Can bottom-blown furnaces for copper smelting achieve continuous feeding and the production of coarse copper?
Thread Content
Currently, there are several companies in China that carry out bottom-blown copper smelting, but they have not achieved true continuous feeding or a method for removing crude copper. I would like to ask the experts: how can continuous feeding and continuous discharge of crude copper be achieved?
Generally, the blast furnace is used to feed crude copper into the anode furnace, with refining in the anode furnace taking place in stages.
Can the flue gas concentration and flow rate in the blowing furnace be kept stable?
As far as we know, it is stable at present
The operation of the anode furnace is intermittent; is it necessary for the smelting furnace to operate continuously when processing crude copper?
We need to continuously feed copper and keep the material supply steady, in order to achieve a balance in the bottom-blown furnace
This is very difficult; no one can do it at the moment
In bottom-blown furnace melting, from the processing of lead to that of copper, the oxidation stage and the reduction stage are carried out separately, and it is not possible to achieve continuous production in the overall process. An idealized continuous feeding, slag removal, and product extraction is not yet possible, nor is it necessary.
What if the feed and furnace operating conditions are stable?
What kind of balance is it? Level? Thermal energy? Atmosphere? Or something else.
