  • 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.

  • The Adsorption of Cu Species onto Pyrite Surface and Its .

    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.

  • Selection of lead-zinc flotation circuit design by .

    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.
