嗜酸氧化亚铁硫杆菌的高效培养及浸出黄铜矿初探
Efficient culture of Acidithiobacillus ferrooxidans and preliminary study on chalcopyrite bioleaching
摘要
Abstract
By feeding of ferrous sulfate into sulfide m ineralsm edium to maintain the Fe 2+ With in the concentration range from 4 g/L to 8 g/L , the biom ass of A cidith iobacillus ferroox idans could reach 6 .25 ×l08 cells/m L with in 39 hours . At the same time the conversion rate and production in tensity was improved without reducing the special growth rate . The prelim inary study on low-grade chalcopyrite bioleaching at low redox potentials was carried out . The results showed that the leaching rate of copper could reach 28 .5 percent with in 30 days, and the Fe2+ . rather than sulfide minerals , w as utilized as the bacteria growth energy in that leaching period .关键词
