What methods of strontium carbonate production

the following by the appropriate xin chemical industry to introduce the strontium carbonate production methods.

( 1) Double decomposition method of strontium carbonate production are mostly by double decomposition method. Double decomposition method with lapis lazuli ( Strontium sulfate) Reaction to generate sodium sulfate powder and sodium carbonate solution ( In solution) And strontium carbonate precipitation, raw strontium carbonate containing a small amount of strontium sulfate, the refined refinement. Main reaction is as follows:

SrSO4 + Na2C03 & rarr; SrC03↓ ＋Na2SO4

SrC03＋2HN03→ Sr( 3号) 2＋H20＋CO2↑

Sr( 3号) 2＋Na2C03→ SrC03＋2NaNO3

( 2) Add coke to restore satin reduction method in lapis lazuli to burn, strontium sulfide. Generation of strontium sulfide dissolves, partially hydrolyzed into hydrogen strontium oxide and sulfur hydrogenated strontium. The solution with sodium carbonate liquid, or with CO2 carbide, quick strontium carbonate. Using carbon reduction method factories are mostly low strontium yield, ore utilization is unreasonable and the 'three wastes' pollution and other issues.

( 3) Method of comprehensive utilization from the mother liquor of strontium chloride extraction strontium chloride, reacts with sodium carbonate solution.
