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.

AMIT 145: Lesson 5 Froth Flotation Mining Mill Operator

Flotation Circuits. Flotation circuits are typically comprised of rougher, scavenger and cleaner flotation banks. Rougher and scavenger banks are focused on recovery and thus provide maximum residence time. Rougher banks can be large with the number of cells being 5 or greater. Scavenger cells are the last line of defense for avoiding losses.

Froth flotation Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic.This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
