Nickel is one of important metals widely used in alloy, battery, catalyst, coin, and electronic device, just to name a few. The nickel sulphide minerals of economic interest include pentlandite ((NiFe)9S8) and millerite, which are associated with a greater abundance of pyrrhotite (Fe8S9). Chalcopyrite is typically associated with nickel sulphide minerals that must be separated to a copper bearing concentrate with low nickel grades to facilitate efficient copper smelting.

镍是一种重要的金属，广泛应用于合金、电池、催化剂、硬币和电子设备，仅举几例。具有经济价值的镍硫化物矿物包括镍黄铁矿((NiFe)9S8)和千里石，它们与更丰富的磁黄铁矿(Fe8S9)有关。黄铜矿通常与硫化镍矿物伴生，必须将其分离为低镍品位的含铜精矿，以促进有效的铜冶炼。
