Kumera Steam Dryer For Copper Concentrate Kumera

Kumera Steam Dryer For Copper Concentrate Kumera

Through Kumera Steam Dryer, a copper smelter can reduce the harmful emissions such as CO 2, SO 2, NOx and dust. Drying is necessary in many smelting technologies for example, all flash smelting processes of copper and nickel production. Kumera Steam Dryer is widely used all over the world due to its lowest opex compared to any other concentrates drying facility.

A System For The Energy Effective Concentrate Feed Into

Consistent output material. The flash dryer is ultimately energy-effective as the feed material is in the range of 10–20 moisture, whereas the spray dryer requires a minimum of 30 moisture. The spray dryer is efficient as the inlet temperatures on operation are in the range of 900–1 000 C whereas the flash dryer is generally.

The Copper Flash Cc Smelting Process :: Total Materia Article

Chemically, concentrates smelted in flash furnaces contain 20-30 mass Cu, 25-35 Fe and 25-35 S. The process takes place in a flash smelting furnace, which schematically is presented in Figure 1. Main feedstock of the process is a dry Cu-Fe-S concentrate. Very roughly speaking, dry concentrate is blasted with O 2 in the reaction shaft. The furnace is equipped with hydrocarbon fuel burners located.
