FROTH FLOTATION : RECENT TRENDS Flotation of

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

Flotation – HYTS

Flotation is also used for the removal of interfering impurities before hydrometallurgical treatment, for upgrading of low sulfide and refractory ores for further treatment. Flotation is considered to be the most cost-effective method for concentrating gold. Flotation process maximizes the enrichment of gold into sulfide minerals

Sulfide Ores - an overview | ScienceDirect Topics

Copper sulfide ores must be concentrated before they can be economically transported and smelted. The universal technique for this concentration is froth flotation of finely ground ore. Froth flotation entails attaching fine Cu-sulfide mineral particles to bubbles and floating them out of a water–ore

Jan 01, 1991 These are: (l) selective flotation of copper sulphide ores. This process consists of micro-bubble deposition on the valuable mineral in the presence of both a collector and a frother, followed by particle capture through coalescence with larger bubbles in the pulp which transport the mineral into the froth

Froth floatation process is used for the sulphide ores. In this method, wetting of the ore by an oil takes place. A strong current of air is blown through the suspension, producing a heavy froth or foam on the surface. The metal sulphide is wetted by the oil but the gangues is not and the sulphide-oil mixture is carried to the surface by films of oil The froth is skimmed off, the gangue
