In the paper the utilization direction of the desulfuration residue is introduced in domestic and foreign,the utilization of the desulfuration residue in domestic is discussed.

This paper focus on the various usage and wide market prospect of desulfuration residue to put forward an environmental protection subject on how to utilize the .

On account of high content of FeO,S,P,Al2O3,MgO in the desulfurized slag,they can be oxidated and give out heat.

Research on preparing potassium compound fertilizer via roasting the mixtrue of potash feldspar with desulfurization ash;

Various comprehensive utilization routes are discussed based on the characters of the desulfurization ash derived from circulating fluidized bed boiler.

In order to meet the request of producing product with lower sulphur and high additional value,hot metal pretreatment is an important step in the process of iron and steel production,especially,the development of hot metal desulphurization and slag skimming is very fast.

An experimental study prepared geopolymer by the FGD residues and fly ashes was done,the compressive strength of the geopolymeric products reach up to 36.
