Description
Technical field
The present invention relates to copper pyrometallurgy field more particularly to a kind of Copper Matte Converting method and apparatus.
Background technique
Global Copper making is quickly grown, and the scarcity of raw material makes smelting enterprise that must not be not suitable for the variation of raw material, main body
Now high miscellaneous raw material proportion is higher and higher in the feed；Meanwhile being full of to the processing capacity of high miscellaneous raw material as cupper smelting
The criterion of benefit.Copper concentrate material composition is increasingly sophisticated and blister copper impurity element is higher and higher, be mainly reflected in Pb, As, Sb,
The content of Bi, Ni increase；Copper pyrometallurgy end product quality is influenced by more serious, cause anode copper quality fluctuation compared with
Greatly, the stabilization of Cathode Copper Quality is influenced.Anode copper mass directly affects the economic skill of items of Cathode Copper Quality and electrowinning process
Art index；Meanwhile a large amount of unqualified anode copper need to melt down processing, and pyro-refining process back mixing processing cost is caused to increase, and
Cause the back mixing loss of the metals such as copper, gold, silver.
The converting process of copper matte regulus is intermittent cycle operation, and whole process can be divided into two ranks of slag-formation period and copper making period
Section.In the first stage of blowing, with the oxygen blasted in air or oxygen-enriched air strong oxidation reaction occurs for the FeS in copper matte regulus,
The FeS in copper matte regulus is oxidized to FeO and SO at this time2.FeO can be with the SiO in flux after adding flux2It reacts and carries out slag making,
Gradually rise copper content in sulfonium.Since copper matte regulus is different from the mutual solubility very little and density of clinker, so stopping in blowing
Melt can be divided into two layers when wind, and upper layer clinker is periodically discharged.The first stage of Copper Matte Converting characterized by a large amount of clinkers of output,
Therefore also known as slag-formation period.In the second stage of blowing, the oxygen and Cu in air are blasted2Strong oxidation reaction occurs for S, generates
Cu2O and SO2, Cu2O again with unoxidized Cu2S reaction generates Ni metal and SO2.The second stage of Copper Matte Converting be added without flux,
Not slag making, characterized by output blister copper, therefore also known as copper making period.
The side-blown converting process of currently used P-S converter (Pierce-Smith converter), can better adapt to raw material
Variation, product quality reach control and require, and with compared with bottom blowing converting furnace, multiple gun top blast converting furnace, side-blown converting furnace has operation
Simply, the advantages such as cold material processing is more, removing impurities ability is strong.But due to the operation mode of its discontinuity operation, a period needs sublevel
Section feeding leads to its frequent grate；Meanwhile the space requirement to consider crane charging, petticoat pipe design cannot achieve effectively close
Envelope；Because P-S is bessemerized, grate is frequent and petticoat pipe leakproofness difference causes low vacancy pollution more serious, is unable to satisfy environmental protection production and wants
It asks.
