Abstract
The invention provides a method for producing raw copper from matte converting water quenching slag by adopting reverberatory smelting. The method comprises the following steps: carrying out water quenching on top-blown furnace matte converting slag containing 14-22% of copper and 32-48% of iron, then adding the slag into a reverberatory, adding 1-3% of matte converting slag and reducing coal of which the particle size is 1-20mm, and carrying out reduction smelting at the temperature of 1200-1250 DEG C so as to obtain raw copper in which the copper content is greater than or equal to 95% and reverberatory slag in which the copper content is less than 2%. By adopting the method provided by the invention, the direct recovery rate of copper is greater than 90%. The converting slag after water quenching does not need to be specially prepared and only needs to be blended with a right amount of reducing agent to be smelted in the reverberatory, so that the material preparation is simple.
Description
Technical field
The present invention relates to copper smelting-furnace residues processing technique, be specifically related to the treatment process method of pushing up the blowing slag that Bessemer blow matte produces.
Background technology
During Copper making is produced, the blowing refinement of the matte becomes that the technique of blister copper has PS to bessemerize, Flash Smelting Furnace blowing, top Bessemer blow etc., due to technological process difference, the blowing slag properties that different converting methods produces also difference to some extent.PS converter and Flash Smelting Furnace, owing to can control certain reducing atmosphere in stove, and have the sedimentation molten bath of geo-stationary, and the slag Armco magnetic iron content that blowing produces is lower, and Copper in Slag is also lower, general cupric 3% ~ 10%; And push up Bessemer blow, because stove internal oxidition atmosphere is strong, and be subject to the stirring of spray gun, can not form the sedimentation molten bath of geo-stationary, the slag Armco magnetic iron content of generation of thus blowing is higher, and Copper in Slag is also higher, general cupric 14% ~ 22%, iron content 32% ~ 48%, wherein copper mainly exists with metallic copper, cupric oxide and cupric sulfide form, and iron is mainly with Armco magnetic iron (Fe
3o
4) form existence.For the top blast stove the blowing refinement of the matte slag of cupric 14% ~ 22%, generally take the method with copper ore concentrates mixed smelting, contained copper weld pool is become matte, and then blows, produce blister copper.This treatment process, makes a large amount of copper and iron form circulation on stream, and not only energy consumption raises, and production efficiency is lower, and the integrated smelting rate of recovery also can be caused to reduce.
Summary of the invention
The object of the invention is the deficiency that top blast stove the blowing refinement of the matte slag higher for cupric and copper ore concentrates mixed smelting produce by solution prior art, a kind of the blowing refinement of the matte water granulated slag is provided to adopt reverberatory smelting to produce the method for blister copper, to improve the direct recovery rate of copper.
Object of the present invention is achieved through the following technical solutions:
A kind of the blowing refinement of the matte water granulated slag adopts reverberatory smelting to produce the method for blister copper, the top Bessemer blow matte slag of cupric 14% ~ 22%, iron content 32% ~ 48% is added reverberatory furnace after shrend, and add the reduction coal of blowing matte slag 1 ~ 3%, granularity 1 ~ 20mm, at 1200 DEG C ~ 1250 DEG C temperature, carry out retailoring, obtain the blister copper of cupric >=95% and the reflection slag of cupric < 2%.
The present invention joins in reverberatory furnace and carries out retailoring after allocating the blowing refinement of the matte water granulated slag into appropriate reductive agent, obtains the reflection slag that the blister copper of cupric 95% ~ 99% and cupric are less than 2%.The direct recovery rate of copper is greater than 90%.Blowing slag after shrend does not need special preparation, and only need allocate appropriate reductive agent into just can enter stove melting, and material preparation is simple.
