Froth flotation is the follow on operation after comminution and classification in the process of liberating and separating minerals by exploiting the differences in physical properties of the different minerals that make up an ore Froth flotation is achieved when particles are separated based on their surface potential. If you are interested in our company's products, we welcome your consultation 7/24 hours, and we are committed to creating the most suitable solution for you.
Sep 29 2020 Froth flotation is a process using air bubbles to separate materials based on their relative affinity to water Bubbles carry reagent and hydrophobic materials to the top of a tank where they can be removed Froth flotation has been used for more than a century in mining operations to separate valuable materials from excavated ores.
Optimizing Flotation Cells H ow a flotation cell works Flotation Cells Froth Flotation were developed to separate and recover high value Sulphide ores from low grade ore bodies The ore is crushed and milled at the concentrator in a process known as comminution where the mineral is in suspension in slurry.
