Abstract
A method for retrofitting process equipment into a flotation cell, wherein the flotation cell comprises a flotation tank (10) comprising a centre (11), a perimeter (12), a bottom (13), and a side wall (14); a launder (2) and a launder lip (21); wherein the method comprises forming a retrofitted flotation cell (1) by installing the process equipment to the flotation cell, wherein the process equipment comprises at least one device for combining an air stream and a slurry infeed (100) to obtain particle-bubble aggregates and then introducing the combined air stream and slurry infeed (100) into the tank (10), and providing a slurry recycling circuit (3) to the retrofitted flotation cell (1) wherein the slurry recycling circuit (3) comprises a pumping system.
