Flotation Kinetics: Mass & Water Recovery VS Entrainment

Flotation kinetics is also a numerical description of the ore's liberation characteristics of both mineral and gangue. The fast floating fraction is a proportion of feed material that is 80% liberated with 80% free surface area or better; this applies to metal mineral and gangue.

Copper processing Ores Britannica

In the ore-dressing plant, the material received from the mine is crushed in several stages and finely ground to a size which ensures that copper minerals are liberated from the waste materials, or gangue. In cases where the next step is leaching (most frequently in the case of oxide ores), complete liberation of the copper minerals is not always necessary; the ore needs to be crushed and ground only to the .

The mine produces a magnetic waste stream from a low-intensity magnetic separator which has been found to contain approximately 20%WO3. Quantitative mineralogical analyses of this stream have shown that the tungsten is mostly contained within ferberite (FeWO4) which is well liberated from hematite, the main gangue mineral in the magnetic stream.

Minerals that were once thought of as gangue, and were dumped, may later find a commercial use. When this happens, the old dumps are often reworked to extract the wanted mineral. For example, in copper mines in the 19th century the mineral arsenopyrite was dumped until arsenic became popular as an insecticide later in the century.
