In a preferred embodiment, in the step of copper concentrate to be carried out to melting in smelting furnace, the first oxidant
Straying quatity for copper concentrate per ton correspondence 120Nm3Above O2So that the copper content of the first copper matte regulus is more than or equal to 70wt%.By
The straying quatity control of one oxidant is copper concentrate per ton correspondence 120Nm3Above O2, can make the first copper matte regulus copper content be more than
Equal to 70wt%, it can so avoid making the problem of Cu-S ore amount is bigger than normal caused by the copper content of the first copper matte regulus is too low, prevent
The problem of copper direct yield brought by it is low.More preferably the straying quatity of the first oxidant be copper concentrate per ton correspondence 120~
200Nm3O2So that the copper content of the first copper matte regulus is 70~78wt%, this can further be avoided the copper content mistake because of the first copper matte regulus
Caused by high smelting slag copper containing it is too high the problem of, the problem of preventing the copper direct yield that therefore brings low.In addition, copper matte regulus cupric is 70
When~78%, the element such as lead zinc antimony enters smelting slag in the form of an oxide, is conducive to subsequently reclaiming these elements from CR stoves.If copper
Sulfonium cupric is low, and when such as 40~50%, a part for these elements can be stayed in copper matte regulus, is unfavorable for follow-up from the recovery of CR stoves.
In a preferred embodiment, in the step of copper concentrate to be carried out to melting in smelting furnace, after cooling
Make in copper ashes input smelting furnace and melting processing is carried out together with copper concentrate.Copper ashes is made by adding after cooling, can be alleviated molten
Problems of excessive heat during refining, can make fusion process be easier to carry out under higher oxygen-rich concentration, and therefore reduce generation
Exhaust gas volumn.
In addition, the smelting temperature preferably in fusion process is 1150~1300 DEG C, and the addition of the first flux is institute
State the 1~20% of copper mine gross weight.
It is above-mentioned to make copper reaction to direct output anode copper.In a preferred embodiment, in copper stove is made
The step of copper reacts is made in the progress of one copper matte regulus also to be included：While adding cold burden in copper stove to making, and/or water is sprayed into making in copper stove
Mist, and/or cooling element is set outside the body of heater for making copper stove；Wherein cold burden includes copper scap, adopting electrolysis residual pole copper and In Crystal Solid Copper
One or more in sulfonium.
To shorten flow, CN103382528 proposes a kind of two steps copper metallurgy technique, and the technique is first in smelting furnace by copper essence
Ore deposit is smelted into the matte of cupric 65~78%, and redox reaction is then carried out in converting furnace directly produces anode copper.The party
Method is primarily present thermal balance question, and the smoke problem brought by it：Redox reaction in converting furnace releases big calorimetric,
These heat must be taken away to maintain thermal balance by certain mode；The technique is passed through by adjusting the amount of oxygen, air, nitrogen
Gas takes away reaction heat, therefore the gas gross sprayed into must be more, and relative oxygen concentration is necessarily relatively low, and this allows for flue gas
Amount is very big, and sulfur dioxide in flue gas content is very low.Therefore, follow-up smoke processing system and acid making system scale is big, investment is big,
Operating cost is high.Meanwhile, penetrating it is large-minded, also result in that the agitation of whole melt is more violent, the kinetic energy that melt washes away furnace lining is big,
The stove longevity is short.In addition, the patent is nor of how make the discard slag with copper in smelting furnace reach 65~78%.
From unlike the thermal balance mode in above-mentioned patent, being employed in the present invention to making and cold burden being added in copper stove, and/
Or water smoke is sprayed into copper stove to making, and/or outside the body of heater for making copper stove set cooling element thermal balance mode.Each mode
Advantage is as follows：
Mode for adding cold burden：It is exothermic reaction due to making the reaction occurred in copper stove, adds cold burden and be conducive to reality
Existing thermal balance, while using liberated heat fusing cold burden is reacted, making full use of heat.The cold burden of addition can be copper scap,
One or more in adopting electrolysis residual pole copper and solid-state copper matte regulus.In current copper metallurgy factory, all using the fusing of single metallurgical furnace, refining
The secondary copper materials such as copper scap, adopting electrolysis residual pole copper, this not only needs extra fuel to heat cold burden, it is often more important that need purchase
Single equipment is put, single workshop is built, configures single workman, factory's operating cost is considerably increased.And use this hair
Bright above-mentioned embodiment, in the case where additionally not increasing equipment, factory building, personnel, has not only handled copper scap, adopting electrolysis residual pole copper
Deng material, the energy, the resource of melting materialss needs are also saved, economic benefit is very notable.In a word, the affluence for making copper stove is utilized
Heat melts composition brass, reduces the processing cost of composition brass, and this method is just agreeing with national Ministry of Industry and Information's non-ferrous metal " 13 " development
The developing direction proposed in planning to the processing of composition brass.
Mode for setting body of heater cooling element：It is preferred to use water jacket, this realizes that body of heater heat is flat also for radiating
Weighing apparatus.
Mode for spraying into water smoke：Because water absorbs big calorimetric in gasification, therefore can be less in final tolerance
In the case of take away more heats, making to make copper reaction can be carried out under the conditions of high oxygen-enriched air converting, and high oxygen-rich concentration blows just
Solve in the patents such as CN103382528 using above mentioned problem caused by the blowing of low oxygen-rich concentration.In addition, spray into water smoke also just like
Lower advantage：1) furnace temperature is more effectively controlled.Because the gasification of water can absorb big calorimetric, spraying into the small change of water can draw
The large change of heat is played, therefore, it is possible to more accurately and effectively control furnace temperature；2) service life of lance is extended.Due to high oxygen-enriched air converting
Efficiency high, spray gun spray into tolerance than low oxygen-rich concentration blow it is few, the working strength of spray gun is low, and the cooling effect of water
The life-span of spray gun in itself can also be extended；3) by taking 40% oxygen-rich concentration as an example, its smelting intensity can be than low oxygen-rich concentration
(21%~25%) it is high nearly 1 times.In the case of exhaust gas volumn identical, the inventory that high oxygen-rich concentration (such as 40%) can be handled
It is high nearly 1 times；4) energy consumption is low, and power consumption is low.The unit scale that the power ratio of Water spraying device blasts air is much smaller.
Just because of the above-mentioned thermal balance mode of the present invention so that making copper stove and can be blown in high oxygen-rich concentration in the present invention
Under conditions of carry out.In a preferred embodiment, carry out making in the step of copper reacts, oxygen-enriched sky is sprayed into copper stove is made
Gas carries out oxidation processes to the first copper matte regulus, make copper reaction, and in oxygen-enriched air oxygen percent by volume for 30~
80%.Although CN103382528 mentions converting furnace oxygen concentration 9~60%, because it is to take away heat, actual oxygen by gas
Concentration can be only sustained at less than 25%, it is impossible to really realize high oxygen-rich concentration.And above-mentioned thermal balance means are relied in the present invention, it is complete
30~80% oxygen-enriched air concentration all can enough be reached.
In a preferred embodiment, make in the step of copper reacts, after the step of carrying out oxidation processes, obtain
Metallic copper and make copper ashes；When make in the metallic copper in copper stove it is oxygen-containing be less than 0.2wt% when, will make copper ashes discharge make copper stove, obtain
Anode copper；When make in the metallic copper in copper stove it is oxygen-containing be higher than 0.2wt% when, copper ashes discharge will be made and made after copper stove, to making in copper stove
Reducing agent is passed through to carry out reduction reaction to the Cu oxide impurity in metallic copper, and then obtains anode copper.
