本文阐述了越来越多的兴趣，这是表现在微生物，氧化亚铁硫杆菌，参与生物湿法冶金提取过程。目前研究的各种问题是非常重要的，以便更好地了解控制微生物生长的因素，并因此，金属溶解现象。在几个矿址，微生物浸出技术目前正在工业规模上实施，特别是用于从低品位材料中回收铜和铀。然而，一个更进一步的潜在可能性的应用微生物浸出金属硫化物的准确评估需要一个更基本的知识的物理和化学因素的相互作用与T的增长。ferrooxidansin纯的和混合的文化，包括异养和嗜热共生。总之，这些微生物浸出技术的未来工业开发在世界许多国家都是非常有吸引力的。
The present article illustrates the increased interest which is manifested in the microorganisms,Thiobacillus ferrooxidans, involved in the biohydrometallurgical extraction processes. The wide varieties of problems currently studied are very important in order to gain a better understanding about the factors which are governing the growth of microorganisms, and as a consequence, the metal dissolution phenomena. In several mining sites, the microbiological leaching techniques are currently practiced at industrial-scale, especially for recovery of copper and uranium from low-grade materials. However, an accurate assessment of further potential possibilities for the application of microorganisms in leaching metal sulfides requires a more fundamental knowledge about the interactions of the physical and chemical factors with the growth ofT. ferrooxidansin pure and mixed cultures including heterotrophic and thermophilic cohabitants. Altogether, the future industrial exploitation of these microbiological leaching techniques are very attractive in many countries of the world.
