nickel content in nickel ores

Nickel Ore - an overview ScienceDirect Topics

Because the ores processed vary widely in terms of nickel content and other components, it is natural that both lower and higher reduction degrees are used. Low reductions imply higher slag losses and lower nickel recoveries but also lower power and reductant requirements, whereas higher reductions imply the reverse ( Solar et al., 2008 ).

Nickel Statistics and Information - USGS

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:

Upgrading low nickel content laterite ores using selective ...

May 20, 2012  The processing of nickel laterite ore to produce ferronickel is energy intensive, especially when low nickel content ores are processed. The selective reduction–beneficiation of laterite ore to produce high nickel content nickeliferous concentrate and abandon gangue minerals before smelting potentially offers an effective pre-treatment to this process.

Nickel Ores Article about Nickel Ores by The Free Dictionary

The nickel content in sulfide ores ranges from 0.3 to 4.0 percent and more. The Cu:Ni ratio varies from 0.5 to 0.8 in low-copper ores and from 2 to 4 in high-copper ores. In addition to nickel and copper, considerable quantities of cobalt, as well as gold, platinum, palladium, rhodium, selenium, tellurium, and sulfur, are extracted from such ores.

NICKEL AND COBALT ORES: FLOTATION

The nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde ores renders them unsuitable for either direct smelting or hydrometal-lurgical extraction, thus requiring beneRciation. The usual method of nickel extraction from sulRde
