摘要
Bauxite from Qingzhen is calcined for refractories :tpplications. Three fuel sources with different amounts of residual ash and ferric oxide were used for bauxite calei- 'zation in a rotary kiln. It is found the quality, inclu- ling the content of ferric oxide, bulk density, apparent porosity and water absorption, of the bauxite is highly itfluenced by the fitel source of rotary kiln. In essence, the effect of fuel on the quality of bauxite is attributed to !he amount of ferric oxide introduced by the fitel. Intro- duction of a modest quantity of ferric oxide is beneficial for promoting the densification of bauxite.
