Crushed ore agglomeration and its control for heap leach

网页2013年2月1日Crushed ore agglomeration has two major aims. First, it is the best opportunity for the thorough application of the leaching solution prior to building the heap and “kick starting” the leaching process itself ( Bouffard, 2005, Dhawan et al., 2012a, Kodali et al., 2011a, Purkiss and Anthony, 2004 ).
