The increasing demand for stainless steel and the scarcity of sulfide nickel ore affect the increase of laterite nickel ore processing. One of the processes that has been proven can be applied to process laterite nickel ore is direct reduction. In the direct reduction, the reduction atmosphere was adjusted by controlling the volume of CO and CO2 from carbon source materials, such as coal.Read More

Geology Nickel laterites are originated from the weathering of ultramafic rocks in humid tropical to sub- tropical environments. During the weathering process Fe and Ni are enriched in the topmost parts while other elements are leached. Lateritic ore deposits can be identified as deposits of 3 main layers with different levels of weathering.
So far, no effective physical beneficiation method has been found to enrich laterite nickel ore. Laterite ore can be divided into two types One is the limonite type, which is contained in the surface of laterite ore, in which nickel occurs mainly in the solid melt state of nickel oxide and iron oxide, such as (Fe,Ni)O(OH) n H 2 O and the.
For example, in New Caledonia, nickel is concentrated either in fine-grained laterite where goethite is the main nickel bearer (lateritic ore) or below the laterites as mixtures of hydrous Mg–Ni silicate and goethite (saprolite ores) (Dublet et al., 2012).
Feb 06, 2012 In lateritic nickel ore, nickel is associated with iron phase where as cobalt is associated with manganese phase. Natural Fe(III) oxides are high in surface area and are reactive. Fe(III) oxides adsorb a wide range of metal cations and anions by complexation to surface hydroxyl groups.
Typical nickel laterite ore deposits are very large tonnage, low-grade deposits located close to the surface. They are typically in the range of 20 million tonnes and upwards (this being a contained resource of 200,000 tonnes of nickel at 1 ) with some examples approaching a billion tonnes of material.

Lateritic Nickel Ore Processing. 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.
For a nickel oxide ore, 1 ore sample was treated by sulfuric acid leaching and 2 ore sample was treated by ammonium sulfate roasting-sulfuric acid leaching through exploring experiments. The leaching rate of 92.04 with l nickel oxide ore and the leaching rate of 72.36 with 2 nickel oxide ore were obtained by conducting the conditional experiments of sulfuric acid concentration, leaching.
As nickel continues to play a greater role in meeting future sustainability goals while sulfide ore sources dwindle, laterite ores will increasingly be used to satiate nickel demand. The wet and sticky nature of laterites, however, requires the ore to be dried before it can move on to further processing in most cases, and for this, the rotary.
Jan 28, 2016 FERRO NICKEL ORE- A recent development in the extraction of nickel laterite ores is a particular grade of tropical deposits, typified by examples at Acoje in the Philippines. This ore is so rich in limonite (generally grading 47 to 59 iron, 0.8 to 1.5 nickel and trace cobalt) that it is essentially similar to low-grade iron ore.
