Nickel Laterites: The World's Largest Source of Nickel
Nickel is found in two types of deposits Nickel laterites and magmatic sulfide deposits.Although nickel Laterites make up 70% of the world's nickel reserves, few of them become producing mines. Over the last 60 years magmatic sulfide nickel deposits produced 60% of the world's nickel.

Nickel sulfide Wikipedia
Nickel sulfide is an inorganic compound with the formula NiS. It is a black solid that is produced by treating nickel(II) salts with hydrogen sulfide.Many nickel sulfides are known, including the mineral millerite, which also has the formula NiS.Aside from being useful ores, nickel sulfides are the products of desulfurization reactions, and are sometimes used as alysts.
Pentlandite: The mineral pentlandite information and pictures
Pentlandite is both an individual mineral, and the name of a mineral group. The Pentlandite group is composed of rare sulfides that have similar chemical structures, with Pentlandite being the most prominent member of the group. Pentlandite is named in honor of Joseph Barclay Pentland (1797–1873), a natural scientist from Ireland who first identified this mineral.

Synthesis of Novel Nickel Sulfide Layer‐Rolled Structures
Microtubes composed of rolled up layers of nickel sulfide can be prepared under mild conditions. The mechanism is proposed to involve self‐assembly of Ni(NH 3) 2+ 6 into ordered arrays via hydrogen bonding interactions with water, followed by conversion to NiS layers upon addition of CS 2. The layers then roll up when heated (see Scheme).
