SELECTION OF MECHANICAL FLOTATION EQUIPMENT

Mechanical flotation cells can be broken down into two broad categories based on how air is introduced to the cell. In a self aspirated flotation cell air is introduced to the slurry, the vacuum created by the rotorusing . In a forced air flotation cell air is generated external to the cell by a low pressure blower,, and pumped down the

Flotation-assisted electrodeposition process to recover copper …

Then, the flotation machine was inflated and the froth products were continuously collected for 5 min. The float collections (non-metallic tailing) and sunken fractions in the flotation cell (metal-rich concentrate) were respectively filtered and dried at 75℃ for 120 min. For each grade, the flotation parameters are shown in Table 1.

Dual-chamber flotation machines are not new. Early forms of the modern dual-chamber pneumatic cells can be traced back to the early 1960s [].Their primary characteristic is that—unlike mechanical flotation cells where the gas-particle adhesion occurs in an agitated, aerated tank—most of the gas-particle adhesion takes place in a separate, high-intensity …
