Electrode 7 energisings are to improve the melt temperature in the burner hearth.Simultaneously, in burner hearth, spray into oxygen by oxygen lance 6 from the bottom of body of heater 1, and in burner hearth, spray into the mist of carbon monoxide and nitrogen by carbon monoxide entrance 15a and nitrogen entrance 15b from the bottom of body of heater 1.Certainly, also can in burner hearth, spray into carbon monoxide from the bottom of body of heater 1, and in burner hearth, spray into nitrogen from the bottom of body of heater 1 by nitrogen entrance 15b by carbon monoxide entrance 15a.
A part of sulphur in the vulcanizing agent and oxygen reaction generate SO
2, the CuO reaction in a part of sulphur and the slag generates SO
2And CuS, make the copper that exists with the CuO form in the smelting slag obtain reclaiming the Fe in some sulphur and the slag thus with the form of copper matte regulus
3O
4Reaction generates SO
2And FeS, S and Fe
3O
4The FeS that reaction generates enters copper matte regulus, has reduced the grade of copper matte regulus.
Based on 1: 100 cupric distribution ratio between slag and copper matte regulus, utilize the utility model body of heater to carry out the copper matte regulus grade that dilution obtains and reduce, the cupric of copper matte regulus＜35% for example, thus reduce copper content in the waste, for example the copper content in the waste has reduced the copper amount that abandons with waste thus less than 0.4%.
In addition, because a part of sulphur and Fe
3O
4Reaction has reduced the Fe in the slag
3O
4Content, thereby the viscosity and the fusing point of reduction slag, sedimentation from slag enters copper matte regulus with separating with CuS to help Cu, has improved the rate of recovery of copper.
And, the Fe in carbon monoxide and the copper smelting slag
3O
4Reaction generates carbon dioxide and FeO, has further reduced the Fe in the slag in the burner hearth
3O
4Content, further reduce the viscosity and the fusing point of slag, sedimentation from slag enters copper matte regulus with separating with CuS to help Cu, improves copper recovery.
In addition, carbon monoxide and CuO participate in reaction and generate carbon dioxide and Cu, increase its proportion, can increase the sedimentation separation speed of copper matte regulus, have improved efficient.
In the process that in the slag of nitrogen in burner hearth, rises, have certain agitaion, the polymerization of particulate cupric material is grown up, quicken sedimentation and separate with waste.Simultaneously, nitrogen increases CuO and contacts, collides with CuS in uphill process, produces cross reaction, generates Cu and SO2, also helps copper sedimentation separation from slag and enters copper matte regulus, reaches the purpose of further reduction waste cupric, improves the rate of recovery of copper.And the carbon monoxide that sprays into also has certain agitaion, thereby can play the effect identical with the nitrogen that sprays into.
Thus, copper in the copper smelting slag is deposited to burner hearth bottom with the form of copper matte regulus and separates with waste, and because the grade of copper matte regulus is low, thereby can reduce the copper content of waste, copper matte regulus is discharged burner hearth by the siphon port on the body of heater 1 12, and the waste above the copper matte regulus is discharged burner hearth by waste floss hole 13.
When after using after a while, needing to change oxygen lance or maintenance, can blowing out, and by drive unit 5 rotating furnace body 1 in the scopes of 90 degree, thereby be convenient to change oxygen lance and or maintenance operation.
Although illustrated and described embodiment of the present utility model, those having ordinary skill in the art will appreciate that: can carry out multiple variation, modification, replacement and modification to these embodiment under the situation that does not break away from principle of the present utility model and aim, scope of the present utility model is limited by claim and equivalent thereof.
