Embodiment 1
[0026] This embodiment includes the following steps:
[0027] Step 1: Crushing the combined copper oxide ore and then grinding to a particle size of 0.074 mm to 0.15 mm to obtain ore powder; the mass content of copper in the combined copper oxide ore is 1.08%, and the combined copper oxide ore in the combined copper oxide ore is The phase occupancy rate is 44.76%;
[0028] Step 2. Mix the lye and the ore powder described in step 1 uniformly at a mass ratio of 1.036:1, and stir for 60 minutes at a temperature of 90° C. for pretreatment, and obtain pretreatment liquid and pretreatment slag after filtering; The lye is a sodium hydroxide solution with a mass concentration of 3.47%;
[0029] Step 3, mix the water and the pretreated slag described in step 2 uniformly at a mass ratio of 2:1 to obtain a solid-liquid mixture, then add concentrated sulfuric acid to the solid-liquid mixture, and mix the solid-liquid mixture under stirring conditions Carry out acid leaching treatment, o...
