To overcome percolation problems, a major improvement was made with the introduction of agglomeration prior to ore placement. If the ore particles and/or agglomerates are of similar size, segregation can be avoided to a great extent (Heinen, 1980, Herkenhoff and Dean, 1987, Kinard and Schweizer, 1987, McClelland et al., …
Prior to mining, all rocks contained in a mineral deposit must be placed in one of several categories known as ore types. Each ore type describes a different way that the rock will behave in processing. The ore type determines which process stream a particular mined unit will be sent to, sets expectations for process engineers and …
