Copper ore Heap leaching abstract It is known that the presence of excess ﬁnes in heap leaching operations may cause low recovery due to reduced heap permeability and/or channeling of lixiviant ﬂow. These problems are mitigated to some extent by agglomeration pretreatment prior to heap leaching. Sulfuric acid leach solution is the conven-

agglomeration.2.1 Crushing Copper ore from the mine is reduced in size to about half inch top size by crushing. A detailed explanation of the agglomeration process is provided in Chapter 3. About 66% of copper mines that crush the ore perform agglomeration [18. 1. 1. 18].33]. copper ore is agglomerated prior to heap leaching [18 .2.
