Extractive Metallurgy of Tantalum: Mineral Processing and …
Abstract. This paper presents a brief review of extractive metallurgy of tantalum starting from processing of its ore to two pure intermediates K 2 TaF 7 and Ta 2 O 5 and their conversion to pure tantalum metal by various technically feasible processes. Though tantalum metal can be produced by several means only two processes – sodium reduction of K 2 TaF 7 …

tantalum-niobium content is collected in the resulting ferroalloy and the tan talum-niobium free slag is poured off. After crushing and dressing, this ferroalloy is converted to a tantalum-niobium concentrate either by means of a second py rometallurgical process, or by means of a chemical process, such as:
