Several steps are involved in the extraction of tantalum from tantalite. First, the mineral is crushed and concentrated by gravity separation. This is generally carried out near the mine site. The refining of tantalum from its ores is one of the more demanding separation processes in industrial metallurgy. The chief problem is that tantalum ores con… WebJun 2, 2024 · Liquid–liquid extraction is the most effective way of separating tantalum and niobium, both metals are extracted and separated from acidic leach liquors by using organic extractants such as methyl iso-butyl ketone (MIBK), tri-butyl phosphate (TBP), cyclohexanone and 2-octanol. 13 Alternative extractants have been also investigated, …
