Abstract
The invention discloses an oxidation refining method of lead bullion and belongs to the field of non-ferrous metals. The oxidation refining method comprises the following steps: (1) preparing a solution; (2) introducing oxygen; (3) controlling the temperature; and (4) removing slag. By the oxidation refining method, the problem that the purity of the lead is decreased since impurities such as Zn, Sn, As and Sb cannot be effectively removed in the existing lead bullion smelting process is solved and the oxidation refining method has the advantages of being simple in process, low in cost and easy to process.
Description
Technical field
The invention belongs to non-ferrous metal field, more particularly, relate to a kind of method for the refining of lead bullion.
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 impurity such as Zn, Sn, As, Sb, reduce plumbous purity, belong to objectionable impurities, need to manage it to remove from lead.
Summary of the invention
In process for existing lead smelt, can not effectively by impurity removings such as Zn, Sn, As, Sb, thus reduce the problem of plumbous purity, the invention provides a kind of oxidation refining method of lead bullion, utilize the method for oxidation by each oxidation of impurities, obtain the oxide compound being insoluble to lead solution, thus be isolated, reach the object improving plumbous purity.
For solving the problem, the present invention adopts following technical scheme.
An oxidation refining method for lead bullion, comprises the following steps:
(1) preparation of solution:
Lead bullion solution is released from blast furnace, and is transported in reverberatory furnace by containing lead pan;
(2) oxygen is passed into:
Be input to bottom reverberatory furnace by oxygen by conduit, oxygen delivery speed is 4-6L/ (min ﹒ m
3);
(3) temperature controls:
Lead solution temperature is controlled in the scope of 700-750K;
(4) remove the gred:
Utilize the oxidation sludge removing that slag removal equipment will float on lead solution.
Preferably, in described step (2), oxygen delivery speed is 5L/ (min ﹒ m
3).
Preferably, in described step (3), lead solution temperature is controlled in the scope of 720-730K.
Compared to prior art, beneficial effect of the present invention is:
(1) the present invention passes into oxygen in lead solution, makes each oxidation of impurities, obtains the oxide compound being insoluble to lead solution, thus is isolated, and plumbous purity is improved.
(2) the inventive method is simple, and cost is low, handling ease.
