Abstract We report here data on the pH, electrical conductivity (EC) and environmental magnetic properties (χ lf, χ fd, χ ARM, IRMs at different field strengths) of modern tropical lateritic soils from Aribail, Miyapadavu and Uliyathadka, all in the Kasaragod District of Kerala, southern India.This study aims to characterize the rock magnetic properties of lateritic soils that formed under ...
Since, the ore contains both Ni and Fe, the calcination of laterite is effective in altering the crystalline structure of Fe species and therefore its magnetic properties, which in turn enable the selective concentration of nickel by magnetic separation that is an easy and environmentally-friendly technique.

Is Nickel Magnetic? The element Nickel (Ni) is one of the few ferromagnetic metals. Ferromagnetic means they are attracted to magnets and can be magnetized themselves. Most metals aren't magnetic with the exception of iron, nickel, cobalt, gadolinium, neodymium and samarium.
Nickel is found in two types of deposits; Nickel laterites and magmatic sulfide deposits.Although nickel Laterites make up 70% of the world's nickel reserves, few of them become producing mines. Over the last 60 years magmatic sulfide nickel deposits produced 60% of the world's nickel.
from the oxidic nickeliferous laterite deposits, as the global nickel sulphide resources are rapidly becoming more difficult to access. In comparison to sulphide ores, where the nickel-containing mineral can be readily concentrated by flotation, nickel laterites are not amenable to significant upgrading, due to their complex mineralogy.
Nickel - Uses, Pictures, Characteristics, Properties, Periodic Table. Nickel has been used since ancient times. Pure nickel was extracted by Axel Cronstedt from the ore niccolite (nickel arsenide, NiAs) in 1751.
propose that laterites developed from alteration of a peridotitic bedrock on Earth may display mineral similarities with some of the Martian bedrock underlying the regolith. The peridotitic laterites of the New Caledonia ophiolite provide excellent opportu-nities for geoscience investigations because numerous boreholes have been drilled
Gudulas K. MAGNETIC PROPERTIES OF CHROMIUM-CONTAINING LATERITES The spontaneous magnetic moment of chromite can be described by its own from the divalent metallic ions.
The mineral phases in more than 50 Ni laterite ores were determined before and after the ores were acid-leached in columns for more than 120 days. The selected ore samples have wide variations in initial chemical and mineralogical compositions and other properties, and their behaviour during treatment, including the proportions of Ni and Co extracted, exhibit similar extreme variations.
special magnetic and electronic properties [2, 3]. The major use of nickel is in the production of stainless and heat resisting steels, which accounts for 66 % of the total nickel consumption. However, 12 % of nickel is also used in the production of non-ferrous alloys, 5 % for steel alloys, 7 % for plating,
The other type of nickeliferous laterite is known as nickel silicate, which contains less than 30% iron, 30% silicon dioxide, and about 1.6% nickel. In general, laterite has high concentrations of iron, titanium, and aluminum oxides. With these low percentages, not all nickel recovery from laterite mining is economically feasible.
