硼泥部分替代膨润土的探索性研究

Boron mud is the residue in the pyrogenic process producing borax or boric acid with the raw material of szaibelyite or ludwigite in chemical factories，which utilization is relatively low and pollute the environment. Exploratory study on boron mud partly substitute bentonite was carried out in the paper at laboratory conditions. The effects of boron mud on performance of green and roasting pellet were investigated systemically and theoretically. The results showed that boron mud could partly substitute bentonite to oxidized pellet production. The bentonite ratio can be reduced from 1.0% to 0.3% with pulsing 1.0% boron mud additives. In the case, the metallurgical properties of the finished pellets can meet the blast furnace smelting requirements.
