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.

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 balance.
Three different flotation models which relate feed grind size to flotation circuit performance were developed in this paper using data collected from an industrial flotation circuit. These models differed in terms of their complexity of derivation and the amount of data required for model calibration.
The mass of each sample was arbitrary but much more than the minimum sample mass determined by Gy's model (Pitard, 1993). Each of the five sets of samples were assayed by ICP and mass-balanced using the BILMAT program. A modified Z-score method (Yu et al., 2004) was used to compare the five sets of mass balance data and to identify outliers ...
