Hydrometallurgical Approach for Leaching of Metals from ...
Pyrometallurgical metal production results in side streams, such as dusts and slags, which are carriers of metals, though commonly containing lower metal concentrations compared to the main process stream. In order to improve the circular economy of metals, selective leaching of copper from an intermediate raw material originating from primary base metal production plant was investigated.
Copper: Automation, Isolation Controls | Bray
Copper leaching concentrate plants play a crucial role in copper production. Both vat and heap leaching plants utilize acids to leach, collect, and concentrate the valuable copper leached from the ore. Copper extracted by heap leaching is percolated through the pile and collected as pregnant leaching solution, in a concentrates pools for downstream processing. Vat leaching works in a similar ...
