Nickel Laterite Ores Floatation

Jun 06, 2016 Flotation has not been successful in recovering nickel from laterite ores, as the nickel is often finely disseminated in various minerals at a very fine size. Ultrafine grinding has to be used to liberate nickel-containing particles, but the resultant fine particles means that recovery is low in conventional flotation cells.

    Jun 10, 2016 It should be added that segregation of laterite ores prior the flotation process has shown some improvement in upgrading nickel. The segregation process relies on the addition of calcium chloride or sodium chloride and carbon allowing the formation of nickel and iron chlorides at temperatures between 900 and 1150 C.Iwasaki et al., 1961 and Nagano et al., 1970 have reported nickel ...
