Lateritic nickel ore deposits - Wikipedia

Lateritic nickel ore deposits are surficial, weathered rinds formed on ultramafic rocks. They account for 73% of the continental world nickel resources and will be in the future the dominant source for the mining of nickel. Genesis and types of nickel laterites. Lateritic nickel ores formed by intensive tropical weathering of olivine-rich ultramafic rocks such as dunite,

Processing of Nickel Laterite Ores on the Rise

SX-EW, or the Solvent Extraction – Electrowinning approach to lateritic ore beneficiation, is a hydrometallurgical method that relies on leaching, extractants, and electrowinning to produce nickel from ore. This process is often referred to as Leach Solvent Extraction – Electrowinning for its employment of a leaching step.

The benefit of treating a laterite ore pyrometallurgically is that you utilise a greater percentage of the resource as the iron and nickel become a product, by way of example for 1,000,000 tonnes of ore mined, you might make 300,000 tonnes of product with a nickel grade of 6-10%. The remaining residue is usually a dry Limestone type material that is inert and can be used for

Nickel-Cobalt Laterites—A Deposit Model - USGS

There is evidence that the production of Ni and Co from laterites is more energy intensive than that of sulfide ores, reflecting the environmental impact of producing a Ni-Co laterite deposit. Tailings may include high levels of magnesium, sulfate, and manganese and have the potential to be physically unstable. First posted September 20, 2013

Nickel and Cobalt Production - ScienceDirect

01/01/2014  The production of nickel and cobalt from primary sources involves beneficiation, and hydrometallurgical and pyrometallurgical processing. Nickel is recovered from lateritic oxides either as ferronickel from saprolite ores or as an intermediate mixed sulfide or hydroxides from limonite ores. Sulfide ores are converted into matte.

Nickel: Caught Between a Rock and a Hard Place

The ban on shipments of nickel laterite ore from Indonesia, due in January 2014, has been seen by some as a potential game changer and a bullish factor for nickel. Over time, we believe the move by the Indonesian authorities is likely to alter the nickel market’s dynamics markedly but not in the way many think: We expect a de facto ban will take place but that it will be relaxed in effect ...
