What is Flotation in Oxide Copper Extraction? - Mining-pedia
Amine flotation method, also known as cationic collector flotation method, is a commonly used flotation method for non-ferrous metal oxide ores (copper, lead, zinc). It is used in malachite, azurite and chalcopyrite, etc. Amine collectors are selective for oxide copper, because amines also have a capturing effect on many gangues.

Flotation Reagents & Collectors | ArrMaz
The process involves the aeration of minerals in water in the presence of flotation reagents which facilitate the attachment of air bubbles to and levitation of select minerals. Once at the surface, the select minerals are supported by a froth layer until they are removed. Unattached materials remain submerged in the pulp.
