Study on Application of Acidithiobacillus thiooxidans in Dephosphorization of Hematite in Enshi
氧化硫硫杆菌对难选恩施赤铁矿脱磷的影响

Dephosphorization of phosphorus-containing 0.90% high-phosphorus hematite ore in Enshi with the strain of Acidithiobacillus thiooxidans(At.t) was studied.The preliminary results showed that the maximum dephosphorization rate could reach up to 71%,which meant that Acidithiobacillus thiooxidans had a better dephosphorization effect.10% of the strain concentration,75 mm of hematite particles,4.0 of initial culture pH value were obtained as the optimized leaching conditions by studying the growth characteristic...
