spiral concentrators in mineral processing

A simple process control model for T spiral concentrators

The control of spiral concentrators, to provide a concentrate with as little as possible fluctuation in grade and recovery while feed parameters are fluctuating, is difficult and has not been perfected. Large mineral processing plants consist of hundreds of spiral concen-trators, and the adjustment of splitters is time

Spiral (Concentrators) - an overview | ScienceDirect Topics

In the spiral concentrator the length of the sluicing surface required to bring about segregation of light from heavy minerals is compressed into a smaller floor space by taking a curved trough and forming into a spiral about a vertical axis. The slurry is fed into the trough at the top of the spiral and allowed to flow down under gravity.
