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 it generates will not be a true reflection of the streams floatation characteristics.
- If this happens and you cannot repeat the test, what do you do?
- How to use flotation kinetics to determine what is required to improve plant recovery?
What you see here is a flow sheet for the copper lead zinc plant where you have the copper circuits on your left, the zinc circuit on your right; both have reground mills. It looks very congested that is because it’s got a lot of options. These are valves where you can operate the circuit, in open circuit or in close circuit. And there’s a lead upgrade here. You produce copper concentrate ….Read more
