Columbite A Mining Process

niobium processing History, Ores, Mining, Extraction ...

Columbite concentrates and tin slags with a high tantalum content (greater than 10 percent) are directly dressed in most cases by a wet chemical process. Low-tantalum tin slags, on the other hand, are first melted in an electric-arc furnace with the addition of a flux material, and the tantalum-niobium content is collected as a ferroalloy .
