Celestite, the most common strontium mineral, consists primarily of
strontium sulfate. The second most common strontium mineral,
strontianite, consists primarily of strontium carbonate.
Reportedly, it is very difficult to concentrate strontium minerals
to grades acceptable for producing chemical compounds. The two most
common celestite-to-strontium carbonate conversion processes are
the soda ash process and the calcining proc ess. Strontium metal is
prod uced by the the rmal reduction of stron tium oxide with meta
llic aluminum and the electrolysis of fused strontium chloride and
ammonium or potassium chloride. Of the two strontium production
processes, the soda ash method is a simpler process; however, the
resulting product is of a lower gra de. The calcin ing method or
black a sh method, produc es chemical-gra de strontium carb onate
(SrCO3 ) which is at least 98% strontium carbonate; whereas, the
soda ash method only produces technical-grade strontium carbonate
>95% pure . Although the soda a sh method is a simple r process,
the lower grade product c auses it to be the less preferred method
of recovery. The black ash method is used by CPC.
The direct conversion of celestine (SrSO4 ) to strontium carbonate
as well as its enrichment by hydrometallurgy were investigated.
Hengyang was also conducted to investigate whether acid
concentration affected the quality of strontium sulfate in
celestine concentrates. Based on the results of a laboratory assay,
it was determined that 98.04% SrSO4 was leached optimally under
agitation. The ground sample of celestine concentrate was then
leached by agitation for three hours after the dimensional analysis
had determined the appropriate grinding time. To determine the
optimal approach for the agitated leaching of strontium carbonate,
different approaches were tested. Various factors, including
temperature, return water, solid percentage, and sodium carbonate
to strontium sulfate ratio, were studied. At 90°C, celestine
completely converts into strontium carbonate with a solid
percentage of 20% and a sodium carbonate to strontium sulfate ratio
of 4:5. As part of the investigation into the possibility of
producing strontium oxide, samples of celestine concentrate and
strontium carbonate produced under optimal conditions were heated
at 500 and 1000°C to determine which phase would form the oxidized
phase. An X-ray analysis indicates that the oxidation phase forms
at a temperature of more than 750°C.
