The company sells copper tube sheet circle the ribbon wire square and more.
To increase the copper content in the matte, it is subjected to the contractile
the smelting. Melting is carried out in the same shaft kilns. Stein download
pieces the size of 30-100 mm with quartz flux, limestone and
Cox. The coke rate is 7-8% by weight of the mixture. In the
get enriched in copper matte (25-40% Cu) and slag (0,4-0,8% Cu).
Melting point melting concentrates, as already mentioned,
apply a reverberatory and electric furnaces. Sometimes kiln
feature directly above the area of the reflective furnaces with the
not to cool the roasted concentrate and use their heat.
As heating of the charge in the furnace run the following reduction reaction of the oxide of copper and the higher oxides of iron:
6CuO + FeS = 3Cu2O + SO2 + FeO;
FeS + 3Fe3O4 + 5SiO2 = 5(2FeO × SiO2) + SO2
In the reaction of the resulting cuprous oxide Cu2O with FeS is obtained Cu2S:
Cu2O + FeS = Cu2S + FeO
The sulphides of copper and iron, melting between them, constitute the primary
Stein and molten silicates of iron, flowing down over the surface of the slopes,
dissolve other oxides form a slag.
Noble metals (gold and silver) do not dissolve in the slag and almost completely transformed into Stein.
