Abstract

The whole or part of the iron, manganese, and tin which is contained in materials containing tantalum and/or niobium prior to the treatment for the recovery of the tantalum and/or niobium, is eliminated by treating the materials with a gaseous mixture of hydrogen and chlorine, the respective amounts of the two gases being such that there is substantially more than one molecule of hydrogen for each molecule of chlorine and preferably from 5 to 10 times the volume of the chlorine. Specification 474,604 is referred to.
