Name the substance used as depressant in the separation of two sulphide ores in Froth floatation method. Answer Froth floatation method of concentration of sulphide ore. Sulphide ores are preferentially wetted by oils while the gangue is preferentially wetted by water. The ore particles get adsorbed on oil droplets and come to the surface

2020-6-8Laboratory investigations on the possibility for magnetic separation of sulphide minerals are reported. A survey of several sulphide ores and flotation concentrates shows that magnetic separation in most cases is not a suitable primary method of beneficiation. However encouraging results have been obtained in concentrate purification. Traditionally magnetic separation is associated with iron

2011-12-1History 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
