The Two Kinds Of Copper Production Regeneration Methods

At present our production of renewable methods of copper there are two categories: the first is the direct smelting of scrap in the various grades of alloy of copper and copper alloys,silicon powder, refining, is also the direct use of law, the recycling of the copper before the second group treatment methods of fire thrown anode.And then copper electrolytic copper and electrolytic refining in the electrolytic recovery of other elements.Second value approach to waste copper, there are generally three types of processes, namely, a process that the two-step method and the method in three steps.

The duration of the same furnace refining operation, work, low productivity and recovery of metals.   Copper by smelting of copper in a blast furnace and kiln reduction.And convert copper refining in the reflection of anode copper and copper alloys for the first recycled blister.Then refined copper obtained in an oven. Since anode reflection of these two methods to law.Blast called by two processes, ERDU Four Pass will get a higher copper impurities, was black, called black copper.   The fee for the first blast furnace to melt copper reduction in the dark, black bubbles and copper in blister copper converter during the temperate periods blister copper refining furnace,manganese powder, then reflection in the treatment of anode materials copper.Raw go through three processes copper anodes produce qualified method called three-phase phases method.Three better use of raw materials, production of smoke composition is simple, easy to use, simple blister copper refining furnace degree temperature, more equipment and increasing productivity,nickel powder, but more complex processes, equipment and investments and more fuel economy and more benefits. Therefore, China and the Regulation of the membrane of large companies may need special treatment, generally used the technique of copper-processing method and two steps.
