specific Embodiment approach 1
[0026]A method for efficiently recovering copper and molybdenum associated with gold rhenium from porphyry copper-molybdenum ore, comprising the following steps:
[0027] Step 1. Crush the raw ore and grind it finely with a ball mill. The content of the grinding fineness of -0.074mm particle size grade accounts for 55% of the total weight of the ore. During the grinding process, add 500g / t of lime, add water to adjust the slurry until the pH of the ore is 7. Obtain the ore grinding slurry for use;
[0028] Step 2. Add 100g / t of water glass, 80g / t of butyl xanthate, 10g / t of sulfonated kerosene, and 20g / t of methyl isobutyl carbinol to the grinding pulp obtained in step 1 in order to carry out copper-molybdenum mixing. Flotation roughing, copper molybdenum mixed flotation roughing time 3 ~ 6min, get copper molybdenum mixed flotation rougher concentrate and copper molybdenum mixed flotation rougher tailings, stand-by;
[0029] Step 3, grind the copper-molybdenum mixed flotation...

[0047] A method for efficiently recovering copper and molybdenum associated with gold rhenium from porphyry copper-molybdenum ore, comprising the following steps:
[0048] Step 1. Crush the raw ore and grind it finely with a ball mill. The content of the grinding fineness -0.074mm particle size grade accounts for 60% of the total weight of the ore. During the grinding process, add 800g / t of lime, add water to adjust the slurry until the pH of the slurry is 8. Obtain the ore grinding slurry for use;
[0049] Step 2. Add 200g / t of water glass, 100g / t of butyl xanthate, 15g / t of sulfonated kerosene, and 30g / t of methyl isobutyl carbinol to the grinding slurry obtained in step 1 in order to carry out copper-molybdenum mixing. Flotation roughing, copper molybdenum mixed flotation roughing time 3 ~ 6min, get copper molybdenum mixed flotation rougher concentrate and copper molybdenum mixed flotation rougher tailings, stand-by;
[0050] Step 3. Grind the copper-molybdenum mixed flota...
specific Embodiment approach 3
[0069] A method for efficiently recovering copper and molybdenum associated with gold rhenium from porphyry copper-molybdenum ore, comprising the following steps:
[0070] Step 1. Crush the raw ore and grind it finely with a ball mill. The content of the grinding fineness -0.074mm particle size grade accounts for 55-60% of the total weight of the ore. During the grinding process, add lime 500-800g / t, add water to adjust the slurry Until the pH of the pulp is 7-8, the grinding pulp is obtained and set aside;
[0071] Step 2. Add water glass 100-200g / t, butyl xanthate 80-100g / t, sulfonated kerosene 10-15g / t, methyl isobutyl carbinol 20- 30g / t, carry out copper-molybdenum mixed flotation roughing, copper-molybdenum mixed flotation roughing time 3 ~ 6min, get copper-molybdenum mixed flotation roughing concentrate and copper-molybdenum mixed flotation roughing tailings, stand-by;
[0072] Step 3, using a ball mill to grind the copper-molybdenum mixed flotation rougher concentrate ...
