FROTH FLOTATION - National Metallurgical Laboratory
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
Recovery of copper is by standard flotation reagents identified in the copper ore flotation description Molybdenum will float naturally with the copper but can be crowded in the froth by the copper mineralization and use of a moly collector (such as diesel oil, kerosene, refined oils, pine oil or xanthate ester) enhances its floatability
