Flotation Material Balancing Excel Solver: Mass Balance …

For a flotation circuit, material balance calculations define an engineering problem where flow parameters between unit operations are partly known. The purpose of a material balancing is to mathematically examine the known flow parameters to solve for the unknown flow parameters. Two main types of material balances are commonly made: design material balance operating plant material …

Modelling for froth flotation control: A review

 · Most of the existing phenomenological models are based on the kinetics of the flotation process, assuming well-mixing conditions or plug flow, and have been used to represent both the pulp and froth phases. While kinetic descriptions provide good approximations for pulp phase behaviour, they are not adequate to model froth phase behaviour.
