Abstract
The invention relates to a method for producing blister copper, according to which method copper concentrate (5), flux (6) and oxygen-enriched air (7) are fed together into a suspension smelting furnace (1), such as a flash smelting furnace, so that there are created at least two molten phases, such as a white metal phase (11) and a slag phase (10); and that the white metal is oxidized after the suspension smelting furnace in at least one oxidizing reactor (12).
Description
The present invention relates to a kind of method of producing blister copper, according to this method, the air (7) of copper ore concentrates (5), fusing assistant (6) and oxygen enrichment is sent into flash smelting furnace (1) together, so that generate at least two fusion phases, after flash smelting furnace, white metal oxidation at least one oxidation reactor (12) is characterized in that, in flash smelting furnace (1), the oxygen gesture is 10
-7-10
-6, and the dividing potential drop of sulfurous gas is 0.2-1, is connected with flash smelting furnace (1) and oxidation reactor (12) is set.。
In the flash smelting of copper, the exsiccant copper ore concentrates is sent in the flash smelting furnace with the air and the silica sand of oxygen enrichment.Energy required in fusion process obtains in the oxidation of sulphur and iron.Regulate the thermal equilibrium of described method by the degree of enrichment of process air, but also use oil or natural gas burner to be used as the other energy sometimes.The sulphur oxidation generates sulfurous gas, and iron oxidation and slagging generate ferric metasilicate.In settling vessel, fusion along with slag and matte settlement on furnace bottom with described gas delivery so that the sulfonium layer is at bottommost.In flash smelting, in the copper smelting process at other, the major function of slag is to collect with the fluidic form, discharges all ferric oxide and the silicate composition and the oxide components of the gangue that produces in fusion process.Usually, slag is cooled, fragmentation and flotation, so that reclaim copper, perhaps it is handled in the electric reduction furnace method.Sulfonium mutually in, its is conversion processing usually further, makes the copper of 50-70%.In the most normally used Peirce-Smith converting, when oxygen blast in melt, the mutually contained iron of sulfonium is oxidized, and generating the fajalite slag with the silica sand that adds, the latter floats in reactor on the surface of rich copper bearing white metal (whitemetal) in the initial step of conversion process.White metal contains 70-80% copper.When further oxygen being blown into white metal, generate blister copper, its copper content is about 99%.Slag also contains the copper of 5-10%, and it is with flotation process and by the copper bearing slag concentration thing of richness being returned flash smelting furnace or reclaiming by for example handle slag under reductive condition in electric furnace.
In principle, the direct production blister copper is reasonably economically, just, produces blister copper with a processing step from the sulfurized concentrate in suspension reactor, has some restriction certainly.Here Zui Da problem is in described method, generate a large amount of slags, and a large amount of copper concentrates on also in this slag.On the other hand, in order to reclaim wherein contained copper, the processing of slag needs extra-pay.When the copper content in the concentrate was enough high, at least 37% (weight) was favourable with a processing step production blister copper economically usually.If concentrate only contains a spot of iron or other generate the component of slag, so in this case, the quantity that generates slag can be so not high, and the processing of the concentrate of low copper content also is favourable.When producing blister copper,, need carry out two step slags usually to the slag that generates and purify in order to obtain the productive rate of sufficiently high recovery copper.
According to prior art, when in certain oxygen gesture scope, operating, in the copper melting, generate so-called white metal, in this case, the copper content of respective slag phase is significantly less than the situation that blister copper and slag balance each other.At Fig. 1 (INSKO 261608VIII, the 9th page), Cu-Fe-S-O-SiO has been described
2Sulphur-oxygen gesture the figure of system under 1300 ℃.In the drawings, see the out of phase content that in the copper fusion process, under different condition, occurs.As can be seen from the figure, when white metal existed, the copper content of respective slag was lower than and blister copper equilibrated slag.
From PCT 00/09772 known a kind of in the presence of the oxygen by oxidation concentrate or the sulfonium method of coming smelting copper concentrates continuously under 1300 ℃ or lower temperature.According to this method, copper sulfide concentrate is melted, and contained most of iron is removed as slag, and most of sulphur changes into sulfurous gas.The product that makes is white metal, sulfonium or blister copper.
The objective of the invention is to overcome shortcomings more of the prior art.Another object of the present invention is the slag that prevents to produce high copper content in blister copper is produced.
Of the present invention being characterized by in the following technical scheme:
