Modelling all facets of a processing plant with a vast number of straightforward rules and deterministic equations is highly challenging as the available data is often incomplete and fuzzy Rintala et al 2012 Rintala et al 2015 Instead the target of this study is to develop a software system that is able to give starting points for gold ore process design by helping the
