Abstract
The invention relates to a method to produce blister copper or high grade matte in a smelting reactor directly from a sulfidic copper concentrate containing material and/or finely ground copper matte, whereby oxygen-containing gas, copper concentrate and/or finely ground copper matte are fed into the reactor. According to the invention CaO and SiO2 containing flux is fed into the smelting reactor along with oxygen-containing gas, copper concentrate and/or copper matte, and part of the copper in the concentrate and/or in the matte is oxidized in order to form a slag in which the CaO/SiO2 ratio is higher than 1.5, and in which the copper content is in oxidized form, and in which the lime content calculated in a CaO+SiO2+FeOx=100 system is higher than 20%.
Description
The present invention relates to a kind of at melting reactor, for example in the suspension smelting furnace, the direct pyrometallurgy method of producing blister copper by the matte of the sulfide concentrate of blister copper and/or fine grinding.
Known method of prior art is to adopt several steps by sulfide concentrate raw materials for production copper or blister copper, wherein, concentrate is at the suspension reactor of the air that has air or oxygen enrichment, and for example melting in the suspension smelting furnace obtains to contain the copper of 50-75wt.% and the rich copper matte of slag.This method is at United States Patent (USP) 2,506, done introduction in 557.The matte that forms in the suspension smelting furnace is transformed into blister copper and further refining in anode furnace in for example Pierce-Smith type converter or flash converter.
In the suspension reaction stove, directly produce blister copper at certain final condition economically feasible by sulfide concentrate by a treatment step.The greatest problem that exists during the direct production blister copper comprises that copper is very big with the amount of separating (deportment) and formation slag of slag.A large amount of slags requires further treatment step, so that copper is reclaimed, this can influence the economic feasibility of this method.
If the copper content in the sulfide concentrate is enough high, 37wt.% at least typically, such as in Australian Olympic Dam smelting furnace, copper content then can directly be produced blister copper by a step economically usually above 40wt.% in concentrate there.When using aforementioned concentrate, the slag amount of generation is less, still, for the production sulphur content is lower than the blister copper of 1wt.%, must the selective oxidation condition, the result contains the copper of 15-25wt% in the slag of generation.
If the concentrate that copper content is lower has favourable composition, then also be suitable for the direct production blister copper.For example, in the Glogow of Poland smelting furnace, adopt a step to produce blister copper by concentrate, reason is that iron level is low, and the slag amount of generation is not very big.Adopt common concentrate can cause all slagging of all iron and other gangue by a step production of copper.This method is at United States Patent (USP) 4,030, introduces in 915.
FI (Finland) patent 104838 has been introduced a kind of method of directly being produced blister copper in suspension reactor by copper sulfide concentrate, in this method, adds this concentrate, flux and oxygen-rich air in reactor.The cooling and the matte of fine grinding are sent in the suspension reactor with concentrate,, wherein, sent into that degree of enrichment reaches 50% oxygen at least in the air in the reactor so that absorb heat that concentrate discharges and the relative quantity that reduces slag.
But the method in this FI patent 104838 only limits to following occasion: the enrichment degree of oxygen is higher than 50% oxygen, and the quality of concentrate is limited in containing and is higher than 31% copper.According to the quality of concentrate, this patent only limits to use the silicate slag (basic oxygen-free calcium) of iron and the wustite slag (not containing silicate substantially) of calcium.
PCT patent application WO 00/09772 has introduced the method for melting copper sulfide concentrate, in this method, copper sulfide concentrate is carried out the oxygen melting, and, most of iron in the copper sulfide concentrate removed enter in the slag, and part that will be wherein or most of sulphur are with sulfurous gas SO
2Form remove, thereby obtain white metal, be the copper of white metal matte or blister copper form by sulfide concentrate.According to this method, by in copper sulfide concentrate, adding SiO as flux
2Material and CaO material are implemented the oxygen melting, produce slag and white metal, be white metal matte or blister copper, wherein CaO/ (the SiO in the slag
2+ CaO) weight ratio is 0.3-0.6 (CaO/SiO
2=0.43-1.5), Fe/ (FeO
x+ SiO
2+ CaO) weight ratio is 0.2-0.5.The purpose of PCT patent application WO 00/09772 provides a kind of copper sulfide concentrate melting technology that is used to produce white metal or blister copper, this technology oxidation of sulfureted copper ore concentrates or matte continuously under 1300 ℃ or lower temperature, but the melting complexity that does not have magnetite, this technology are suitable for processing and contain SiO
2, low copper sulfide concentrate or the matte of copper loss in the slag, it can be by the copper that contains in the floatation recovery slag, with arsenic, antimony with plumbously remove the degree height that enters slag, and low to the erosion degree of refractory materials.
But PCT patent application WO 00/09772 is only applicable to following slag compositing range, wherein, and CaO/SiO in the slag
2Ratio be lower than 1.5, and silica content is higher in the slag, at pure CaO-SiO
2-FeO
xIn the system (CaO=18.6%), SiO
2Minimum content is about 12.4%.When lime content in the slag increased, the content of silicon oxide also must increase in the slag, thereby the slag total amount also correspondingly increases.For example, as CaO/ (CaO+SiO
2) ratio be 0.6, and Fe/ (CaO+SiO
2+ FeO
x) ratio be reduced to 0.2 o'clock by 0.5, the amount of slag increases more than the twice.CaO/SiO
2The maximum value of ratio be 1.5.
The objective of the invention is to eliminate the shortcoming of prior art, and, obtain the direct by the matte production blister copper of sulfide concentrate and/or fine grinding or the method for high quality matte, wherein in suspension reactor of a kind of improvement, in order to form slag, also added silicon oxide-containing (SiO simultaneously
2) and the material of lime (CaO), described slag is liquid under 1250-1350 ℃ temperature.Can obviously find out the essential characteristic that the present invention is new by following technical scheme of the present invention.
