Hydro metallurgy of Nickeliferous - Froth Flotation

If nickel in your “3% nickeliferous ore” is present as a sulphide mineral typically pentlandite , you should be able to get a 20% Ni concentrate dependant on how much other stuff is in there – Cu, Fe, MgO, etc. using standard froth flotation: pH 9.0 – 9.5 PAX MIBC

Froth flotation - Wikipedia

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste-water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Froth flotation - Suntech Geomet

Literature: Flotation is the most versatile mineral processing technique that has made it possible to mine most low grade and complex ore bodies that would have been regarded as uneconomic. Though complex and not completely understood, flotation has been used to achieve specific separations from complex ores like Pb-Zn-Cu, Pb-Zn and Cu-Zn etc. Initially developed for sulphide ores, flotation has

Frothers - an overview ScienceDirect Topics

The most widely accepted method for upgrading ultrafine coal is froth flotation. Froth flotation is a physicochemical process that separates particles based on differences in surface wettability. Flotation takes place by passing finely dispersed air bubbles through an aqueous suspension of particles Fig. 17 . A chemical reagent, called a frother, is normally added to promote the formation of small bubbles.

Flotation Reagent - an overview ScienceDirect Topics

Flotation Reagent. Flotation reagents have two important structural features: a functional group consisting of donor atoms or ligands, and a substituent group, which is hydrophobic consisting of alkyl aryl hydrocarbon chains in the case of collectors and frothers, or hydrophilic in the case of modifiers except for inorganic modifiers, which comprise mainly inorganic bases and metal ions .
