Froth Flotation
Froth flotation is a selective separation process to separate valuable materials (recyclables, minerals, and other fine-size waste) from unwanted materials (gangue) using air bubbles in a general floatation tank, Jameson flotation cell, or flotation column. From: Recycling and Reusing of Engineering Materials, 2022.

Flotation Froth
The gangue-rich underflow from the rougher cells is passed through a series of scavenger cells to collect any residual copper sulfide values not picked up by the rougher cells. Dried flotation concentrates contain from 20 to 30% copper (frequently 25–28%). The concentration process recovers 80–90% of the metal content of the ore feed.

At Silver Queen mine (Canada) a combined lime-starch-SO 2 conditioning scheme is used for copper flotation from the Pb/Zn sulphides (Bulatovic, 2007b). In the process, lime (1200 g/t) and starch (200 g/t) are used first, at pH 10.5–11.2, after which the pH is reduced to 5.5 with SO 2 (200 g/t) and the copper sulphide floated.
