在自然界极端环境中采集到一种能在5～100℃环境中生长的球状原生质生物体，并成功地对其进行培养。生物体命名为超高温古细菌。这种古细菌的繁殖能力极强，浸矿过程中可以自动升温，温度达50～100℃。介绍了结合氧化铜矿工业生产状况和氧化‐硫化混合铜矿工业试验结果。对不同性质物料的工业试验结果表明：无论是原生硫化铜矿、结合氧化铜矿，还是缺硫、低硫并含不同品位铁的物料，用超高温古细菌浸出，金属浸出率均较高，而且自动高温（50～70℃）或超高温（70～100℃）；酸耗大幅度降低；对于低硫氧化铜矿，有效浸出时间通常在4～8 h 之内，低液固体积质量比、缺氧或缺少空气等不良因素对高温和铜的浸出影响不明显，而低压条件对高温产生影响显著。

A kind of spherical protoplast which can grow in the environment of 5 - 100 ℃ is collected in extreme natural environment ,and it has been successfully domesticated and cultivated .The protoplast is named as hyper thermophile archae .The hyper thermophile archae has extremely reproductive ability ,and it also can automatically increase temperature to 50 - 100 ℃ in the leaching process of copper ore .The industrial production of a bound‐type copper oxide ore ,and industrial tests of a mixed ore of copper sulfide and copper oxide ore are detail introduced .The test results of different property materials show that whether primary copper sulphide ore or bound‐type copper oxide ore ,and the ore shortage of or low grade of sulfur with low or high grade iron ,the leaching rate of copper ,and automatic high or hyper high temperature without external heating ,and saving sulfuric acid are significant improved .The effects of low liquid‐solid ratio ,low air temperature ,hypoxia and other factors on the leaching of low grade copper sulphide‐oxide ore are no obvious .The lower atmosphere pressure has obvious effect on maxium temperature coming‐being in the area of high altitude ,and the leaching time is usually between 4 - 8 hours .
