Self-aspirated flotation cells are a type of flotation equipment used in mineral processing to separate target metals and minerals from their ores. In self-aspirating flotation, air is introduced into the slurry – a mixture of water and finely ground ore – by vacuum created by the cell rotor.

The flotation process and related flotation cells are widely used for treating metallic and nonmetallic ores and in addition, it is receiving an ever widening application in other industries. A greater tonnage of ore is treated by flotation than by any other single process. Practically all the metallic minerals are being recovered by the flotation process and the …

The present work investigates a comparative study between mechanical and ImhoflotTM cells on a mini-pilot scale and the applicability of one self-aspirated H-16 cell (hybrid ImhoflotTM cell) on an industrial scale on-site. The VM-04 cell (vertical feed to the separator vessel with 400 mm diameter) was fabricated, developed, and examined. The copper flotation …

Prior to compositing the individual downbank rougher and scavenger cell products, for modal analysis, the metal distribution by flotation cell products was determined. It was apparent from this analysis that most of the lead, presumably as liberated galena in the ore, was recovered in the scavenger circuit.
