Background technology
The method being electrolysed with pyrogenic process is reclaimed in the smelting process of noble metal in lead, the Copper making by-product earth of positive pole, for melting
New furnace lining is changed after must being removed after for a period of time with the converter lining of blowing, the furnace lining changed due to being immersed in for a long time
In high temperature precious metal melt, infiltration has the noble metals such as gold, silver in furnace lining, and reclaiming this part noble metal has preferably reality meaning
Justice, can create good economic benefit.
At present, the method that noble metal is reclaimed from the useless brick of converter has the de- lead-nitric acid point of gravity treatment-sulfuric acid de-magging-alkali cleaning
Silver-chloroazotic acid Method for extracting gold.The method acid consumption is big, and a large amount of smelting wastewaters of output, economic benefit is low.
The content of the invention
The purpose of the present invention is directed to the problem that above-mentioned prior art is present, and proposes that a kind of useless brick of converter reclaims the side of gold and silver
Method, the method can the noble metal, remarkable in economical benefits such as low consumption, the efficient gold and silver reclaimed in useless brick.
The purpose of the present invention is realized by the following means:
The method that a kind of useless brick of converter reclaims gold and silver, comprises the following steps:
(1)After converter lining is split out, manual sorting goes out to be flooded by molten bath the useless brick of part;
(2)By step(1)The useless brick crusher in crushing for obtaining, the useless brick ball mill fine grinding after crushing obtains useless brick powder, so
It is milled to below 200 mesh with grinder afterwards;
(3)By step(2)The method of the useless brick powder flotation below 200 mesh for obtaining selects the concentrate rich in gold and silver;
(4)By step(3)The concentrate and lead anode slurry for obtaining are by 1:After sodium carbonate, reduction coal, iron filings, stone flour being allocated into after 2 collocation
It is well mixed;
(5)By step(4)Material input precious metals containing lead stove melting after well mixed, output precious metals containing lead, shoddye and flue dust;
(6)By step(5)The precious metals containing lead input point silver stove blowing for obtaining, output electrum, lead skim, bismuth slag and flue dust.
(7)By step(6)The electrum for obtaining energization electrolysis in the aqueous solution of nitric acid and silver nitrate obtains silver powder, residual
Pole and silver anode slime;
(8)By step(7)The silver powder founding for obtaining is into silver ingot product;
(9)By step(7)Silver separating residues are obtained after the silver anode slime nitric acid for obtaining point silver;
(10)By step(9)The silver separating residues for obtaining aqueous solution chlorination method parting, the method that parting solution is reduced with sodium sulfite
Reclaim gold;
(11)By step(10)The gold for obtaining founding after nitric acid washout impurity into ingot product.
The present invention will permeate noble metal useless brick sort out after carry out fine grinding, it is levigate after useless brick powder floated
Choosing, will put into stove melting after the concentrate obtained by flotation and lead anode slurry collocation, floating using the effectively trapping of the lead in lead anode slurry
Gold and silver in concentrate selection.The present invention does not increase smelting wastewater amount, and sour consumption is not increased, and method is simple and reliable, efficient to reclaim useless brick
In the noble metal, remarkable in economical benefits such as gold and silver.
