Flotation is the process of separation of beneficial minerals from a mixture by creating froth on which minerals separate out. This is a method of mineral processing in which different minerals are separated selectively. The ores containing multiple metals, such as lead, copper and zinc, can be selectively extracted by using froth floatation.

The sorting process is stable and easy to control, the allowable range of feed concentration is wide, the enrichment ratio is high and the recovery rate is high. Advantages It is widely used in the treatment of tungsten, tin, gold, platinum, iron and some rare metal ores, especially in the treatment of low-grade sand ores.
Hotspots specific to flotation have been identified and should be used to orient data gathering when focusing on this process. Five options of functional unit and …
Froth flotation is a physicochemical process that is used to separate fine mineral particles from aqueous suspensions by selective attachment of some types of minerals to air bubbles. Froth flotation is the most important mineral processing technology for the production of valuable mineral concentrates from which metals and minerals are …
Wolframite mineral processing method mainly in gravity separation, and includes four parts: pre-selection, gravity separation, concentration and recovery. By pre-selection and discarding the waste rock which accounts for 50% of the raw ore, the WO3 grade of the ore is enriched from 0.25% ~ 0.3% to 0.45% ~ 0.8 %, and the recovery is …
In this study, the flotation tests revealed that ethylenediamine tetramethylenephosphonic acid (EDTMPA) as a calcite inhibitor has a stronger depression effect than EDTA (ethylene diamine tetraacetic acid) in the cassiterite flotation process, and the selective depression mechanism of EDTMPA was revealed by zeta potential …
The increased demand of metals such as tantalum (Ta) and niobium (Nb) reflect the on-going development in modern science, engineering and technology. The extraction of these two metals from columbite-tantalite ore is based on generic extractive metallurgy. However, the upstream purification of ore and downstream extraction of Ta …
The flotation method refers to the beneficiation process of floating solid minerals from the suspension (pulp) of water according to the differences in physical and chemical properties of mineral surface [26]. Flotation has been widely used in the beneficiation industry and the flowchart of the flotation experiments (Fig. 1 c).
