Processing Nickel Ores

Most nickel ores have several recoverable metals in them and the process if commonly a multiple stream of metals recovered. The copper concentrate is sent to the copper smelter and 99.99% copper cathode is produced in electrowinning cells. The nickel ore is sent to the nickel refinery, where a complex set of reactions is carried out.

Nov 16, 2016On the other hand, the HPAL process is used more commonly for limonitic ores with high iron, containing low magnesium and silica. The process starts with crushing, followed by screening. In this step, it is commonly evaluated if the ore can be concentrated (beneficiated) by screening, where the enriched-silica fraction is separated from the ore.

(PDF) The Past and the Future of Nickel Laterites

Tropical weathering (laterization) comprises a prolonged process of mechanical and chemical weathering that produces profiles of great variability in thickness, grade and chemistry and ore mineralogy. Nickel laterites occur in present or past zones of the earth that have experienced prolonged tropical weathering of "ultramafic" rocks containing ferro-magnesian minerals (olivine, pyroxene, and amphibole)
