A cascaded recognition method for copper rougher flotation

A cascaded recognition method for copper rougher flotation

Jan 16, 2018 Fig. 1 shows the rougher flotation in a certain copper flotation site. During the whole flotation process, rougher is the first step of screening after ore is ground, mixed with water and classified. The products from rougher include the rougher froth on top of the cell and the pulp flow at the bottom of the cell.

Precise Air Flow Measurement Improves Flotation Cell

Precise Air Flow Measurement Improves Flotation Cell

Flotation cells require precise control of compressed air because the frothing process efficiency is based on the speed of the froth as it moves from the surface of the slurry to the recovery area. The speed of the froth is controlled by the air bubbles induced into the flotation cell, tank level and reagent dosages.

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.
