The nickel industry is different from other metal industries. Various production routes are applied to create nickel products. All nickel products analyzed undergo ore mining as the first production step. The ore is the further processed in either ore beneficiation (sulphidic ore) or ore preparation (oxidic ore) and in the following a "primary

To improve beneficiation of nickel and iron from low-grade saprolite laterite with 1.29 wt.%Ni and 16.31 wt.%Fe, co-reduction with limonitic laterite ore and basicity optimization were adopted as ...

The collectorless floatability of Enonkoski low grade ore (0.3% Ni) at alkaline and slightly acid pH after grinding in ceramic and steel mills is shown in Figs. 3 and 4. The sulphide minerals in nickel ores are easily floatable without a collector in acid pulp due to oxidation and, therefore, their separation is not possible at low pH.

Nickel is a kind of silvery white ferromagnetic metal firstly separated by Swedish mineralogist A.F. Cronstedt in 1751. It is in the eighth group of the fourth period in the periodic table of elements, with atomic number of 28, atomic weight of 58.71, density of 8.9 g/cm 3 (20 ℃), melting point of 1455 ℃, and boiling point of 2915 ℃. The most stable oxidation state of nickel …
