Summary: | The invention relates to mineral leaching bacteria and a biological high-temperature heap leaching technique of native copper sulfide ore that uses the leaching bacteria. The leaching bacteria are preserved in China Center for Type Culture Collection in Wuhan University, and the preservation numbers are respectively CCTCC NO of M207062, M207063, M207064 and M206029. The heap leaching technique roughly smashes the native copper sulfide ore, finely smashes the native copper sulfide ore, and preprocesses the native copper sulfide ore by spraying a bacteria-containing solution, thus obtaining ore particles that are suitable for biological leaching. The ore particles are processed by working procedures of stacking, heap leaching and spraying, leaching liquid recycling, copper-rich liquid extracting, back extracting and electrodeposition and the like, thus obtaining marketable cathode copper. The heap leaching process adopts a method that includes room temperature bacteria, medium thermophiles and extreme thermophi |
