にして溶錬を行っている。The smelting method of a metal sulfide ore disclosed in this publication is mainly intended to reduce the amount of exhaust gas with respect to the same treatment amount of the metal sulfide ore, and in order to achieve this object, the smelting is performed as follows. It is carried out.

ついては溶錬時一定にしている。That is, in the method of smelting the molten material in the furnace with powdery or granular metal sulfide ore and a solvent as main components together with fuel air (oxygen-enriched air) through a plurality of lance pipes, The temperature of the melt and the quality of the melt are controlled by changing the oxygen concentration of the fuel air and the total blown air volume by keeping the amount of oil of the auxiliary fuel burner used auxiliary during smelting at all or constant, and controlling this. A part of the plurality of lance pipes is separated from the system, and the blowing amount through the separated lance pipes is constant during smelting.

が難しくなる。"SUMMARY OF THE INVENTION" However, proceeds ore increase processing sulfide metal ores, if the generated oxygen in the oxygen plant is used the total amount, that is, when not afford O 2, the oxygen concentration and the total air volume By changing it, it becomes difficult to control the solution temperature and Kawa quality.

い場合には、上述の方法では無理が生じる。Therefore, when it is desired to use the entire amount of generated O 2 , the above method requires changing the O 2 concentration by increasing or decreasing the supply amount of the metal sulfide ore. If the supply cannot be reduced due to the budget, and if it is desired to use the entire amount of O 2 generated, the above method would be unreasonable.

になる。Further, in the above-mentioned method, it is possible to control the solution temperature and the quality of the Kawa with no oil burner or a constant amount of burning, but when the complete burner-free operation (no oil burner is used) is continued for a long time. Therefore, when the total amount of O 2 generated from the oxygen plant is used and the amount of ore supplied is maintained on a budget, it is actually difficult to control the temperature of the solution in order to obtain a predetermined quality of Kawa. Further, if the temperature of the solution is prioritized, it becomes difficult to control the quality of the Kawa.

計送風量の変化によるコントロールを示す。In this invention, the quality of the river and the temperature of the solution are controlled by increasing and decreasing the blowing amount of the pulverized coal and oxygen-enriched air for the heat control. It is shown in Table 1 of the page. As shown in this table, it is effective to increase the blowing amount of pulverized coal without changing the blowing amount of air, especially when the quality of the river is high and the solution temperature is low. That is, when the amount of pulverized coal blown in is increased, the O 2 in the air is burned into the pulverized coal, the temperature of the solution rises, oxidation of the river is suppressed, and as a result, the quality of the river deteriorates. By the way, the lower part of Table 1 shows the control according to changes in the oxygen concentration and the total air flow disclosed in Japanese Patent Publication No. 59-41494.

せることができる。[Advantages of the Invention] As described above, according to the present invention, while the total amount of oxygen generated in the oxygen factory is used and the amount of ore supplied is also constant, and while the burner operation is continued for a long period of time, pulverized coal and air can be increased or decreased. With this, it is possible to simultaneously and freely control the quality of the kawa and the temperature of the solution, and it is possible to reduce the loss of oxygen.

して沈降するので、カラミ中の銅損失は少ない。Further, since the melted raw material is melted by its own reaction heat, the heat transfer to the solution is improved compared to the generally used burner heating method, and moreover, the solution is sufficiently agitated, so that the ability to dissolve the raw material is improved. At the same time, the contact between the river and the kelami is sufficiently achieved by stirring. Therefore, the Kawa particles suspended in the solution are easily coarsened and settled, so that the copper loss in Karami is small.

For the same reason, the temperature of the furnace atmosphere (gas zone in the furnace) can be lowered below the solution temperature,
It also has the effect of improving the life of the lance pipe and reducing the radiation heat from the furnace.
