Die Biohydrometallurgie als Teilgebiet der Hydrometallurgie macht sich spezielle Stoffwechselleistungen von Mikroorganismen zur Metallgewinnung zu nutze. Biomining ist die angewandte Biolaugung zur Metallgewinnung aus sulfidischen Erzen. Für das Recycling, also die Metallgewinnung aus Abfall und Reststoffen, gibt es bisher noch keine angewandten biohydrometallurgischen Verfahren, aber vielversprechende Laborversuche zur Metallextraktion aus Feststoffen. In diesem Übersichtsartikel werden diese zusammenfassend dargestellt und Perspektiven aufgezeigt.

“…On the other hand, when the sulfidogenic unit is in direct contact with the metallurgical stream, the circuit is called in-line (Figure 1.6B). The choice of circuit configuration depends on the water chemistry 112 , as each configuration has its own advantages and disadvantages.…”

“…Biosulphide ® , by BQE, is an off-line sulfidogenic process initially demonstrated as a SO 4 2-reduction system at the Britannia Copper Mine, Canada 72 ; but recent reports claim it now produces H 2 S from S 0 reduction for the removal of transition metals 92 . Similarly, Paques B.V. offers two sulfidogenic systems, SULFATEQ and THIOTEQ, for SO 4 2contaminated stream treatment and metal recovery, respectively 112 . These technologies share the commonality of being based on neutrophilic sulfidogenic microorganisms 112 , and as a result, the available technologies are compartmentalized and carry the same economic and operational constraints as discussed before.…”

The development of an extremophilic process could overcome the limitations of an in-line system (Figure 1.6B) and expand the sulfidogenic technology for metal recovery to a wider range of industrial applications.…”

Thermoacidophilic elemental sulfur reduction for the recovery of metals from hydrometallurgical streams

General introduction | 13 presenting a grievous future, while the baseline and moderate scenarios offer a sobering but more promising outlook. However, the milder scenarios are contingent on increasing material recycling and optimizing metal recovery rates. This chapter focuses on the recovery of metals through hydrometallurgical operations, aiming to provide a general understanding of these processes and identifying opportunities for improving the metal recovery process, with a specific focus on sulfur reduction for metal recovery, the state-of-the-art, and current limitations. The metal recovery process and the tailing problematicThree metallurgical processes are used in the extractive metallurgy process: a. Pyrometallurgy is a method of extracting metals from their ores by using high temperatures, typically in a furnace, to release the metal 29 . The metal can then be recovered from the solid residue or the gases produced during the process. The main steps of pyrometallurgy include drying, briquetting, roasting, smelting, and refining 16 .SRB to grow in a large variety of electron donors and aerotolerant characteristics makes SRB ubiquitous in the environment, even in conditions where SO 4 2is depleted 102 . Elemental sulfur (S 0 ) reductionThe second dissimilatory microbial sulfur metabolism microorganisms use to obtain energy is the reduction of S 0 . In the S 0 reduction metabolism, two electrons are consumed for the reduction of S 0 into H 2 S (eq. 1.7), a four-fold reduction in the electron donor consumption compared to SO 4 2-. In this metabolic pathway, no activation energy
