Tantalum mining technique –blasting, crushing

Tantalum is produced as a byproduct by the tin industry from smelting cassiterite ore concentrates for processing. The biggest tantalum mine is the Mibra mine in Nazareno, Brazil. The Extraction and refining of tantalum is done by treating the ores with a mixture of hydrofluoric and sulfuric acids at elevated temperatures, because of which

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 .
