Froth flotation is an important concentration process. This process can be used to separate any two different particles and operated by the surface chemistry of the particles. In flotation, bubbles are introduced into a pulp and the bubbles rise through the pulp. In the process, hydrophobic particles become bound to the surface of the bubbles.

WhatsApp: +86 18203695377Flotation is a physiochemical process that utilises particles' physical attachment to bubbles to separate minerals by floating them to the surface of flotation cells. Hydrophobic (or water repelling) surfaces can attach to bubbles and be floated, whereas hydrophilic (or water attracting) surfaces cannot.

WhatsApp: +86 18203695377Froth flotation. Froth flotation uses a chemical collector and frother that forms bubbles on the surface of the slurry that hydrophobic materials bind to. The bubbles are collected off the surface of the frother. Activators are used to enable the flotation of one mineral ore while depressants are used to inhibit the flotation of the gangue.
WhatsApp: +86 18203695377Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and wastewater treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.
