Flotation Simulation Modelling Software to Improve Grade ...

24.11.2016  In this video EMC Supasim flotation simulation program is used to simulate the performance of a copper lead zinc plant in southern Spain. Flotation kinetics of key streams are generated by conducting bench scale rate tests on either a laboratory prepared sample of mill feed or grab samples of pulp taken from the plant. And this type of rate test is known as a hot float. A grab sample may or may not be representative and if not, the flotation kinetics

Simulation of flotation plants - Metso Outotec

16.06.2017  The flotation plant flowsheet simulation models provide an efficient way to assess existing circuit operation, further optimize its operating conditions and to evaluate different circuit reconfigurations. When planning a new flotation plant design, simulation models can be used to design the circuit configuration and cell sizing. In both cases the models are based on experimental data from the minerals flotation

01.11.2020  The flotation simulator considers the sequential calculation of each single cell in series, assuming a two-zone system: collection and froth (Finch and Dobby, 1990, Yianatos et al., 2008b). This allows the simulator to evaluate different cells size and arrangement in a flotation circuit. The feed minerals are characterised in terms of size-by-liberation classes.
