Fig. 1 shows the flow chart of the processing method of the waste water producing in the copper-molybdenum ore ore dressing process that the embodiment of the present invention one provides.
Detailed description of the invention
Also by reference to the accompanying drawings the present invention is described in further detail below by specific embodiment.
Embodiment mono-
Please refer to Fig. 1, the embodiment of the present invention provides the processing method of the waste water producing in a kind of copper-molybdenum ore ore dressing process, comprises the following steps:
Step 101: the first wastewater collection producing after the mine tailing obtaining in bulk flotation process is concentrated, and turn back in the process of bulk flotation;
Step 102: the second wastewater collection producing after the molybdenum concntrate obtaining in refining process is concentrated, and turn back to and separate in the process of roughly selecting;
Step 103: the 3rd wastewater collection producing after the copper concentrate obtaining in the process of scanning is concentrated, and turn back in the process of scanning.
The processing method of the waste water producing in this copper-molybdenum ore ore dressing process that the embodiment of the present invention provides, after the mine tailing obtaining is concentrated, produces the first waste water in bulk flotation process, will after the first wastewater collection, turn back in the process of bulk flotation; Equally, concentrated the molybdenum concntrate obtaining in refining process rear the second waste water producing is turned back to and separated in the process of roughly selecting; The 3rd waste water producing after the copper concentrate obtaining in the process of scanning is concentrated turns back in the process of scanning.In the operation of ore dressing, in the process that bulk flotation, separation are roughly selected and scanned, need additionally to add water, but the water consumption in whole operation process has also been saved in this recycling that various waste water segmentations is back to the method for parent job flow process separately and has realized various waste water of the present invention simultaneously.Therefore, in itself and prior art, need to additionally set up sewage treatment plant or use the operation of chemical agent degraded to compare, it has saved the cost of wastewater treatment greatly.
In addition, in ore-dressing practice, owing to all containing a certain amount of medicament (collecting agent or inhibitor) in various waste water, therefore, after in the work flow that is back to different phase, the medicament in waste water has also obtained utilization again, therefore, also reduce the use amount of operation process Chinese medicine, further saved the cost in ore-dressing practice.
For the method that makes the embodiment of the present invention one is better applied, more effectively be applied in ore-dressing technique, the present invention also provides embodiment bis-on the basis of above-described embodiment one, embodiment bis-is further restriction and the increases to making on the basis of embodiment mono-, is now described in detail and explains:
Embodiment bis-
The step of embodiment mono-is carried out concrete refinement and detailed description by the present embodiment, specifically comprises the following steps:
1, after the first Waste Water Centralized producing after the mine tailing obtaining in bulk flotation process is concentrated and shine 0.5-1 hour at 10-30 DEG C, then turn back in the process of bulk flotation.
2, the second waste water producing after the molybdenum concntrate obtaining in refining process is concentrated also shines 0.5-1 hour at 10-30 DEG C, and turns back to and separate in the process of roughly selecting.
3, by concentrated the copper concentrate obtaining in the process of scanning rear the 3rd waste water producing and at 10-30 DEG C of solarization 0.5-1 hour, and turn back in the process of scanning.
Concrete, in the present embodiment, owing to all can containing some harmful medicines to environment in waste water at different levels, and these medicines mostly are the medicine of easy degraded, and in order to be realized the degraded of fast speed, preferably, after waste water at different levels is concentrated respectively, shine 0.5-1 hour at 10-30 DEG C, by the operation of being exposed to the sun, can reach the effect of fast degradation, and then better turn back in flow processs at different levels.
In addition, in above-mentioned operation, concentrate and refer to: waste water at different levels can be pooled in preprepared storage cistern, and all arrange separately for the cistern of collecting different waste water, in order to avoid waste water mixes, and then overcome while turning back in beneficiation flowsheet, the contained medicine of different waste water causes adverse effect to different beneficiation flowsheets.
In addition, need be pointed out that, in above-mentioned steps concentrated, it specifically refers to different ore deposits (mine tailing, copper concentrate or molybdenum concntrate) use successively concentrator, ceramic filter dehydration.By the waste water obtaining after the dehydration of concentrator, ceramic filter, its well removed contained solid particle with and and impurity, and then can better recycle.
More specifically, comprise at described concentrator: traction thickener or center driving thickener.
In the present embodiment, the operation that uses for a long time waste water (the first waste water, the second waste water, the 3rd waste water) to return to parent job may cause some fine fraction gangues and floating agent to gather, and then affects copper molybdenum production target, causes its grade to reduce.In order to address this problem, copper-molybdenum after flotation is being separated and roughly selected, obtain molybdenum rough concentrate and roughly selecting in the process of rear mine tailing, utilize and add clear water (possessing certain pressure) and then realize the effect of rinsing, and then the grade of the molybdenum rough concentrate that ensures to know clearly.
In addition, after adopting cyclone to carry out flotation in copper molybdenum detached job (separation is roughly selected), copper-molybdenum carries out desliming, in advance fine fraction gangue is removed, solve fine fraction gangue in backwater copper molybdenum has been separated to bring unfavorable, optimize flotation environment, ensure that molybdenum concntrate reaches qualified products, obtained good economic effect.
The foregoing is only the preferred embodiments of the present invention, be not limited to the present invention, for a person skilled in the art, the present invention can have various modifications and variations.Within the spirit and principles in the present invention all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
