Abstract

The present invention discloses a continuous copper smelting method and a device with the integration of float smelting and immersion air refining. The front part of the device is a float smelting section, low pressure rich oxygen air with small power consumption is adopted to vertically or horizontally spray copper concentrate into the space of the device and to be in the float state, and the deprivation of iron and sulphur in the copper concentrate is mainly completed in the section, to produce high quality copper matte regulus; the rear part of the device is an immersion air refining section, rich oxygen air with high pressure is blown into the liquid of the copper matte regulus molten mass in a side blowing or top blowing way, and a small amount of residual iron and sulphur in the copper matte regulus are deprived continuously, to obtain metallic copper.

Description

Floating smelting and immersed air refining integrated continuous copper smelting method and device thereof
Technical field
The present invention relates to the Non-ferrous Metallurgy field, especially a kind of integrated less energy-consumption continual copper smelting technology that the spatial chemical reaction forms with occurring in 2 processes of chemical reaction in the melt that occurs in.
Background technology
Traditional pyrometallurgical metallurgy is branch melting and two stages of blowing, and must carry out in 2 independent device.Smelting apparatus output copper matte regulus, copper matte regulus send the blowing device again, the output metallic copper.At present, main in the world copper smelter has reverberatory furnace, electric furnace, blast furnace, flash stove, molten bath stove etc.; The blowing device has PS converter, flash stove, molten bath stove etc.Because the melt of smelting furnace output need be transported with crane, or delivers to converting furnace after the broken curing of water, there are long flow path, energy consumption height, invest shortcomings such as big; Particularly, cause the leakage pollution of S02 also because process is discontinuous.
Since the sixties in 20th century, world's metallurgy of copper bound pair continual copper smelting has been done many researchs, but all be the reaction process that is confined to immersion, promptly at first copper ore concentrates is melted, in the liquid of melt, blast the bigger high-pressure oxygen-enriched air of power consumption then, under submerged state, finish all processes of melting and blowing.For example fertile carat (Worcra), Rouyn-Noranda (Noranda), Mitsubishi (Mitsubishi), Ao Simaite technologies such as (Ausmelt).So far, realize industrialized only Mitsubishi process, but it remains branch melting and two stages of blowing, and carry out in 2 independent device, just the copper matte regulus of smelting furnace output is directly to send into converting furnace through chute, has avoided the crane transportation.
The characteristics of immersed air refining are to send into oxygen-rich air in the liquid of melt, need higher pressure of blast (about 200Kpa), and therefore, power consumption is greatly the common drawback of various whole process immersion continual copper smeltings.
Summary of the invention
The object of the present invention is to provide the integrated apparatus of the mutually integrated continual copper smelting method of 2 processes of a kind of floating smelting and immersed air refining and it, be intended to energy-conservationly, avoid the S02 leakage pollution and reduce construction investment.
Technical scheme of the present invention is: a kind of floating smelting and immersed air refining integrated continuous copper smelting method, this floating smelting and immersed air refining integrated continuous copper smelting method are the continual copper smelting methods of a kind of integrated floating smelting and 2 processes of immersed air refining; At first, the space of the vertical or horizontal jetting device of powdery copper ore concentrates and oxygen-rich air, and under afloat, finish fusion process, and generate copper matte regulus, be deposited in the molten bath.Then, in the liquid of copper matte regulus melt, continue to blast oxygen-rich air with side-blown or top blast mode, copper matte regulus is blown into this device of metallic copper to be made up of the floating smelting district of fore portion and the immersed air refining district of rear section, be provided with partition wall between the immersed air refining district of floating smelting district and rear section, partition wall is a half-section, and the partition wall bottom is provided with lets out the copper hole.Also be provided with the eye of wind in the immersed air refining district.
Device is made up of the floating smelting district of fore portion and the immersed air refining district of rear section, and the vertical or level of copper ore concentrates and oxygen-rich air sprays into the smelting zone, and afloat with concentrate in most iron and sulphur remove, generate the higher-grade copper matte regulus; In the blowing district, in the liquid of copper matte regulus melt, blast oxygen-rich air with side-blown or top blast mode, a small amount of remaining iron and sulphur are continued to remove, and obtain metallic copper.
Floating smelting and 2 processes of immersed air refining are combined in the device carry out, and iron and removing of sulphur mainly are to finish in the floating smelting district in the copper ore concentrates.Because it is floating smelting only needs lower pressure of blast (about 20Kpa), therefore energy-conservation.
The invention has the advantages that: copper is smelted realized short flow process and serialization, and in incorporate closed unit, finish.Particularly since in the copper ore concentrates iron and removing of sulphur mainly be to finish in the lower floating smelting district of power consumption, the heat in smelting zone and blowing district balance mutually simultaneously, thus energy-conservation, avoid SO2 to leak, invest low.

Embodiment
A kind of floating smelting and immersed air refining integrated continuous copper smelting method, this floating smelting and immersed air refining integrated continuous copper smelting method are the continual copper smelting methods of a kind of integrated floating smelting and 2 processes of immersed air refining; At first, the space of the vertical or horizontal jetting device of powdery copper ore concentrates and oxygen-rich air, and under afloat, finish fusion process, and generate copper matte regulus, be deposited in the molten bath.Then, in the liquid of copper matte regulus melt, continue to blast oxygen-rich air with side-blown or top blast mode, copper matte regulus is blown into this device of metallic copper to be made up of the floating smelting district of fore portion and the immersed air refining district of rear section, be provided with partition wall 3 between the immersed air refining district 2 of floating smelting district 1 and rear section, partition wall 3 is a half-section, and partition wall 3 bottoms are provided with lets out copper hole 5.Also 2 be provided with the eye of wind 4 in the immersed air refining district.
Device is made up of the floating smelting district 1 of fore portion and the immersed air refining district 2 of rear section, and the vertical or level of copper ore concentrates and oxygen-rich air sprays into the smelting zone, and afloat with concentrate in most iron and sulphur remove, generate the higher-grade copper matte regulus; In the blowing district, in the liquid of copper matte regulus melt, blast oxygen-rich air with side-blown or top blast mode, a small amount of remaining iron and sulphur are continued to remove, and obtain metallic copper.
Floating smelting and 2 processes of immersed air refining are combined in the device carry out, and iron and removing of sulphur mainly are to finish in floating smelting district 1 in the copper ore concentrates.Because it is floating smelting only needs lower pressure of blast (about 20Kpa), therefore energy-conservation.
