacher circuit ... where it is dissolved in water & the muds are separated by counter current decantation. ... The filered product, a saturated soln containing 12-13% strontium sulfide, is sent to an agitation tank where soda ash is added to cause precipitation of strontium carbonate crystals ... After precipitation is complete, slurry is pumped to vacuum drum filters where nearly complete liq-solids separation is accomplished. The liq is dilute sodium sulfide soln, which is concentrated by evaporation. ... The filter cake is 60% strontium carbonate solid. ... Strontium carbonate also precipitates from strontium sulfide soln with carbon dioxide.
