Improved beneficiation of nickel and iron from a low-grade ...

01/03/2020  As is well known, the process of direct reduction and magnetic separation is effective route to deal with low-grade saprolite laterite, but generally limited by the reduction of nickel (iron)-bearing minerals and growth of Fe-Ni alloy particles in the reduction process, causing the low recovery of nickel and iron. 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

There are different methods for beneficiation of laterite nickel. Extraction of nickel from low-grade reserves usually is done by with metallurgical methods such as pyrometallurgy, hydrometallurgy, and physical methods. In approximately all of the pyrometallurgical processes three thermal phases exist,

Nonmolten state metalized reduction of saprolitic laterite ...

20/05/2020  The newly generated fayalite was the primary reason for the low iron recovery. Meanwhile, a small amount of sporadically embedded ferronickel in the tailings was responsible for the loss of iron and nickel. The proposed innovative technology can realize nonmolten metalized saprolitic laterite ores and effective beneficiation of nickel and iron.

Effective Separation and Beneficiation of Iron and ...

Through the reduction roasting–magnetic separation process, most of the iron is beneficiated in the concentrate, and nonmagnetic minerals such as FeS and CrS remain in the tailings. Consequently, the separation and beneficiation of iron and chromium occur. The process is economically feasible and environmentally friendly and thus has great potential for the industrial-scale recycling of laterite

Beneficiation of nickeliferous laterite by reduction ...

01/05/2012  Nickel in nickeliferous laterite is closely associated with iron oxide and silicate minerals as isomorphous substitution for iron and magnesium in the lattice. Laterites are not amenable to beneficiation by physical methods due to their complex mineralogy (Dalvi et al., 2004, Warner et al., 2006). Thus, for laterite ores treatment, pyrometallurgical or hydrometallurgical methods are usually

of alternative ways of beneficiating the iron ore. This paper reports on the study that was done to concentrate low grade iron ores. Raw biomass / low grade iron ore mixed in the ratio of 1:10 in a reducing environment was heated in a controlled air condition to increase the magnetic susceptibility of iron in the ore. The magnetic portion of the resulting product was separated using a horse shoe-magnet.
