Froth Flotation Process

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.

Flotation has been widely used in the beneficiation industry and the flowchart of the flotation experiments (Fig. 1 c). It is most suitable for separating disseminated ores with low grade and fine particles [26]. Graphite has good natural floatability and hydrophobicity. Basically, all graphite can be purified by flotation [27].

Selective flotation of fine-grained pentlandite from low …

Nickel is mainly sourced from laterite and sulphide ores, with 70% sourced from laterite and 30% found in sulphide ores (Farrokhpay & Filippov, 2016). Pentlandite (Fe,Ni) 9 S 8, the major nickel hosting sulphide mineral, is typically processed by froth flotation (Marape & Vermaak, 2012). Pentlandite generally occurs with different sulphide ...

Flotation Froth

The froth flotation technique was originally developed in about 1910 to raise the copper concentrations of the strip-mined ores of Bingham Canyon, near Salt Lake City [9], and was further perfected for the differential separation of lead, zinc, and iron sulfides at Trail, B.C., at about the same time [10].
