DECOMPOSITION OF FLOTATION PROCESS - PRECONDITION FOR MATHEMATICAL MODELING

Within Kosova's flotation plants, but also in many flotation's in the region, process control is realized based on empiric data. Creation of one mathematical model, with which can be determined quantitative and qualitative values of flows, is the main goal of this paper. Flotation process that is realized in the heterogeneous, dispersive and multiphase medium and by nature is fully dynamic. This causes that the steady - state parameters are different from prior parameters. With decomposition of technological scheme, based on case study of "Trepca" flotation plant is formed mathematical model of flotation process of lead section. Created model have universal nature and can be applied in similar processes. Special part of model, the constraints of metal flows in the waste outflows from contours, should be defined with experiments in laboratory, processing lab or in the process (using EVOP method).
