The ...

FLOTATION TECHNOLOGICAL - Martin Vialatte

Batch flotation is based on the same principle as continuous flotation. The difference is that this flotation takes place in a closed circuit. The unclarified must is fined, then passed through the flotation pump and sent into the vat. The sudden release of the pressurised gas causes micro-bubbles to form, bringing the small and medium-sized ...
