Abstract
The invention discloses a method for utilizing return water of separation flotation for copper and molybdenum bulk concentrates. The method includes that overflow water of a copper concentrate thickener used during separation for the copper and molybdenum bulk concentrates is used as pulp regulating water for copper and molybdenum bulk concentrates after reagents in the copper and molybdenum bulk concentrates are removed, and is fed into a copper and molybdenum separation flotation process; copper concentrates acquired after copper is separated from molybdenum are fed into the thickener to be thickened, the overflow water is fed into a pulp storage tank, and is fed into a copper and molybdenum bulk concentrate pulp regulating tank by sand pump, pulp is regulated by the overflow water and copper and molybdenum bulk concentrate filter cakes, and obtained pulp is used as crude ore for copper and molybdenum separation flotation and is fed into a copper and molybdenum separation process. The return water generated during copper and molybdenum separation can be effectively utilized by the method, discharge of mineral processing wastewater can be reduced, and the copper and molybdenum separation return water can be treated. Compared with other methods for treating copper and molybdenum separation return water, the method has the advantages of simple technological processes, convenience in operation, stability in processes and the like.
Description
Technical field
The invention belongs to technical field of mineral processing, relate to a kind of method of utilizing of copper molybdenum bulk concentrate separating flotation backwater.
Background technology
In copper molybdenum bulk concentrate separating flotation process, in order to reach effective separation of copper molybdenum, need add collecting agent kerosene, dispersant waterglass and a large amount of inhibitor NaHSs etc.The suspended substance that in these floating agents and catabolite thereof and mineral, the metal ion of corrosion, mineral subparticle form etc. all will remain in flotation backwater.Directly discharge not only makes the not floating agent of effect loss in flow process, and makes harmful substance in backwater pollute local environment.Therefore, in sorting index situation, use to greatest extent backwater not affecting, effectively utilize residual pharmacy in backwater simultaneously, reduce new medicament consumption and backwater discharge capacity.Solve mineral processing production short water supply, improve ore dressing recycling water utilization.
The separated backwater of copper molybdenum bulk concentrate is processed and is mainly contained three kinds: the one, and backwater returns after treatment and selects factory's production procedure.The 2nd, directly enter Tailings Dam and mix with bulk flotation tailing water as large backwater and return to copper molybdenum bulk flotation flow process.The 3rd, directly return to copper molybdenum bulk flotation flow process.
The separated backwater of copper molybdenum is processed the general oxidizing process that adopts, and first oxidation of ore pulp is through Separation of Solid and Liquid, and contained thiosulfate in overflow water, according to Fenton procedure method hydrogen peroxide oxidation, can all be converted into sulfate, finally with white lime, neutralizes.Direct complex treatment process, workman's operation easier is large, increases beneficiation cost.The separated backwater of copper molybdenum directly enters Tailings Dam to be mixed and has increased the mine tailing water yield with bulk flotation tailing water, and Tailings Dam can not bear free sulfhydryl ion degradation products, be mainly sulfur-bearing salt, continue to be oxidized to SO
4 =the acid needs that produce and bulk flotation tailing water fully mix after natural sedimentation can return to bulk flotation flow process, and directly discharge not only brings storage pressure, contaminated environment and causes metal loss to Tailings Dam; The separation of copper molybdenum bulk concentrate adds a large amount of inhibitor NaHSs, directly returns to copper molybdenum bulk flotation flow process and can produce certain inhibitory action to copper mineral, affects bulk flotation index.
Summary of the invention
The object of the invention is to provide a kind of method of utilizing of copper molybdenum bulk concentrate separating flotation backwater; the separated backwater that produces of copper molybdenum bulk concentrate is used without processing in direct Returning process; solve mineral processing production short water supply, improve ore dressing recycling water utilization; save new water consumption, be for making full use of water resource, reduce discharge of wastewater, the new measure of energy-saving and cost-reducing, protection of the environment, raising ore dressing whole economic efficiency.
The present invention enters copper molybdenum separating flotation flow process using the water of sizing mixing after the reagent removal of copper molybdenum bulk concentrate of copper concentrate concentrator overflow water in the separation of copper molybdenum bulk concentrate; The separation of copper molybdenum obtains copper concentrate, and to enter concentrator dense, and overflow water enters slurry storage tank, by sand pump, feeds copper molybdenum bulk concentrate surge tank and copper molybdenum bulk concentrate filter cake is sized mixing, and as copper molybdenum separating flotation raw ore, feeds copper molybdenum separation process.
Beneficial effect of the present invention:
The present invention can effectively use the separated backwater that produces of copper molybdenum, reduces beneficiation wastewater discharge, has solved the separated water treatment problems of returning of copper molybdenum.Process the separated water return method of copper molybdenums with other and compare, it is simple that the present invention has technological process, convenient operation, the advantage such as flow process is stable.
The specific embodiment
The present invention enters sand pump pond by the separated copper concentrate producing of copper molybdenum through sand pump, to feed concentrator dense, concentrator overflow water enters slurry storage tank and feeds copper molybdenum bulk concentrate surge tank by sand pump, after sizing mixing with copper molybdenum bulk concentrate filter cake, by sand pump, feed the separated raw ore slurry storage tank of copper molybdenum, then feed copper molybdenum shunting flotation flowsheet by sand pump.Technological process of the present invention is simple, simple to operate and copper molybdenum Separation Indexes is better.
Example
Comparison of test results that certain copper molybdenum bulk concentrate clear water is sized mixing and backwater is sized mixing
Table 1: clear water and backwater are respectively as sizing mixing water test result
Result of the test shows: when with backwater when sizing mixing water, molybdenum concentrate grade and copper content can be under some influence, but Molybdenum Concentrate Grade is completely qualified.And test show can obviously reduce inhibitor NaHS consumption when test with backwater, the present invention obtains good result in the application of Mou Tongmuxuan factory, actual production shows to reduce discharge of wastewater, minimizing NaHS consumption 1/4 left and right.Obtain better economic benefit.
