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.

The adsorption of Cu species onto pyrite surface and its effect on flotation were investigated by using microflotation tests, first-principle calculations, and XPS surface analysis. The results indicated that the flotation of pyrite appears to be activated with CuSO4 only at alkaline pH, while being depressed at acidic and neutral pH. The adsorption of copper ions on pyrite surface .

As an example of metals that often occur together in ores can be specified copper, lead, zinc, silver and gold, where lead (Pb) and zinc (Zn) can particularly be highlighted as metals whose minerals usually occur . From the above, it is evident that selection of an adequate Pb-Zn flotation circuit design can be identified as MCDM problem.

In a process for a selective flotation of a copper-lead-zinc sulfide ore the raw ore is ground and slurried with water and the resulting suspension is aerated with air to adjust a certain oxidation-reduction potential and is subsequently successively conditioned with SO 2, Ca(OH) 2, and collecting and frothing agents, whereafter a flotation of Cu is effected.

At Silver Queen mine (Canada) a combined lime-starch-SO 2 conditioning scheme is used for copper flotation from the Pb/Zn sulphides (Bulatovic, 2007b). In the process, lime (1200 g/t) and starch (200 g/t) are used first, at pH 10.5–11.2, after which the pH is reduced to 5.5 with SO 2 (200 g/t) and the copper .
