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.
The ore used for the study was nickel laterite obtained from the major deposits of Sukinda mines, Orissa, India. The ore was sieved to a mean particle size of +45 μm. Roasting was done at 400 °C in a muffle electric furnace for 5 h in a silica crucible and it converts goethite (FeOOH) into hematite (Fe 2 O 3).

The Bureau of Mines investigated the flotation responses of two copper nickel ore samples from the Duluth Complex with the objective of recovering bulk sulfide concentrates. One of the ores studied was taken from a test pit; the other was taken from a test shaft. The samples were quite similar except that the pit sample analyzed pct Cu and pct Ni and the shaft sample analyzed ...
