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.

Global Trends And Environmental Issues In Nickel Mining

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.


Extracting Metals From Sulfide 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.
