1991-11-1 Pentlandite circuit Another unusual feature of the Thompson concentrator circuit is the pro- duction of a high grade nickel concentrate that is locally identified as "pen- tlandite" concentrate. This concentrate typically analyzes 30% nickel and is produced solely for sale to Sherritt-Gordon where it is treated in their Fort Saskatchewan refinery.

AN ASSESSMENT OF PENTLANDITE OCCURRENCE IN THE
2016-2-15 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.

CN105498955A - Simple method for extracting
The invention discloses a simple method for extracting pentlandite monominerals. The method is characterized in that copper-nickel sulphide ore is used as a raw material, and a magnetic field of which the strength gradually increases is applied to the copper-nickel sulphide ore through a permanent magnet, so as to achieve stage-by-stage magnetic separation of the copper-nickel sulphide ore.

THE DESIGN AND IMPLEMENTATION OF THE NICKEL
In order to alleviate problems associated with cementing of ore in transfer chutes and bins, the crushing circuit was simplified to single stage jaw crushing, directly feeding the SAG mill. This reduces the capital and operating cost of the crushing circuit significantly compared with the conforming 3 stage crushing and ball milling design.
