Lithium recovery from lithium-containing micas using sulfur oxidizing microorganisms

Autor: T. Aubel, Eberhard Janneck, Mirko Martin, Susan Reichel, A. Patzig

Publikováno v: Minerals Engineering. 106:18-21

There is about 60,000 t of lithium mica in the German part of the deposit in the Erzgebirge mountains. Lithium can be recovered by high pressure-high temperature leaching with sulfuric acid and further hydrometallurgical processing. Another idea, dev

The potential of granulated schwertmannite adsorbents to remove oxyanions (SeO32−, SeO42−, MoO42−, PO43−, Sb(OH)6−) from contaminated water

Autor: Stefan Peiffer, Jacqueline Engel, Susan Reichel, Eberhard Janneck, Bouchra Marouane, Maria Klug, Karel As

Publikováno v: Journal of Geochemical Exploration. 223:106708

The mineral schwertmannite forms in acidic sulfate-rich environments (pH 2.9–4) and has a large sorption potential for oxyanions. In this study, we tested the properties of granulated schwertmannite produced from material obtained from a mine water

Treatment of opencast lignite mining induced acid mine drainage (AMD) using a rotating microfiltration system

Autor: Tim Aubel, Eberhard Janneck, Katja Meschke, Volker Herdegen, Jens-Uwe Repke

Publikováno v: Journal of Environmental Chemical Engineering. 3:2848-2856

Acid mine drainage (AMD), specifically from opencast lignite mining, contains large quantities of dissolved iron, can be strongly acidic, and may emerge in high volume flows. In addition, AMD can contain heavy metals and toxic elements in high concen

Metal Recovery and Exploitation of Lignite Ashes by Combined Physicochemical and Biotechnological Approaches

Autor: Beate Brett, Susan Reichel, René Kermer, Franz Glombitza, Axel Schippers, Sabrina Hedrich, Daniel Schrader, Petra Schönherr, Eberhard Janneck, Konstantin Räuchle

Publikováno v: Advanced Materials Research. 1130:296-299

Ashes from lignite combustion for power generation contain strategic metals, metalloids and rare earth elements and may thus be a potential source of industrially demanded metals. The presented project focuses on the assessment and exploitation of th

Recovery of indium from sphalerite ore and flotation tailings by bioleaching and subsequent precipitation processes

Autor: Mirko Martin, Susan Reichel, Anke Patzig, René Kermer, Eberhard Janneck

Publikováno v: Minerals Engineering. 75:94-99

Flotation tailings dump material of the former lead–zinc mine near Freiberg (Germany) consists of fine grained quartz, feldspar, mica as well as the sulphide minerals pyrite, galena and sphalerite not recovered by flotation. Sphalerite contains, as

Bench-scale study of the effect of phosphate on an aerobic iron oxidation plant for mine water treatment

Autor: Judith S. Tischler, Eberhard Janneck, Claudia Wiacek, Michael Schlömann

Publikováno v: Water Research. 48:345-353

At the opencast pit Nochten acidic iron- and sulfate-rich mine waters are treated biotechnologically in a mine-water treatment plant by microbial iron oxidation. Due to the low phosphate concentration in such waters the treatment plant was simulated
