One of the ore types mined at Nkomati nickel mine is the main mineralized zone (MMZ). The MMZ ore is hosted in the Uikomst complex, a Ni-Cu-PGE-Cr- mineralized, layered basic to ultra-basic intrusion which hosts commercially viable magmatic base-metal sulphides (De Waal et al., 2001). ... The MMZ ore is a heterogeneous sulphide mineral …

ARM owns Nkomati Nickel on a 50/50 basis with Norilsk Nickel (Nornickel), the Russian platinum group metals producer which has seen its share price dive nearly 90% in the last month following the beginning of Russia's invasion of Ukraine. ARM and Nornickel decided to put Nkomati in mothballs in 2019 after it reported losses.

A process mineralogical study based on three texturally and mineralogically different chromite-bearing ore types at the Nkomati nickel mine was undertaken, with focus on chromite. Chromite is a by-product of the Ni-Cu-Co-PGE ore at Nkomati Nickel mine. These being the PCMZ_MG (medium-grade Ni-Cu sulphide silicate ore with …

(MMZ) is comprised of a solid sulphide ore body with a relatively high nickel content. The Nkomati Deposit also contains a Peridotite Chromite Mineralisation Zone (PCMZ) with a lower metal content vs MMZ and a relatively high chromium content. In 2018, total ore mined by Nkomati reached 3.1 mt (attributable to the Group's 50% shareholding)

The mineralogy and texture of Ni-sulfide ores at the Nkomati nickel mine are highly variable, and this results in often erratic nickel recovery at the mine. The variability of the ore presents an opportunity to study the influence of grind size on the flotation-based recovery of Ni in highly heterogeneous sulfide ores, which would be applicable ...
