    Production method


    (1) Carbonation method: carbon dioxide is passed through barium sulfide solution (see preparation of


    barium sulfide) to carbonize, the obtained barium carbonate slurry is desulfurization washed, vacuum


    filtration, dried at 300℃ and pulverized to obtain barium carbonate products. its


    BaS + CO2 + H2O→ BaCO3↓+ H2S↑


    Metathesis method: barium sulfide and ammonium carbonate proceeds metathesis reaction, and then


    washing, filtering and drying to obtain bismuth products. its


    BaS + (NH4) 2CO3 → BaCO3 ↓ + (NH4) 2S


    Poison nepheline conversion method: witherite ore reacts with ammonium salt to generate soluble barium


    salt, and ammonium carbonate is recycled and re-used, ammonium carbonate is added into soluble


    barium salt to precipitate refined barium carbonate, it is filtered and dried to obtain barium carbonate


    products. The obtained mother liquor is recycled use.



    (2) Carbonization method. Reaction equation:


    BaS + CO2 → BaCO3 ↓ + H2S ↑


    Operational method: 1L barium sulfide aqueous solution of 180g/L reacts with carbon dioxide at 70℃ to


    produce barium carbonate precipitation. Precipitation is mixed with 10ml 25% aqueous ammonia, at 60℃


    desulfurization for 20min. Filtered, and dried to obtain the precipitated barium carbonate, product


    contains 0.46% sulfur.


    Metathesis method. Reaction equation:


    BaCl2 + NH4HCO3 + NH4OH → BaCO3 ↓ + 2NH4Cl + H2O


    Operational method: At 30℃, 23.6L containing ammonium bicarbonate 56.1g /L aqueous solution and


    1.36L ammonia is mixed in 50L kettle and then at 50℃, within 2h dropping 21.6L 200.3g/L barium


    chloride solution, it is stirred for 30min at 40℃. Filtered, dried at 140 ℃, pulverized to obtain barium


    carbonate which average particle diameter d is 0.8μm, purity is 99.8%.


    Witherite method. Reaction equation:


    BaCO3 + 2NH4Cl → BaCl2 + 2NH3 + H2O + CO2


    BaCL2 + (NH4) 2CO3 → BaCO3 ↓ + 2NH4Cl


    Operational method: 100 g 80% of toxic heavy powder (120 mesh) and 60g ammonium chloride is well


    mixed, it is rapidly put into 650℃ muffle furnace and reacts for 3min. After cooling, it is flooded, filtered,


    removed debris to obtain barium chloride solution, 36g ammonium carbonate is added, precipitating


    barium carbonate, it is filtered, dried and pulverized, the conversion rate is 91%.
