Laterite ore is a valuable resource due to its high content of metals essential for modern technology, including nickel, iron, and cobalt. However, extracting nickel from laterite ores is challenging due to their complex mineral composition and low nickel concentrations. This study examined the leaching behavior of pre-roasted laterite ore …

In this paper, the flotation behaviour of nickel-copper ores processed in the Sudbury area is discusse~ with emphasis on the effect of oxidation on individual minerals, pnmarily pyrrhOlite. In general, moderate oxidation of a freshly ground ore promotes the flotability of all principal sulphides in the ore leading to a bulk flotation concentrate.

1. Introduction. While there are over 45 different nickel minerals, only a few of them are of economic importance to the minerals industry (Dana and Ford, 1966).The principal nickel mineral in nickel sulphide ores is pentlandite ((Ni,Fe) 8 S 9) while the less common nickel sulphides include millerite (NiS), violarite (Ni 2 FeS 4), polydymite (Ni 3 …

Highlights High temperature experiments demonstrated that selective sulphidation is feasible. Sulphides were submicron in size but could be physically upgraded. Nickel sulphides responded to flotation and grades of 6–8% were achieved. Low nickel grade was due to fine particle entrainment. Low nickel recovery was due to issues with …
