feed enters the flotation cell

Aug 12, 2015 The slurry flow then enters the feed end of the flotation cells. The slurry at this point is called the HEADS of the circuit. The mineral is then separated and flows over the overflow into a trough called a flotation cell LAUNDERER. The OVERFLOW is

Feb 28, 2016 Flotation columns and mechanical cells respond in a similar way to the chemical variables and many of the physical ones. Feed characteristics will have a similar effect on both machines. They also respond to reagents in much the same ways. Air Rate. Apart from changing grade and recovery, gas rate affects the position of the pulp/froth interface itself

The tailings discharge, on conventional flotation machines, is on the opposite end of the cell from the feed, ensuring the slurry travel the entire length of the cell past multiple banks containing impeller-diffusers, before being discharged as tailings.

However, changing conditions can still cause problems, especially in relation to the gravity feed system. A pneumatic flotation cell operates on the principles of mixing the air and pulp in a continuous stream, and ensuring that correctly sized bubbles are fed into the pulp as it enters the cell. This maximizes the number of particle and bubble
