Preparation and performance study of filter media made by blast furnace dust for a biological aerated filter;

The height change of foam caused by reduction gas during foaming process was measured under different conditions of treating blast furnace dust in iron bath.

The results showed: Mixing 1% blast furnace dust can reduce sinter solid burning-out 4.

BF gas mud contains a lot of iron.

Research on zinc and bismuth recovery from blast furnace sludge;

The FeCl_2 solution was synthesized by using flue slime of blast furnace as raw materials on gas and solvent extraction.

By analyzing and researching utilization of BF dust,a technology of dealing with the BF gas slime adopting the containing carbon pellet direct roasting reduction method was put forward.

Based on the analysis and research on the use of blast furnace dust at home and abroad and in combination with properties,features and present situation of the BF gas slime at Meishan,a new idea about recovering iron concentrate from BF gas slime with low high intense magnetic separation is put forward.

The process of dealing with the BF gas slime adopting roasting reduction method with Rotary Hearth Furnace was studied.
