摘要
Abstract
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 .关键词
