Challenges In Processing Nickel Laterite Ores By Flotation
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.

Laterite nickel deposit is formed by the weathering and leaching of nickel-bearing peridotite in tropical or subtropical regions. As a nickel ore, it was discovered by Garnier in New Caledonia in 1863, so the ore is called “garnierite”—a magnesium-based nickel silicate. Because the ore is red due to the
