Bioleaching technology
Bioleaching technology is a process that utilizes microorganisms to extract valuable metals from ores and other mineral resources. It involves the use of bacteria or fungi to break down the mineral matrix and release metals through biochemical reactions. This environmentally friendly method reduces the need for harsh chemicals and energy-intensive processes traditionally used in mining.
In addition to conventional metal recovery, bioleaching has gained increasing attention for the extraction of rare earth elements (REEs) from industrial sludge and waste residues. Traditional extraction technologies often yield relatively low purity levels (typically below 60%) due to complex mineral matrices and inefficient separation processes. In contrast, microbial-assisted extraction can significantly enhance recovery efficiency and purity by selectively solubilizing target elements through metabolic activity and organic acid production.
Overall, bioleaching technology offers a sustainable, efficient, and selective approach to metal and rare earth element recovery, with promising applications in waste valorization, circular economy strategies, and environmentally responsible resource management.
