采用带有微滤陶瓷膜气体分布器的转鼓反应器，采用氧化亚铁硫杆菌对毒砂进行生物浸出。通过调节曝气量和转鼓转速可以改善气体传质性能，并且可以在高矿浆密度下保持菌株的高生物活性。毒砂生物浸出表明转鼓反应器可以允许较高的矿浆密度，这有利于反应器用于硫化物矿物的生物浸出。
A rotating-drum reactor with a gas-sparger of microfiltration ceramic membrane was used for arsenopyrite bioleaching by Acidithiobacillus ferrooxidans. The gas mass transport performance could be improved by adjusting the aeration rate and drum rotation speed, and high bioactivity of bacterial strains could be maintained at high pulp densities. Arsenopyrite bioleaching showed that higher pulp density could be allowed in the rotating-drum reactor, which was favorable to the reactor used in the bioleaching of sulfide minerals.
