Smelting copper concentrate in closed blast furnace, reverberatory furnace, electric furnace or flash furnace to produce crude copper, and then sending the matte (matte) produced to converter for smelting.

Cooked copper is obtained by putting raw copper into a reverberatory furnace, removing impurities through oxidation refining, or casting it into an anode plate for electrolysis.

2, the impurity content is different

There are many impurities in crude copper.

Cooked copper has less impurities.

3, the performance is different

Raw copper has no elongation, is easily broken, and has poor toughness and compactness.

Mature copper has good elongation, toughness, easy stretching, high thermal and electrical conductivity, strong chemical stability, high tensile strength, easy welding, corrosion resistance, plasticity and ductility.

4. Different uses

Crude copper is used for casting faucets, valves, water meter shells, artistic sculptures and other products.

Mature copper can be drawn into thin copper wire and made into thin copper foil.
