Primary abundance variations of nickel, copper, and platinum group elements in magmatic-sulfide ore are controlled by the composition of the silicate magma and the mass ratio of silicate to sulfide liquid (Naldrett, 1989). In addition to sulfur, iron, nickel, copper, cobalt, and the platinum group elements (platinum, palladium, rhodium, ruthenium,

Steel Glossary | Glossary of Terms | Platts

In stainless steel, nickel is most associated with austenitic grades (typically 4-22% Ni). It is sometimes present in ferritic and martensitic grades, but at low concentrations. In duplex grades the Ni content can be up to about 7%. The LME is the basis of nickel pricing (as refined cathode, 99.8% Ni).

nickel Ore - SlideShare

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.
