Problems solved by technology
A large amount of beneficiation wastewater will be produced in the separation of copper and molybdenum. If the beneficiation wastewater is discharged, it will not only cause waste of water resources, but also cause serious pollution to the surrounding environment.
[0003] With the improvement of environmental protection requirements, copper-molybdenum ore beneficiation wastewater generally cannot be discharged outside, and can only be reused in the beneficiation process; however, copper-molybdenum ore beneficiation wastewater contains a variety of ions, if it is directly reused in the beneficiation process, It will deteriorate the flotation atmosphere and reduce the flotation recovery rate of useful minerals. Therefore, an economically feasible copper-molybdenum ore beneficiation wastewater treatment method is urgently needed in the prior art

Embodiment 1
[0026] Such as figure 2 As shown, get six equal amounts of copper-molybdenum ore raw ore and carry out six times of copper-molybdenum ore roughing operation test respectively; Add lime respectively in every part of copper-molybdenum ore raw ore (the consumption of lime is that every ton of copper-molybdenum ore raw ore adds 1000 grams of lime ), and use the grinding liquids in Table 1 below for grinding, and the grinding liquids used in any two copper-molybdenum ore raw ores are all different. For each copper-molybdenum ore, when the copper-molybdenum ore particles with a particle size not greater than 0.074mm accounted for 75% of the total weight of each copper-molybdenum ore, stop grinding, and add D Base xanthate (the dosage of butyl xanthate is to add 150 grams of butyl xanthate per ton of copper-molybdenum ore), butylammonium black medicine (the dosage of butylammonium black medicine is to add 20 grams of butylammonium black per ton of copper-molybdenum ore medicine) an...

The invention discloses a copper-molybdenum ore dressing wastewater treatment method, comprising: clarifying the copper-molybdenum ore dressing wastewater to obtain clarified copper-molybdenum ore dressing wastewater; Mix according to the ratio of 0.1 to 15:100 by weight, and stir for at least 2 minutes to complete the treatment of copper-molybdenum ore beneficiation wastewater. The invention not only can effectively eliminate the influence of various ions in the copper-molybdenum ore dressing wastewater on the copper-molybdenum flotation, but also has simple process, convenient operation and low cost.
Description
technical field [0001] The invention relates to the technical field of copper-molybdenum ore beneficiation, in particular to a method for treating copper-molybdenum ore beneficiation wastewater. Background technique [0002] At present, most of the beneficiation process of copper-molybdenum ore is to carry out mixed separation of copper and molybdenum first, and then separate copper and molybdenum. A large amount of beneficiation wastewater will be produced in the separation of copper and molybdenum. If the beneficiation wastewater is discharged, it will not only cause waste of water resources, but also cause serious pollution to the surrounding environment. [0003] With the improvement of environmental protection requirements, copper-molybdenum ore beneficiation wastewater generally cannot be discharged outside, and can only be reused in the beneficiation process; however, copper-molybdenum ore beneficiation wastewater contains a variety of ions, if it is directly reused i...
