Acid curing and agglomeration for heap leaching
2017.1.1 Introduction. Acid curing and agglomeration are generally used prior to heap leaching of copper oxide and secondary sulfide ores to improve the copper extraction process. Agglomeration is used to bind fine particles to coarse ones to increases the permeability of an ore heap while acid curing inhibits the dissolution of some silicates and ...
