01/09/2019 The densities of the nickel bearing minerals in the tested laterite ores are relatively close, but they are still different and may be separated via density separation. For example, the Fe based minerals (i.e. siderite, hematite, magnetite, and goethite) have a density of about 4.0–5.0 g/cm 3 while silicate minerals (i.e. serpentine, quartz and feldspar) have a density of around 2.5 g/cm 3 .

CNA Nickel On-line Nickel Ore Analyzer Malvern

Nickel, from sulfide nickel ores, is extracted by a process where the nickel sulfide mineral is freed from gangue by crushing and grinding, after which it is separated by flotation and finally smelted or roasted. Extraction of nickel from the laterite ores is carried out either by pyrometallurgical (for saprolite) or hydrometallurgical (for limonite) process.

The value of mineralogical analyses for base

Processing of laterite nickel ore is more complex. Crushed and ground ore is leached under high pressure using sulphuric acid. After the separation the nickel liquor goes straight to a refinery for pure metal production. Alternatively intermediate nickel hydroxide (or sulphide) is produced that is further processed in a nickel refinery.
