Increase uptime and ease the maintenance burden. Separating minerals in a froth flotation cell has a particularly corrosive effect on a slowly rotating rake and its components. Mixtures of slurry, surfactant, water, air and froth can quickly lead to failed seals and bearings. Which, of course, means costly unplanned downtime and lost productivity.
Inspection and maintenance-friendly construction. SelectaFlot flotation combines both primary and secondary flotation in one compact unit, resulting in advantages for inspection and maintenance. In order to save floor space, different configurations and cell arrangements are available, such as double-decker or piggy-back.
The mill speed can be varied man ually from zero to 78 per cent of critical. Though normally run to draw maximum horsepower, it can be slowed for extremely soft ores. These would otherwise overload the flotation and gravity circuits. "We've put screens on the primary mill, instead of the original cyclones," explains Lovering. "This

The IsaMill is a horizontal high speed stirred mill that operates with very high power intensities (up to 350 kW/m3). In comparison, the power intensity of a ball mill is about 20 kW/m3. The high Flotation Cell that generates finer bubbles to process the IsaMill product that has a P80 sizing
Control and Optimisation of a Gold Milling and Flotation
Bjӧrkdal Gold Mine's mill discharge circuit poses various challenges, due to it consisting of an slowly changing the pump speed to avoid sump level limit violations that this disturbance resulted in the pulp level of all the flotation cells deviating drastically from setpoint. As a consequence the final grade and recovery was affected.
Increased liberation and flotation performance of bulk
