Mineralogy and crystal chemistry of a low grade nickel

Apr 01, 2012More nickel laterite ores are imported into China because of the depletion of domestic nickel sulfide resources. Consequently, it is of great importance to the Chinese economy to effectively utilize low grade nickel laterite ore [7]. Nickel laterite ores are formed by the weathering of olivine bedrock in tropical to sub-tropical climates [8,9].

Lateritic nickel ore deposits

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. As such, certain steel smelters in China have developed a process for blending nickel limonite ore with conventional iron ore to

Nickel in Drinking

The primary source of nickel in drinking-water is leaching from metals in contact with drinking-water, such as pipes and fittings. However, nickel may also be present in some groundwaters as a consequence of dissolution from nickel ore-bearing rocks. Nickel is used principally in its metallic form combined with other metals and non-metals as

Uses of Nickel

Where Does Nickel Come From? Nickel is the fifth most abundant element in the Earth, but most of that nickel is located in the core, more than 1,800 miles below the surface.In Earth's crust, two major types of ore deposits supply most of the nickel used today: magmatic sulfide deposits (such as the pentlandite and pyrrhotite deposits found at Norilsk, Russia; Sudbury, Ontario, Canada; and

How to Identify Valuable Rocks

Mar 13, 2018The harder a mineral is, the more likely it is to be valuable. If you can scratch the mineral with your fingernail, it has a hardness of 2.5 Mohs, which is very soft. If you can scratch it with a penny, its hardness is 3 Mohs, and if it takes a piece of glass to scratch it, the hardness is 5.5 Mohs.

Difference Between Nickel and Stainless Steel

Oct 14, 2015Nickel: Nickel is a pure chemical element; it is also a member of transition metal group. Nickel has five naturally occurring stable isotopes; 58 Ni, 60 Ni, 61 Ni, 62 Ni, and 64 Ni. The most abundant isotope is 58 Ni, and its natural occurrence is about 68.077%. Stainless Steel: Stainless steel is a combination of iron (Fe), Chromium (Cr) and

nickel

nickel (n.) whitish metal element, 1755, the name was coined in 1754 by Swedish mineralogist Axel von Cronstedt (1722-1765) from shortening of Swedish kopparnickel copper-colored ore (from which it was first obtained), a half-translation of German Kupfernickel, literally copper demon, from Kupfer (see copper) + Nickel demon, goblin, rascal (a pet form of masc. proper name Nikolaus

Nickel Statistics and Information

Nickel Statistics and Information. Nickel (Ni) is a transition element that exhibits a mixture of ferrous and nonferrous metal properties. It is both siderophile (i.e., associates with iron) and chalcophile (i.e., associates with sulfur). The bulk of the nickel mined comes from two types of ore deposits:

Nickel (IARC Summary Evaluation, Volume 49, 1990)

Nov 12, 1997Among hard-rock sulfide nickel ore miners in Canada, there was some increase in lung cancer risk, but exposure to other substances could not be excluded. In studies of open-cast miners of silicate-oxide nickel ores in the USA and in New Caledonia, no significant increase in risk was seen, but the numbers of persons studied were small and the
