When jets of air are forced up through the bath, the water repellent copper mineral particles are picked up by the bubbles of foam. They float to the surface making a froth. The unwanted waste rock (gangue) falls to the bottom and is removed

Unlocking Minerals from Ore – The Value of Froth Flotation. Froth flotation is an important concentration process that selectively separates hydrophobic valuable minerals from hydrophilic waste gangue. In its simplest form, froth flotation is a method where minerals can be “skimmed” from the surface of “slurry” that is “foamed” with the assistance of specific chemicals, water

Aug 21, 2020 · Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of copper. The ores typically contain low percentages of copper and have to be concentrated before refining (e.g., via froth flotation).

In the flotation process of the copper mine, the use of flotation reagents to change the surface properties of the mineral is a flexible and effective way to control the flotation behavior. It is also an important reason why flotation can be widely used in mineral processing. This article mainly focuses on copper collectors, inhibitors, activators, foaming agents, ore-leaching bacteria, lixivium, extractants, etc
