In-situ leaching itself is not a new technology. It has been used for Uranium mining for over 50 years and today nearly half of all Uranium mining is done by this method.
FEECO provides custom agglomeration drums (agglomerators) and material handling equipment for the heap leaching component of the SX-EW process. How SX-EW Works. Solvent extraction electrowinning is a complex process of chemical reactions, but can be simplified into three main steps: Heap Leaching Copper Ore with Agglomeration
Heap leaching is the most important method of hydrometallurgical copper extraction. Heap leaching is used for treating oxide and lower-grade secondary sulfide ores that contain up to ∼2% Cu. The ore is crushed to a uniform particle size (typically 12–50 mm), often agglomerated, and then stacked on large flat-topped heaps in a controlled manner.. Heaps are typically ∼7 m high …
