The invention discloses a dump leaching technique of ground organism of secondary copper sulphide ore with high content of arsenic. The technique comprises the following steps: the secondary copper sulphide ore with high content of arsenic is crushed to 10 to 30mm, and acid mine water of mineral-leaching microorganism with thiobacillus ferrooxidans and thiobacillus thiooxidans is used for leaching the secondary copper sulphide ore with high content of arsenic; while most of the arsenic in the ore is still in leaching residue and a small part of the arsenic is in the leachate, faffinated and electrodeposition liquid; but closed cycle in the production has no effect on the extraction and electrodeposition and standard cathode copper product, thus avoiding the hazard of the arsenic to the environment. The technique has short process, little investment, low cost and energy consumption, no pollution and high rate of recovery, can process the copper ore with high content of arsenic which can not be processed by the traditional smelting technique, and also can process the secondary copper sulphide ore with high content of arsenic and similar secondary copper sulphide ore with high content of arsenic so as to expand the utilization range of resources.
