The study is based on technical results conducted from October 2015 to January 2016 . Plant physical performance was measured and Metallurgical data was collected. Phase disengagement time in the E1 Mixer was measured S1 were also wi th the mixer operating in organic operating in organic continuous mode. continuous mode; E2 a nd Visual organic in aqueous entrainment appeared to be high in the E1 and E2 aqueous launders. Organic bed depths are at lower levels in the settlers. Crud levels in extractions settlers were high and a d ispersion band was observed in settlers . this led to the reconfiguration of the solvent extraction circuit to minimize the loss of the organic phase. As a result, Boss Mining would like to achieve an annual output of 100,000 tons of cathodes, so a mathemat ical model based on a multi objective approach is proposed Keywords: Optimization; Multiobjective; Integer pro gramming; Goal.
