Example Embodiment
[0016] Example 1:
[0017] The embodiment of the present invention proposes a leaching method for recovering copper from malachite-type copper oxide ore. The method includes: crushing and grinding the copper oxide ore, wherein the weight percentage of the ore with a particle size of 38 μm is 75%; the concentration of trichloroacetic acid is 0.25 mol / L; the mass liquid-solid ratio of the leaching agent and the ore is 20 :1; Heat the leaching system at a constant temperature to 30°C and keep it constant, and fully stir for 30min; the reaction will obtain a copper-containing solution suitable for the next step of extraction and electrowinning. The leaching rate of the copper is about 96.8%.

[0018] Example 2:
[0019] The embodiment of the present invention proposes a leaching method for recovering copper from malachite-type copper oxide ore. The method includes: crushing and grinding the copper oxide ore, the weight percentage of the ore with a particle size of 38 μm is 80%; the concentration of trichloroacetic acid is 0.5 mol / L; the liquid-solid ratio of the leaching agent and the ore mass is 15 :1; Heat the leaching system at a constant temperature to 35°C and keep it constant, and fully stir for 30min; the reaction obtains a copper-containing solution suitable for the next extraction and electrowinning. The leaching rate of the copper is about 97.5%.
