A flotation cell is a vital piece of equipment used in the mineral processing industry to separate valuable minerals from waste material through the process of froth flotation. It operates by introducing air bubbles into a slurry, allowing hydrophobic particles to attach to the bubbles and rise to the surface, where they can be collected as a froth concentrate. This process plays a …

By introducing air bubbles, flotation cells allow minerals to attach to the bubbles and rise to the surface, where they can be collected as concentrate, while unwanted materials sink as tailings. Widely used in mining, flotation cells enhance mineral recovery and purity, making them essential for processing ores like copper, lead, and zinc.
