Copper extracting method of complicated copper oxide ores in multiple copper occurrence states

The invention discloses a copper extracting method of complicated copper oxide ores in multiple copper occurrence states. The method comprises the following steps: (1) the complicated copper oxide ores are crushed and grinded as copper ore powder; and the copper ore powder is mixed with water and concentrated sulfuric acid solution for curing to prepare cured materials; (2) the cured materials areheated by microwaves to prepare heated materials; (3) the heated materials are quenched by water to prepare water-quenched pulp; the heating, the stirring and the leaching are performed by 30-120 minafter the pH value adjustment; and finally, leaching liquid is obtained through filtration; and (4) electro-deposited copper is obtained by the leaching liquid through extraction-electrodeposition process. The method effectively uses the microwave heating energy, reduces the energy input, reduces the heating and leaching cost, only adopts sulfuric acid reagents to achieve both economy and environmental protection, and is
