Industrial Plant Flotation Machines in Banks

The process depends on the rapid flotation of talc in this rougher flotation stage followed by three stages of cleaning of the rougher talc concentrate. The talc rougher tail and three-stage cleaner tails are all directed to the No. 1 rougher scavenger bank which in this configuration becomes No. 1 copper rougher bank. The cleaned talc concentrate is discarded to final tail. Flotation

An Overview of Optimizing Strategies for Flotation Banks

A flotation bank is a serial arrangement of cells. How to optimally operate a bank remains a challenge. This article reviews three reported strategies: air profiling, mass-pull (froth velocity) profiling and Peak Air Recovery (PAR) profiling. These are all ways of manipulating the recovery profile down a bank, which may be the property being exploited.

Froth flotation - Wikipedia

The rougher pulp [2] passes to a bank of scavenger cells where additional reagents may be added. The scavenger cell froth [3] is usually returned to the rougher cells for additional treatment, but in some cases may be sent to special cleaner cells. The scavenger pulp is usually barren enough to be discarded as tails. More complex flotation circuits have several sets of cleaner and re-cleaner ...

Most flotation circuits include an initial stage of rougher flotation, followed by a scavenger stage of flotation. The objective of passing through the rougher and scavenger flotation circuits is to maximise recovery of the desired minerals into relatively low grade concentrates that may typically contain 5-15 weight percent of the ore feed, (directly related to ore grade).
