Bioleaching of Electronic Waste: Milestones and Challenges

Jan 01, 2017This review examines the status of bioleaching technology in recovering valuable metals from electronic waste (e-waste). Bioleaching of e-waste is reviewed with emphasis on the mechanisms of leaching, the diverse organisms that have been used, and the factors that have affected their performance, including the bacteriostatic effects of the leaching

Two advances in e-waste recycling: use of fruit peal waste

Aug 26, 2020Bioleaching requires very little energy and so has a small carbon footprint. No toxic chemicals are used either, making it environmentally friendly and safe. Despite how useful it is, applying bioleaching to e-waste has mostly been an academic pursuit. But our research group is leading the first industrial effort.

Bioleaching Wikipedia

Bioleaching of non-sulfidic ores such as pitchblende also uses ferric iron as an oxidant (e.g., UO 2 + 2 Fe 3+ ==> UO 2 2+ + 2 Fe 2+). In this case, the sole purpose of the bacterial step is the regeneration of Fe 3+. Sulfidic iron ores can be added to
