The ion flotation process is based on the impartation of ionic metal species in hydrophobic waste water using surface active agents (surfactants) and subsequent removal by air bubbles of these hydrophobic species (Zhu et al., 2020). The scale of the air bubbles in a flotation cell should be sufficient to provide appropriate surface area for ...
The flotation process for the concentration of ores is a method by means of which one or more of the minerals in the ore (usually the valuable ones) are picked up by means of a liquid film and floated at the surface of a mass of fluid pulp. Here they are separated from the other minerals, which remain immersed in the body of the pulp. In …
