Embodiment 1
[0057] The comprehensive copper grade of the low-grade copper sulfide ore raw ore used in this embodiment is 0.14%, and it is pre-selected and discarded, and the steps are as follows:
[0058] 1. The raw ore of low-grade copper sulfide ore is crushed with a jaw crusher, and then the crushed product is dry-screened with a sieve with an aperture of 60mm, and the product on the sieve with a particle size of +60mm is returned to the crusher for crushing until all the ore passes through A sieve with a hole diameter of 60mm can obtain -60mm particle size ore.
[0059] 2. Dry-screen the -60mm ore with a sieve with a hole diameter of 10mm to obtain -10mm ore and -60+10mm ore.
[0060] 3. The -10mm grain size ore is sequentially wet-screened with screens with apertures of 6mm, 2mm, and 0.15mm to obtain -10+6mm grain size ore, -6+2mm grain size ore, -2+0.15mm grain size ore Ore and -0.15mm grain grade ore, of which -0.15mm grain grade ore is primary mud (copper grade see Table 1), dire...
Embodiment 2
[0069] The comprehensive copper grade of the low-grade copper sulfide ore raw ore used in this embodiment is 0.13%, and it is subjected to joint pre-selection and discarded, and the steps are as follows:
[0070] 1. The raw ore is crushed with a jaw crusher, and then the crushed product is dry screened with a sieve with an aperture of 60mm, and the product on the sieve with a particle size of +60mm is returned to the crusher for crushing until all the ore passes through the sieve with an aperture of 60mm net to get -60mm grain grade ore.
[0071] 2. Dry-screen the -60mm ore with a sieve with a hole diameter of 10mm to obtain -10mm ore and -60+10mm ore.
[0072] 3. Wet-screen the ore with a particle size of -10mm in turn using sieves with apertures of 6mm, 2mm, and 0.15mm to obtain ore with a particle size of -10+6mm, ore with a particle size of -6+2mm, and ore with a particle size of -2+0.15mm Ore and -0.15mm grain grade ore, of which -0.15mm grain grade ore is primary mud (c...
Embodiment 3
[0081] The comprehensive copper grade of the low-grade copper sulfide ore raw ore used in this embodiment is 0.13%, and it is subjected to joint pre-selection and discarded, and the steps are as follows:
[0082] 1. The raw ore is crushed with a jaw crusher, and then the crushed product is dry screened with a sieve with an aperture of 60mm, and the product on the sieve with a particle size of +60mm is returned to the crusher for crushing until all the ore passes through the sieve with an aperture of 60mm net to get -60mm grain grade ore.
[0083] 2. Dry screen the -60mm size ore with a 10mm sieve to obtain -10mm size ore and -60+10mm size ore, and then use the -60+10mm size ore to use a 32mm sieve Perform dry sieving to obtain -60+32mm ore and -32+10mm ore.
[0084] 3. Wet screen the -10mm grain grade ore in turn with sieves with apertures of 6mm, 2mm and 0.15mm to obtain -10+6mm grain grade ore, -6+2mm grain grade ore, -2+0.15mm grain grade ore Grade ore and -0.15mm grain g...
