Abstract (en)
[origin: WO2014133447A1] Iron and niobium containing agglomerates and a process for producing the agglomerates are disclosed. Green agglomerates are produced from a mixture of an iron containing powder, a niobium oxide powder, and a carbonaceous powder. In a preferred embodiment sodium carbonate is added to the agglomerates. The green agglomerates can be reduced at a temperature in the range of 1000-1500 °C.
