beneficiation methods and routes (Bergmann et al., 2016; Tripathy et al., 2013). Even if the mineral to be enriched is the same, to beneficiate the ores obtained from different regions, the corresponding distinctive process flowsheets should be studied. In other words, the design of the beneficiation routes should be ore based.
