2016-06-06  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. The authors suggest that using reactor–separator cells, with more ...
