Unfortunately, the conventional flotation cell achieves high recovery only in limited size ranges. For example, a sulfide ore might float very well at 90 to 120 microns, but not at 50 or 150 microns. The research to date has identified two main reasons for the upper limit on floatable particle sizes.

Froth flotation is a physicochemical separation technique that exploits the difference in the surface wettability of mineral particles (Wills and Finch, 2016).From a heterogeneous mixture of solids, hydrophobic particles are made to attach to gas bubbles and subsequently carried to the froth phase and recovered as a froth product (typically …
The flotation machine must perform a series of complicated functions. Some of the more obvious are: 1. Good mixing of pulp. To be effective, a flotation machine should maintain all particles uniformly in suspension within the pulp, including those of relatively high density and/or size.

The newest releases are engineered to help miners achieve production, safety, and ESG goals. By Jesse Morton, Technical Writer. The leading suppliers in the flotation space are releasing new solutions that they say help a plant improve recovery and throughput while using less energy, manpower and chemicals.
Both large ore particles (larger than 0.1mm) and small ore particles (less than 0.006mm) affect flotation efficiency and mineral recovery. In the case of flotation coarse particles, due to the heavyweight, it is not easy to suspend in the flotation machine, and the chance of collision with the bubbles is reduced.
The pressure for saving water by closing the water loops in mineral processing is increasing continuously. The drivers for higher recirculating rates include water scarcity in dry areas, environmental legislation that is becoming stricter in most countries, limitations set for wet tailings management and the increased demands for …
