| Abstract: | A new process with selecting reduction,melting separation and smelting of Nb Fe alloy is proposed to handel the Baotou ore with low Nb and high Fe contents. The main steps of this process were researched by experiments. The rate of Nb recovery by melting separation step is over 95% and by alloy smelting step over 85%. The total rate of Nb recovery for the process is over 80%. Nb/P in alloy is over 15. With this process,the Nb,Fe and Mn in Baotou ore can be comprehensively recovered. |
