process of differential flotation

    Model Predictive Control of Mineral Column Flotation Process- process of differential flotation ,This work addresses a model predictive control design for a mineral column flotation process modeled by a set of nonlinear coupled heterodirectional hyperbolic partial differential equations (PDEs) and ordinary differential equations (ODEs,which accounts for the interconnection of well-stirred regions represented by continuous ,US5439115A - Process for selective flotation of copper ,In a process for a selective flotation of a copper-lead-zinc sulfide ore the raw ore is ground and slurried with water and the resulting suspension is aerated with air to adjust a certain oxidation-reduction potential and is subsequently successively conditioned with SO 2 , Ca(OH) 2 , and collecting and frothing agents, whereafter a flotation of Cu is ,.
