Prospective directions for biohydrometallurgy

Hydrometallurgy, 2020
Abstract Biohydrometallurgy has been commercially applied for the extraction of base metals from low-grade sulfidic ores and the pre-treatment of refractory sulfidic gold-containing minerals. Recent research explores its potential for other types of commodities, such as rare earth elements, and ores found in deep subsurface of the Earth, ocean floor ...

Economic and environmental niches of biohydrometallurgy

Minerals Engineering, 1996
Abstract Numerous processes co-exist for metal extraction and for metal removal from effluents of mining operations. Each process enjoys an economic advantage, including environmental cost and benefit, if utilized in a specific situation. This applies equally to biohydrometallurgical processes.

Importance of the iron cycle in biohydrometallurgy

Hydrometallurgy, 2006
After the discovery in the 1940s that acid mine drainage was mainly a consequence of the metabolism of chemolithoautotrophic microorganisms able to oxidize metal sulfides, mostly pyrite, much research has been performed to understand the ecology and the physiology of the microorganisms involved.

Biohydrometallurgy: What is its Future?

Advanced Materials Research, 2009
Bioleaching/minerals biooxidation and bioremediation have been widely used commercially for heap/dump bioleaching of secondary copper sulfide ores, sulfidic-refractory gold concentrates and treatment of acid rock drainage. Technical and commercial challenges, identified in this paper, remain for bioleaching of primary sulfides and complex ores.
