The application is described in further detail below in conjunction with specific embodiment, these embodiments are it is not intended that limit this
Apply for scope claimed.
As described by background section, in the prior art for the processing technological flow of smelting slag after copper weld pool
Length, occupation area of equipment is big, cost is high.
In order to solve this problem, the invention provides a kind of copper smelting apparatus, as shown in figure 1, copper smelting apparatus is set
There is inner chamber, inner chamber includes smelting zone 10, stripping section 20 and decanting zone 30；Smelting zone 10 to copper concentrate carry out melting with life
Into the first copper matte regulus and smelting slag；Stripping section 20 is separated with smelting zone 10 by the first partition wall 11, stripping section 20 and smelting zone 10 it
Between connected by smelting slag passage, and stripping section 20 is used to carry out smelting slag dilution processing to generate the second copper matte regulus and dilution
Slag；Decanting zone 30 is separated with stripping section 20 by the second partition wall 12, and decanting zone 30 is located at the remote smelting zone 10 of stripping section 20
Side, connected between decanting zone 30 and stripping section 20 by poor slugging passage, decanting zone 30 be used for the second copper matte regulus and dilution
Slag carries out sedimentation separation.
Above-mentioned copper smelting apparatus is the integration apparatus of a stove multicell, at copper weld pool process and smelting slag dilution, sedimentation
Reason process is concentrated in a stove and carried out.In actual application, copper concentrate can carry out melting, output in smelting zone 10
One copper matte regulus (high-grade copper matte regulus) and smelting slag, smelting slag pass through the first partition wall 11 through stove, and smelting slag passage flow to stripping section 20.
Smelting slag after dilution is handled can the copper matte regulus of output second (low-grade copper matte regulus) and poor slugging, further pass through poor slugging passage enter
Decanting zone 30 carries out sedimentation separation, and the second copper matte regulus and poor slugging are more fully separated, and makes copper in the slag that finally gives
Content is lower, can be directly as waste.
Copper weld pool is carried out using said apparatus provided by the invention, directly can be concentrated on melting, dilution and sedimentation separation
One stove, it can realize in the case of output high-grade copper matte regulus while obtain the very low waste of copper content.And use a stove multi zone furnace
Body structure type, process is few, and technological process greatly shortens, and floor space is few, reduced investment, cancels slag slow cooling and slag beneficiating process,
Reduce material to have bad luck, save a large amount of human and material resources, labour cost is low, improves production efficiency, high financial profit.Therefore, this hair
Bright device is ingenious in design, reasonable, energy-saving and environmental protection, green, has good value for applications.
Herein it should be noted that during dilution, the second copper matte regulus and poor slugging are generated, poor slugging can carry part
Second copper matte regulus enters sedimentation separation from poor slugging passage.So-called sedimentation separation is actually the part by poor slugging and its carrying
Second copper matte regulus carries out sedimentation separation.In addition, in actual application, copper concentrate is carried out to the process of melting in smelting zone 10
In, some Gold Concentrate under Normal Pressure can also be added, during copper weld pool by gold and silver melting into the first copper matte regulus, follow-up need to be by ability
The usual electrolysis mode in domain separates gold and silver with copper.Gold Concentrate under Normal Pressure is added from smelting zone rather than added from stripping section, so
The gold and silver loss taken away from decanting zone waste can be reduced, improves the rate of recovery of gold and silver.
In a preferred embodiment, in above-mentioned inner chamber, smelting zone 10 and stripping section 20 are set respectively in the horizontal direction
Put in the both sides of the first partition wall 11, decanting zone 30 and stripping section 20 are separately positioned on the both sides of the second partition wall 12 in the horizontal direction.
So, smelting zone 10, stripping section 20, the chamber of decanting zone 30 3 are horizontal arrangement, with continuous charging melting, are produced after smelting
Raw smelting slag directly can be from flowing into stripping section 20, and poor slugging caused by dilution processing can also be from inflow decanting zone 30
Complete the separation of copper matte regulus and slag.
In a preferred embodiment, the bottom wall positioned at the lower section of the second partition wall 12 of inner chamber is inclined plane, and along poor
Change area 20 to the direction away from stripping section 20, inclined plane to be inclined upwardly.In this way, poor slugging and the second copper matte regulus are in decanting zone 30
After middle completion sedimentation separation, the second copper matte regulus conveniently can be concentrated the second copper matte regulus along inclined plane from flowing back in stripping section 20
Discharge.
First copper matte regulus of the above-mentioned output of smelting zone 10 is high-grade copper matte regulus, and the second copper matte regulus of the output of stripping section 20 is low-grade
Copper matte regulus, the two can be discharged respectively, can also concentrate discharge.Specifically：

Into ledge structure, and the depth of smelting zone 10 is more than the depth of stripping section 20；The bottom of smelting zone 10 is provided with copper matte regulus outlet.This
Sample, the second copper matte regulus can mix by ledge structure from flowing into smelting zone 10 equivalent to by high-grade copper matte regulus and low-grade copper matte regulus
Concentrated after conjunction from the copper matte regulus of the bottom of smelting zone 10 and export perforating or siphon discharge.
Preferably, in said apparatus, the height of ledge structure is 500~1200mm, so in continuous running,
The thickness of first copper matte regulus layer of the bottom of smelting zone 10 can reach 500~1200mm, and the second of stripping section 20 and the bottom of decanting zone 30
The very thin thickness of copper matte regulus layer, is 0~300mm, 100~1200mm of thickness of slag layer in region.Made using the gravity flow of the second copper matte regulus
With reaching the purpose of the stable discharging of copper matte regulus.
As shown in Fig. 2 in another preferred embodiment, inner chamber is gone back on the bottom wall of the lower section of the first partition wall 11
Bulge-structure is provided with, smelting slag passage is formed between bulge-structure and the first partition wall 11；The bottom of smelting zone 10 is provided with
One copper matte regulus exports, and the bottom of stripping section 20 is provided with the outlet of the second copper matte regulus.So, can be respectively by the first copper matte regulus and the second bronze medal
Sulfonium is discharged from copper smelting apparatus.It is convex or being located on the bottom wall of the lower section of the first partition wall 11 for inner chamber is additionally provided with bulge-structure
Rise and smelting slag passage is formed between structure and the first partition wall 11；The bottom of smelting zone 10 is provided with copper matte regulus outlet.So, with dressing
The continuous production put, the second copper matte regulus is cumulative in the bottom of stripping section 20, may finally enter across raised overflow in smelting zone 10,
