Crushed ore agglomeration. 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).

2018-7-5 Agglomerate quality. For these reasons, agglomeration can greatly improve ore recovery rates in a heap leaching operation. As has been demonstrated, however, the quality of the agglomerates is critical to maximizing recovery. Many factors influence agglomerate characteristics including drum rpms, ore moisture content, feed rates and retention time.

The volume agglomeration for a node-centred scheme proceeds in the following steps:. 1. build a list of the so-called seed points. Seed points are grid points selected to agglomerate the surrounding control volumes. The list of seed points can contain either those points which form an approximate maximal independent set [75], or simply all points of the current grid level.
