In thermophilic anaerobic bacterial cultures phosphogypsum is microbiologically transformed to H2S, SO4(2-), Ca(2+), phosphate and calcium carbonate.The maximal received process efficiency amount to approximately 97%.The postcultivation sediments contan similar amounts of calcium, more phosphorus, more ferrum and magnesum, and smalle amounts of sulfur (mg/g of deposit) than phosphogypsum.The sediments may be applied as an agricultural fertilizer or a source of rare earths ores.
