Solar et al. (2008) noted two trends in nickel laterites processing, one favoring high-grade ferronickel (35% to 40% Ni) and the other favoring lower grades (20% to 25% Ni). Because the ores processed vary widely in terms of nickel content and other components, it is natural that both lower and higher reduction degrees are used.

tracting metals from low grade ores. The nickel and cobalt deposits of significant importance in India occur only in the lateritic profile developed over the ultramafic complexes in Sukinda Valley of Orissa. These are the weathered profiles of dunitic ultramafic rock bodies and occur as overburden material in association with chromite ore deposits.
In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the Sherritt-Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then ...
Nov 09, 2018 The leaching process could be applied in the mining process to obtain nickel, copper, and cobalt from ores, where purification step is required due to the presence of impurities. Among these complex mixtures of several metals, a selective recovery is the key for a suitable separation process.

Traditional nickel laterite processing techniques use large quantities of sulphuric acid at high temperatures and pressures, resulting in expensive waste treatment and disposal of the chemicals used in the extraction process. Nickel laterites are becoming a priority for mining companies as traditional nickel sulphide reserves are depleted.
Introduction. Nickel (Ni) is an important metal in modern infrastructure and technology, with major uses in stainless steel (. 58%), nickel-based alloys ( 14%), casting and alloy steels ( 9%), electroplating ( 9%) and rechargeable batteries ( 5%) (Eramet, 2009, Barnett, 2010).. Economic Ni resources are found in either sulfide or laterite-type ores.
About 60% of the world 2009 nickel production of 1.4 million tonnes was derived from sulfide ores, but an ever-increasing proportion is coming from other ores (such as laterites, in which nickel is present in an oxy-hydroxide or silicate matrix). Indeed, over 70% of the world reserves of nickel are lateritic.

Local subcontracting therefore represents a process of nego-tiation and is situated between circula-tion of rent and local governance (ibid. 2012).

From laterite ores. Being free of sulfur, laterite nickel deposits do not cause a pollution problem as do the sulfide ores, but they do require substantial energy input, and their mining can have a detrimental effect on the environment (e.g., soil erosion). The range of process options is limited by the nature of the ore.
Nickel mining Nickel-containing ores are currently mined in more than 25 countries worldwide. The Asia Pacific region accounts for more than 70% of global nickel mine production. Indonesia, the Philippines, Russia, Australia and Canada are the biggest nickel producers.
Nickel smelting Extraction and purification Nickel is recovered through extractive metallurgy it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of the impurities.

process flowsheet into which the new separation process is inserted. After the initial leaching process of the nickel ore or concentrate, and subsequent liquid/solid separation, purification is needed to remove a) Copper, if present in commercial quantities, by solvent extraction.
After mining, nickel ores are further processed to upgrade their nickel contents from 1-4% typical of the ores to concentrates with grades in the range 10-20%. Concentration involves crushing the ore and separating nickel-bearing from other minerals using various physical and chemical processing methods.
Lateritic ores are formed by prolonged weathering of ultramafic rocks. The laterite deposits exhibit graded layers of ore, with high iron, low nickel ore on top and low iron, high nickel ore below. The low iron ( 15 % Fe) ores containing 1.7 2.3% Ni are treated by pyrometallurgical processes to
