The selective flotation of pentlandite from a nickel ore - ScienceDirect. Nickel sulphide ores containing pentlandite, pyrrhotite and talc have minerals in the ore and the influence of the grinding medium on iron sulphide flotability.
Only about 1.4 million tonnes of new or primary nickel are produced and used annually in the world, compared with over 10 million tonnes of copper and nearly 800 million tonnes of steel. There are many different nickel ores and many different ways to extract the nickel and other metals from those ores.

Extraction of Nickel and Cobalt from Sulfide Ores Request PDF. Request PDF on ResearchGate Extraction of Nickel and Cobalt from Sulfide Ores This chapter All the nickel in nickel sulfide ores occurs in the mineral pentlandite There are two industrial methods used for smelting nickel sulfides.
The bulk of the nickel mined comes from two types of ore deposits: laterites where the principal ore minerals are nickeliferous limonite [(Fe,Ni)O(OH)] and garnierite (a hydrous nickel silicate), or; magmatic sulfide deposits where the principal ore mineral is pentlandite [(Ni,Fe) 9 S 8].
Nickel mineralization in the ore such as pentlandite, violarite, millerite awaruite, and asbolanewas determined. Due to the complex structure of mineralization, a combination of gravity-separation and flotation methods was applied for the concentration of nickel sulphide and oxide ores.
This creates a fine, pure nickel powder. Lateritic Ore Processing. The high iron content of lateritic ores makes smelting the preferred method of nickel extraction. Lateritic ores have high moisture content that requires drying the ores in kiln furnaces. These kiln furnaces produce nickel oxide from the lateritic ores.
important ore minerals are the sulphides pentlandite and pyrrhotite, and the oxide garnierite (Table 1). Other nickel minerals include niccolite, millerite, breithauptite, choanthite, gersdorffite and ullmannite. Nickel may also be present in goethite (limonite) (Ni,Fe)O(OH).nH 2 O. Nickel occurs as a metal in meteorites and often serves as one
