Abstract
The invention relates to a treatment method of turbid underflow in a novel liquid storing tank used in zinc smelting. The invention belongs to the technical field of non-ferrous metal smelting. When novel liquid storing tanks are used alternatively, a novel liquid pumping outlet valve is controlled, and novel liquid turbid underflow is pumped into a waste liquid storing tank of a leaching system; the step is proceeded for 5-10min; the novel liquid pumping outlet valve is controlled, and the novel liquid is pumped into a mixed liquid tank, and is delivered into an electrolysis system. The method provided by the invention is advantaged in that: the novel liquid delivered into the mixed liquid tank does not contain impurity, such that the electrolysis system is more stable; valuable metals are recycled, such that resource is effectively saved, and cost is reduced.
Description
Technical field
The present invention relates to a kind of zinc that is used for and smelt the treatment process that zinc is smelted the muddy underflow of new liquid storage tank, belong to the non-ferrous metal metallurgy technical field.
Background technology
80% enterprise adopts wet method in the present domestic zinc smelting technology; The new general the using and the reserved of liquid storage tank in zinc hydrometallurgy; Underflow of cleaning in each storage tank 3-4 month; Avoid because of using the muddy new liquid in new liquid storage tank bottom to cause electrolytic solution to contain assorted the rising, electrolysis process produces fluctuation, causes electrolytic zinc quality and output to descend.Yet in normal productive process; Two phenomenons that new liquid storage tank is used alternatingly often occur, so just be difficult to avoid when just being used alternatingly, can use the muddy new liquid underflow of a part; Owing to contain higher impurity in the muddy new liquid underflow, will cause the electrolysis process fluctuation.
Summary of the invention
The objective of the invention is to overcome the deficiency of the underflow that can use the muddy new liquid of a part when two new liquid storage tanks are used alternatingly in the prior art; And provide a kind of zinc to smelt the treatment process of the muddy underflow of new liquid storage tank; When being used alternatingly new liquid storage tank; Through controlling new liquid pump outlet valve the muddy underflow of new liquid is squeezed into the waste water storage tank of leaching system, continue after 5-10 minute, new liquid is squeezed into mixed liquid bath and get into electrolytic system through controlling new liquid pump outlet valve.The invention has the advantages that the new liquid of squeezing into the mixing liquid bath is free from foreign meter, electrolytic system is more stable; Reclaim valuable metal, effectively saved resource, reduced cost.
Realize like this during technical scheme of the present invention:
A kind of zinc is smelted the treatment process of the muddy underflow of new liquid storage tank, and the step of this method is following:
Described a kind of zinc is smelted the treatment process of the muddy underflow of new liquid storage tank; Contain crystalline compounds zinc, magnesium, calcium in the new liquid liquid of the muddy end; With this part new liquid squeeze into invade out system's waste water storage tank after; Because waste liquid acidity is at 140-170g/L in the waste water storage tank, can utilize the acidity of itself that the dissolving of the valuable metal in the new liquid underflow is reclaimed.
Beneficial effect of the present invention:
When new liquid is not used in new liquid storage tank; Along with quiet prolongation of putting the time; The more inner impurity of new liquid can slowly fall to new liquid storage tank bottom, and the muddy and impure amount of new liquid underflow is increased, when being used alternatingly new liquid storage tank; The muddy new liquid underflow that impure amount is many no longer gets into electrolytic system, and electrolytic system technology is more stable.
Description of drawings
A kind of zinc of the present invention is smelted the treatment process process flow sheet of the muddy underflow of new liquid storage tank during Fig. 1.
Embodiment
A kind of zinc is smelted the treatment process of the muddy underflow of new liquid storage tank, and the step of this method is following:
Contain crystalline compounds zinc, magnesium, calcium in the described new liquid liquid of the muddy end; With this part new liquid squeeze into invade out system's waste water storage tank after; Because waste liquid acidity is at 140-170g/L in the waste water storage tank, can utilize the acidity of itself that the dissolving of the valuable metal in the new liquid underflow is reclaimed.
Claims (2)
1. a zinc is smelted the treatment process of the muddy underflow of new liquid storage tank, and it is characterized in that: the step of this method is following:
Step 1 is closed waste liquid valve (9), new fluid valve (3), and in new liquid storage tank (1), adds the new liquid of capacity, quiet then putting;
Step 2; After treating that some inner impurity of new liquid slowly fall to new liquid storage tank bottom; Open waste liquid valve (9), start new liquid pump (2) and from new liquid storage tank (1), extract the muddy underflow of new liquid and be injected into waste water storage tank (8) through the waste liquid valve of opening (9);
Step 3; Continue from new liquid storage tank (1), to extract the muddy underflow of new liquid after 5-10 minute; Close waste liquid valve (9), open new fluid valve (3), utilize new liquid pump (2) from new liquid storage tank (1), to extract new liquid and also new liquid is injected in the mixing liquid bath (4) through new fluid valve (3);
Step 4 is opened mixture pump (5) and will be mixed mixed solution in the liquid bath (4) and be injected in the electrolytic system (6) and carry out electrolysis, and the waste liquid that produces after the electrolysis gets in the waste water storage tank (8) through waste drains pump (7).
2. zinc according to claim 1 is smelted the treatment process of the muddy underflow of new liquid storage tank; It is characterized in that: contain crystalline compounds zinc, magnesium, calcium in the new liquid liquid of the muddy end; With this part new liquid squeeze into invade out system's waste water storage tank after; Because waste liquid acidity is at 140-170g/L in the waste water storage tank, can utilize the acidity of itself that the dissolving of the valuable metal in the new liquid underflow is reclaimed.
