Mineralogy plays an important role during flotation to separate nickel sulfides from gangue minerals. Apart from usual "trouble-makers", like talc

Metal, Iron, & Nickel | Some Meteorite Information

Because they contain much iron-nickel metal, all metal-bearing meteorites are attracted to a magnet. The concentration of nickel in iron meteorites and the metallic part of pallasites, typically 5-30%, is much greater than that in industrial metals except for high-nickel steels. The concentration of nickel in industrial iron is usually <1%.

Nickel Chemistry -

 · Nickel is a hard silver white metal, which occurs as cubic crystals. It is malleable, ductile and has superior strength and corrosion resistance. The metal is a fair conductor of heat and electricity and exhibits magnetic properties below 345°C. Five isotopes of nickel are known. In its metallic form nickel is chemically unreactive. It is

What is Concentration of Ore? Definition, Physical

The concentration of ore is a method of eliminating gangue particles or other impurities. Ore-dressing and benefaction are the alternative names for the term concentration of ore. To obtain a pure metal from ore, the method of ore concentration is a very crucial step. For the extraction of metal, it is necessary to separate ore from the gangue particles. Ore found in the earth

Nickel Deposits of - USGS

nickel ore deposits are closely associated with mafic and ultramafic in­ trusive rocks, and the nickel in the ore bodies was probably derived either from the intrusives themselves or from similar rocks at depth. Thus the original source of most of the nickel ore bodies found in North America and elsewhere in the world was probably the mantle. TYPES OF DEPOSITS All the
