Additionally, the use of high frother concentration can result in persistent and too stable froth formation, leading to overflow in the flotation cells, pumping problems and handling difficulties in the flotation concentrator (Bournival et al., 2017a, Wei et al., 2014). As a consequence of this significant influence of frothers on the overall ...

The MAC flotation cell is mainly used in the flotation section of waste paper deinking pulping, for removal of hydrophobic impurities such as filler, ash, ink particles, etc. It can increase pulp whiteness and meet the requirements of final paper appearance quality. Table 11.11 shows the features of MAC flotation cell.
Flotation Cells (Froth Flotation) were developed to separate and recover high value Sulphide ores from low grade ore bodies. The ore is crushed and milled at the concentrator in a process known as comminution, where the mineral is in suspension in slurry. The particle size for mineral being recovered is generally less than <0.1mm.
Additionally, a standard range of flotation cell sizes was established to process 100-4500 m 3 /h, with a naming convention that communicates the equivalent conventional flotation capacity delivered by each StackCell model (e.g. SC-100 provides equivalent flotation capacity as a 100-m 3 conventional flotation cell). 1.3.

Two flotation tests were conducted to duplicate the experiment. Zinc sulfate (ZnSO 4) and dextrin (Dextrin Gul) were used in the copper-lead rougher flotation stage to depress sphalerite whereas potassium amyl xanthate (KAX) and triethylene glycol monobutyl ether (Nasfroth 240) were used as a collector and frother reagent, …
All new high-capacity flotation cells are supplied with e-Drive units. Replacing the belt-driven drive units in higher-capacity cells with the eDrive direct-drive gearboxes will improve equipment efficiency, makes maintenance easier, and reduces the overall lifetime costs.
