hydrometallurgy of tantalum

Tantalum mining technique –blasting, crushing, transporting

Tantalum mineral concentrates may restrain from 2 to more than 5 dissimilar tantalum-bearing minerals from the similar mining area. The trade of tantalum mineral concentrates is dependent on a certified examination for the tantalum oxide they enclose, with an assortment from 10 or 15 to over 60% based on the mine source.

Dosage, Agitation, Filtration, Processing Hydrometallurgy

Hydrometallurgy is opposed to pyrometallurgy which is the process that separates metals by using different melting temperatures. Hydrometallurgy is composed of three major steps : Leaching : dissolution of the ore in acid; Purification of impurities, mainly on heavy metals, by electrochemical reduction or carburization; Selective separation of ...

Hydrometallurgy - an overview | ScienceDirect Topics

Hydrometallurgy refers to the application of aqueous solutions for metal recovery from ores, and has been practiced for copper recovery for many years. The original impetus for solution methods for copper extraction before the development of froth flotation technology was the existence of large ore bodies of low copper content which were uneconomic to work using conventional smelting methods.
