AN ASSESSMENT OF PENTLANDITE OCCURRENCE IN THE

pentlandite in the ore occurs as exsolutions in the pyrrhotite and the grain sizes ranges from 8 to 38µm. about 25% of the nickel bearing pentlandite is medium grained and subhedral. This kind of pentlandite occurs along the cracks of pyrrhotite or as inclusions in pyrrhotite. The rest of pentlandite present is disseminated in the gangue matrix.

Smelting Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal. It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

Sulfide Ores an overview ScienceDirect Topics

The source of the sulphur in these ore bodies is either from the magma itself or from the pre-existing rock where it was present as sulphate. The most common nickel mineral in these ores is pentlandite, (Ni,Fe) 9 S 8. The atomic ratio of nickel to iron in pentlandite ranges between 0.34 and 2.45. Most often, though, it

5. PRODUCTION, IMPORT/EXPORT, USE, AND DISPOSAL

Pentlandite (Ni,Fe)9S8 is the principle ore. Pentlandite often occurs along with the iron mineral pyrrhotite and the copper mineral chalcopyrite, and part of the smelting and refining process separates the copper and iron from the nickel. The ore is concentrated by physical means (i.e., flotation and magnetic separation) after crushing.
