本文探讨了氧化铁硫杆菌的生长条件和细菌吸附在浸出黄铜矿中的作用.在比较试验中采用了生长于硫、硫代硫酸盐和亚铁离子基质的氧比钱硫杆菌.培养于硫这一固体基质的细菌,需要一种细菌吸附力,该力与无机盐介质中有可溶性硫代硫酸盐和亚铁离子存在时所需的那种力不同.培养于固体基质的细胞呈现出比那些培养于液体基质的细胞更高的浸出率.研究发现利用固体基质培养的细胞在浸出时,不会出现液体基质培养的细胞在浸出过程中初期的粘滞阶段.
This article explored the growth conditions of Thiobacillus ferrooxidans and the role of bacteria in leaching chalcopyrite. In comparison experiments oxygen was used to grow in sulfur, thiosulfate and ferrous ion matrices than Thiobacillus thiurnis. Bacteria cultured on a solid substrate of sulfur require a bacterial adsorption force that is different from that required in inorganic salt media in the presence of soluble thiosulfate and ferrous ions. Cells cultured on solid matrices showed higher leaching rates than those cultured on liquid matrices. The study found that cells cultured on a solid substrate did not show an initial phase of viscosity during the leaching process when leached.
