A procedure for the benefit of a type that contains iron oxide material

摘要

Method for Increasing the content of iron oxide type materials. A mixture formed by partculas material and carbon particles, you will add a gas containing chlorine, to form a fluidized bed at a temperature between 800 and 1100 C, which cloran certain amounts of iron content in the material, forming hierr chloride Or.The effluent gas of fluidized bed is in contact with a controlled amount of Oxygen to oxidize the ferrous chloride content in the Effluent and forming a mixture of Iron chloride and FERRIC oxide. Condenses this iron chloride and is separated from the effluent back to volatilize, put him back into contact with oxygen and oxidizing FERRIC oxide.The Chlorine released in stages in the form of gas is recycled back to the fluidized bed.
