Abstract:
The copper industry generates substantial waste streams and residues containing valuable base metals that represent both environmental concerns and untapped resources. This review examines contemporary hydrometallurgical approaches for selective metal recovery from copper waste solutions utilizing carbonate-bearing technogenic materials. The integration of carbonate precipitation with other separation techniques offers promising alternatives to traditional treatment methods, providing improved environmental performance and economic viability. This literature analysis meticulously reviews publications focusing on leaching mechanisms, precipitation kinetics, selective separation strategies, and process optimization. Key findings indicate that pH-controlled carbonate precipitation achieves metal removal efficiencies ranging from 85-99% under optimized conditions, with mechanically activated calcium carbonate and ammonium carbonate solutions showing particular promise. The circular economy aspects of technogenic waste valorization, coupled with reduced operational costs and lower environmental impact compared to conventional methods, make these approaches increasingly attractive for industrial implementation. Future research priorities include process intensification, selective recovery of multiple metals, and integration with electrochemical recovery techniques.
