OUTOTEC FLOTATION SKIMAIR FLASH FLOTATION UNIT

In conventional flash flotation, a SkimAir cell is operated as a standalone cell in a single stage process. The single stage process can be recovery or grade driven. In a two stage process, the SkimAir is used as a rougher unit to produce a lower grade concentrate at high recovery, and an Outotec TankCell174 is used as a cleaner to

Flotation Machines Mineral Processing amp Metallurgy

Currently, flotation cell design is primarily a proprietary material of the various cell manufacturers. Flotation plants are built in multiple cell configurations (called banks), and the flow through the various banks is adjusted in order to optimize plant recovery of the valuable as well as the grade of the total recovered mass from flotation.

Jameson cell

The high intensity of the Jameson Cell means that it is much shorter than conventional column flotation cells (see Figure 1), and it does not require air compressors to aerate the suspension of ground ore particles and water (known as a slurry or pulp) in the flotation cell. The lack of a requirement for compressed air and the lack of moving parts means that power consumption is less than for

The future of flotation CIM

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.
