It also provides a premier interdisciplinary platform for researchers, practitioners and ...
Copper heap leaching with agglomeration. Heap leaching relies on a leaching agent moving through a bed of heaped ore to extract the metallic components: Crushed ore is stacked on a leaching pad and irrigated with the leaching agent.
Our approach to heap leach engineering follows the traditional custom of initially defining project criteria, and then focusing on the most efficient manner to develop conceptual and ultimately detailed engineering design drawings, specifications and quality assurance programs that meet the project criteria. Project criteria typically include:
