Process analysis of Pb and Zn during producing iron nuggets by iron bearing dust

摘要

Using the secondary iron bearing dust as raw material, to make high basicity and coal mixed briquette, and then the briquettes are rapid self-reduced to produce iron nuggets at high temperature, at the same time of obtain more pure iron nuggets, the removal rate of alkali metal elements Pb is above 90%, Zn is about removed completely, so as to solve the problem of the damage of alkali metal elements, and this can make great contributions to the energy conservation and emission reduction, and environment protection.
