对氧化亚铁硫杆菌浸出深海多金属结核中有价金属的可行性进行了实验，着重研究 了矿浆浓度、接种量、温度、浸出过程中ｐＨ值对结核中有价金属钴和镍浸出率的影响，同时对 氧化亚铁硫杆菌进行了驯化．实验表明：采用Ｌｅａｔｈｅｎ培养基，加入适量黄铁矿作为菌种的营养 基质和浸出过程中的还原剂，多金属结核，在常温、酸性环境下，可直接浸出金属铜、钻、镍、锰 和铁． The feasibility of leaching Thiobacillus ferrooxidans with valuable metals from deep-sea polymetallic nodules was studied. The effects of pulp concentration, inoculum size, temperature, leaching process on the leaching rates of cobalt and nickel in nodules Influence, at the same time, the domesticated Thiobacillus ferrooxidans. Experiments show that: the use of Leathen medium, adding an appropriate amount of pyrite as a nutrient substrate and the leaching process of reducing agent, polymetallic nodules, at room temperature, acidic environment, the direct leaching of copper, diamond, nickel, manganese and iron.
