Abstract
The invention relates to a method for removing thallium in a zinc hydrometallurgy solution purification process. The method includes: preparing a 200-800g/L lead acetate solution, adding the prepared lead acetate solution into a solution purification tank to remove thallium, after thallium removal reaction, carrying out liquid-solid separation, and letting thallium enter slag. The method provided by the invention does not extend the production period and also does not increase additional equipment investment, the cost is low, and the effect is good.
Description
Technical field
The present invention relates to a kind of method except thallium in zinc hydrometallurgy solution purification.
Background technology
In Zinc Hydrometallurgy Process, thallium is very harmful to zinc hydrometallurgy electrolyting precipitation process, easily causes serious " burning plate ", and bring out other impurity " burning plate ", product production and technical-economic quota index are had a negative impact, causes the continuous fluctuation of producing, cannot normally carry out.In zinc hydrometallurgy solution purification, in order to remove thallium, need process control condition be improved, increase zinc consumption simultaneously, except thallium effect is difficult to be guaranteed.
Summary of the invention
The object of the present invention is to provide a kind of method except thallium in zinc hydrometallurgy solution purification, do not affect the technology controlling and process of solution purification, guarantee except thallium effect simultaneously.
For achieving the above object, technical solution of the present invention is: in zinc hydrometallurgy solution purification, add plumbic acetate, and the thallium in removing solution, is characterized in that following steps:
A, configuration concentration are the plumbic acetate solution of 200-800g/L;
B, the plumbic acetate solution of steps A being joined, join in solution purification groove except thallium;
C, except thallium reaction after carry out solid-liquor separation, thallium enters in slag.
Further, in described B the add-on of plumbic acetate solution in following ratio: every 100m
3the plumbic acetate amount of solution of 10-50L is added in solution purification amount.
The invention has the beneficial effects as follows: 1, in zinc hydrometallurgy solution purification, add plumbic acetate that the thallium in removing solution does not need to increase the other reaction times, synchronously carry out with former technique, can not extend manufacture cycle, also can not increase extra facility investment, cost is low, effective; 2, the technology controlling and process of zinc hydrometallurgy solution purification is not affected, be conducive to the valuable metal grade reducing zinc powder consumption and increase purification slag; 3, after purification, solution is 0.00008-0.0003g/L containing thallium, meets the requirement of electrolysis completely, can not cause " burning plate " in process in zinc electrolyzing because of thallium.
Embodiment
Below in conjunction with example, the invention will be further described.
Plumbic acetate solution needed for preparation, its plumbic acetate concentration is 300g/L; In zinc hydrometallurgy solution purification, its solution flow is 300m
3/ h; In solution purification technological process, control normal except cadmium temperature, reactor time, zinc powder add-on; Add configured plumbic acetate solution, adding inbound traffics is 30L/h; Carry out except thallium reaction, carry out solid-liquor separation after reaction, thallium enters in slag, and solution is 0.0002g/L containing thallium, meets the requirement of electrolysis completely, can not cause " burning plate " in process in zinc electrolyzing because of thallium.
The present invention adds plumbic acetate except thallium in zinc hydrometallurgy solution purification, and not needing increases the other reaction times, and synchronously carry out with former technique, can not extend manufacture cycle, also can not increase extra facility investment, cost is low, effective.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
Claims (2)
