Flotation Process - an overview | ScienceDirect Topics

The most interesting part of the flotation curves is the increase in recovery of molybdenum with ultrasonic power, as shown in Figure 35.29. The increase in recovery of iron is not good news for copper mines because the more iron floating the lower grade of recovery. This may be because the iron becomes more hydrophobic with ultrasonic action. According to the experts, this situation could be ...

Flotation behaviour of gold associated in the plati-num group metals is apparently the same as that for the PGMs or other minerals associated with the PGMs (i.e. nickel, pyrrhotite, copper and pyrite). Therefore, the reagent scheme developed for PGMs also recovers gold. Normally, for the Sotation of PGMs and associated gold, a combination of xan-thate and dithiophosphateis used ...

DESIGN AND PERFORMANCE ASPECTS OF COAL FLOTATION ...

Flotation is commonly used to treat fine coal (typically below 500 microns in size) and is a complex, three-phase process that is controlled by factors which can be divided into three facets: coal, chemistry and machine. It is most often used for treating metallurgical coal fines where the value of the product can justify the added treatment cost of cleaning and dewatering the product ...

Dissolved Air Flotation in Industrial Wastewater Treatment

Dissolved air flotation (DAF) is a process for removing suspended particles from liquid by bringing particles to the surface of the liquid. The influent feed liquid can be raw water, wastewater or liquid sludge. The flotation system consists of four major components: air supply, pressurizing pump, saturator (retention tank), and flotation chamber. According to Henry's law, the solubility of ...

Optimizing Flotation Circuit Recovery by Effective Stage ...

the flotation circuit configuration is not very se nsitive to stage recovery [9,19 ]. The overall output suggests that choosing the best flotation circuit is not sensitive to the stage recovery, and as a result, only approximate values of the recovery can be used to select the optimal flotation circuit [6,9,20 ].
