Abstract
The invention discloses a method for chemical copper removal of wet lead and belongs to the field of non-ferrous metals. The method comprises the following steps: (1) preparing a solution; (2) adjusting temperature; (3) adding reactants; (4) controlling reaction; and (5) performing slag removal. By adopting the method disclosed by the invention, the problems that in a subsequent copper removal process of the existing wet lead smelting, copper cannot be completely removed very effectively and the copper content of lead is too high are solved; and the method is simple, low in cost and easy in processing.
Description
Technical field
The invention belongs to non-ferrous metal field, more particularly, relate to a kind of method for lead bullion decopper(ing).
Background technology
Lead is widely used industrial at present, especially maximum at electrical industry department consumption, is mainly used to manufacture store battery, various cable protection skin, fuse wire etc.Stereotype and lead pipe are often done to smelt and chemical industry equipment antiseptic acidproof lining, corrosion cap, plumbous protective layer and the protective shield being also used as nuclear industry and X-ray.Plumbous compound is used for pigment industry, glass industry, petroleum industry and medical department etc.But lead is in the process of processing refinement, containing objectionable impuritiess such as copper, in the subsequent handling of lead smelt, need copper to go out, to improve plumbous purity.
Summary of the invention
Remove in copper process for the follow-up of existing lead smelt, very effectively copper can not be removed completely, and the problem causing plumbous copper content too high, the invention provides a kind of chemical copper-removing method of lead bullion, by adding sulphur and control its temperature in lead solution, make it that chemical reaction occur, thus reach the object of copper.
For solving the problem, the present invention adopts following technical scheme.
A chemical copper-removing method for lead bullion, comprises the following steps:
(1) preparation of solution:
Lead bullion solution is released from blast furnace, and is transported in liquation decoppering pot by containing lead pan;
(2) temperature regulates:
The temperature of lead solution is controlled within the scope of 600-640K;
(3) interpolation of reactant:
Powdery sulphur is joined in liquation decoppering pot;
(4) reaction controlling:
Mechanical stirring device is utilized to stir, to accelerate its chemical reaction;
(5) remove the gred:
Utilize the vulcanized slag removing that slag removal equipment will float on lead solution.
Preferably, in described step (2), the temperature of lead solution is controlled within the scope of 610-620K.
Compared to prior art, beneficial effect of the present invention is:
(1) the present invention adds powdery sulphur in lead solution, and sulphur and lead are reacted generation lead sulfide, and copper and lead sulfide generation replacement(metathesis)reaction, thus lead is displaced, and copper is precipitated with the form of compound, reach the object of copper, and make the level that its copper content reaches lower.
(2) the inventive method is simple, and cost is low, handling ease.
Embodiment
Describe the present invention below in conjunction with embodiment.
