General Information. Occurrence -Ni has an abundance of 0.016% in lithosphere and is the twenty-second element in abundance in the earth’s crust. The chief ore is Pentlandite [(NiFe) 9 S 8].]. Ni also occurs in meteoric iron, josephinite, awaurite and it occurs in arsenates, antimonates, silicates, sulfides and phosphates. Canada is the main refiner of the metal.
2020-05-05· Nickel was found when a copper-coloured ore did not make copper metal. Later it was found out that the ore was actually a nickel containing ore. Nickel was isolated as a metal in 1751. At first, the copper colored nickel ore was the only source. Later, it was made as a byproduct of cobalt blue making. Preparation

2013-10-10· There are two commercial classes of nickel ore, the sulfide ores (pentlandite and pyrrhotite) and the silicate-oxide. Most nickel is produced from the sulfide ores, and the two largest producers, Canada and the Russian Federation, account for 20–25% each of total annual production, which was 784.82 thousand tonnes in 1988 (5).
Since 1988, Australian-based company ‘OREAS’ has specialised in the development of certified reference materials (CRMs) for the mining and exploration industries. OREAS combines a blend of innovative technology with world’s best practices to maintain its position as a leading producer of reference materials.

2020-05-13· Nickeline or niccolite is a mineral consisting of nickel arsenide (NiAs) containing 43.9% nickel and 56.1% arsenic.. Small quantities of sulfur, iron and cobalt are usually present, and sometimes the arsenic is largely replaced by antimony.This last forms an isomorphous series with breithauptite (nickel antimonide).
ASTM's analytical chemistry standards are instrumental primarily in stone analysis of various metals, alloys, and ores. These analytical chemistry standards present various test methods and techniques in determining the stone composition of alloys and ores which include molecular absorption spectrometry, X-ray emission spectrometry, optical emission vacuum spectrometry, atomic
