Figure 1 presents the scope of nickel application according to data reported in [6]. The sulfide deposits in Russia and Canada are distinguished for relatively well-balanced mineral composition of ores. Principal ore minerals are pyrrhotine, pentlandite, chalcopyrite, and magnetite. Nickel is mainly presented with pentlandite (Ni, Fe)9S8.

Nickeliferous laterite ores are abundant, with experts estimating that they account for about 70% of known global nickel resources. They are also close to the surface, unlike sulfide deposits, which are mined at much greater depths. This abundance and ease of accessibility makes laterite ores an attractive option to the nickel industry.
Till recently there are no specific nickel ore deposits in India but the copper ores in Singh-bhum Dist., of Bihar contain minor quantities of nickel contributed by the nickel sulphides like, …
A nickel-copper sulphide concentrate was treated in a pilot plant at Warren Spring Laboratory during 1961, by a hydrometallurgical roast-leach-solvent extraction process devised to cleanly separate the metal values, and …
For oxide nickel ores that occur in the sulphide province of Western Australia, integration of oxide and sulphide processing routes will offer many economic and technological advantages. For other ores, non-metallurgical factors will have a significant influence on their future development.
Because the ores processed vary widely in terms of nickel content and other components, it is natural that both lower and higher reduction degrees are used. Low reductions imply higher …
While the smelter recovered the principal values, substantial losses of other metals and even penalties, such as for zinc at a lead smelter were common. With the high cost of the …
Nickel Statistics and Information USGS. 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 ].
The paper presents new data on mineral composition and geochemical peculiarities of ores from the Albazinskoe gold-bearing deposit (Khabarovsk region, Far East of Russia). Excepting earlier known ore minerals represented by sulfides of iron, arsenic, lead, zinc, and copper, authors have established about two tens of ore minerals, new for this deposit.
When the content of nickel ore is less than 3%, it is mainly accompanied by a large number of metal minerals and gangue minerals: the main metal minerals: pyrrhotite, Ni-pyrite …

–150+5 mm fraction is ~ 5%. To calculate neutralization potential of mineral waste, we assume calcite content as 0.5%. The content of 2– CO3 is 0.30%. Mineral waste of –150+5 mm fraction contains 3.5% of sulfur [12]. Mill tailings of current copper-nickel ores contain 0.7% of sulphide sulfur on average. When
The anticipated economic resources of nickel ores did not changed in 2021. The anticipated economic resources of nickel ores in Poland explored in B and C 1 categories amount to 17.21 million tonnes of ore with a metallic nickel content of 125.0 thousand tonnes (the limiting content of Ni in the deposit is 0.8%).
