Frothing, also known as froth flotation, is the process of selectively separating hydrophobic valuable minerals from hydrophilic waste gangue. In its simplest form, froth flotation is a method whereby minerals can be "skimmed" from the surface of "slurry" that is "foamed" with the assistance of specific chemicals, water and air bubbles.
2019-10-11 · flotation technology for the mining and minerals processing industries.

2021-2-17 · Copper flotation process Mining – separating minerals by flotation Measurement made easy — Introduction The flotation process can separate a required mineral such as copper, nickel, molybdenum or zinc from ore. Flotation can separate this mineral from waste materials or from another mineral. The process starts with crushed ore. A ball mill
2021-2-15 · goes on to another separation process or to waste. The ability of a mineral to float depends on certain conditions. One important floatation variable is pH, which affects: − the form of many ionic species present − the charge state of the mineral surfaces − the form of many collectors. Separating Minerals by Floatation Copper processing ...
