The study envisaged the flotation process to emulsion flotation with fuel oil dosage, and agglomerated flotation with MIBC dosage occurred predominantly with an increase in fuel oil dosage. A new emulsified collector called ZFC (a blend of 27% diesel oil, 70% water, and 3% homemade surfactant) was developed for the flotation of difficult-to ...

"Advanced process control and statistical process control will allow us to do a much better job of controlling the flotation process than we do today," he said. "I have yet to see a mineral processing operation that uses statistical process control; it's difficult to apply to continuous processes. But mines can use it, and they should.
