production method

The first method: carbonization method in the strontium sulfide solution (preparation see bismuth sulfide) carbonization by carbon dioxide gas, the cerium carbonate slurry is subjected to desulfurization washing, vacuum filtration, drying at 300 ° C, and pulverization to obtain a cerium carbonate finished product. The reaction formula is as follows: BaS+CO2+H2O→BaCO3↓+H2S↑ double decomposition method The metathesis reaction is carried out by cerium sulfide and ammonium carbonate, followed by washing, filtration, drying, etc., to obtain a finished cerium carbonate. Its reaction formula is as follows: BaS+(N
H4) 2CO3→BaCO3↓+(N
H4) 2S toxic nepheline conversion method reacts toxic heavy stone ore powder with ammonium salt to form soluble cerium salt, and recovers ammonium carbonate at the same time. The soluble cerium salt is added to ammonium carbonate to precipitate refined cerium carbonate, which is filtered and dried to obtain cerium carbonate. Finished product. The obtained mother liquor is recycled for recycling. ...

use
