Bjӧrkdal Gold Mine''s mill discharge circuit poses various challenges, due to it consisting of an interactive collection of sumps that feed the gravity separation circuit. For optimal gravity circuit performance, the hydrocyclones and spirals require a constant feed flowrate. An MPC strategy was implemented to balance the volume between four mill discharge tanks in order to attain a constant gravity feed flowrate.
