The flotation
Froth flotation is a technique that enables solids to be separated from others by using the differences in their surface properties (hydrophobicity >< hydrophilic) when put in the presence of air in a stirred tank. The material, pulped after wet grinding to less than 250 µm, is conditioned through the addition of a chemical reagent called a collector, whose role is to selectively make the floating mineral surface hydrophobic.
CTP has a range of equipment from laboratory to pilot scale for batch on continuous operation.
Equipment | Volume | Operation | Solid flow |
---|---|---|---|
Laboratory cells | 1-8 L | Batch | - |
Mini-pilot cells | 10-40 L | Batch/continuous | 10-100 kg/h |
Mini-pilot flotation bank | 22 x 10 L | Continuous | 10-100 kg/h |
Pilot flotation bank | 2 x 710 L | Continuous | 500-1000 kg/h |
Pilot flotation column | 12.5 L | Continuous | 300 kg/h |
