  • FROTH FLOTATION : RECENT TRENDS Flotation of Sulphide

    History of Sulphide ore flotation dates back to beginning of 20th century. Sulphide ores are major sources of base metals like Copper, Lead, Zinc, Nickel, Cobalt etc. Beneficiation of these base metal sulphide minerals is predominating through froth flotation technique. This technology has acclaimed importance as a versatile process for

  • Effect of pH on the Recovery and Grade of Base Metal

    B. Froth Flotation Flotation is a physio-chemical process which exploits the differences in the electrochemical properties of mineral surfaces. All minerals are soluble in water to some extent, which results in the formation of an ‘electrical double layer’ at the mineral surface. Flotation depends directly on the

  • Projects — Missouri Cobalt

    Froth flotation is particularly effective in recovering cobalt, nickel and copper minerals from above ground ore stocks and underground ores. The MMPP is designed to handle 300-360 tons per day of feed and can produce 1000-1500 tons per month of salable concentrate.

  • The selective flotation of pentlandite from a nickel ore

    Jun 01, 1995· Bulk flotation An efficient procedure for nickel recovery is to combine copper sulphate to activate pentlandite with guar gum to depress talc. This is the method which has been used for the flotation of nickel ores in industry and which we have termed the "standard bulk float". A selection of results for this ore is given in Table 3.
