Garnierite is a green mineral, ranging from light yellow-green to dark green. [3] [5] The color comes from the presence of nickel in the mineral structure for magnesium. [4] Noumeaite (later determined to be a member of the garnierite family) varies in hardness, from soft and brittle to hard enough to carve into figurines and the like. [11]

The first report of Annabergite by Axel Fredrik Cronstedt from 1758 erroneously identifies it as a nickel oxide mineral and assigned it the latinized name Ochra niccoli, while Wallerius gave it the name nickel bloom in 1778.
The DNi process uses nitric acid, instead of sulphuric acid, to extract the nickel within a few hours and then the nitric acid is recycled. The DNi process has the major advantage of being able to treat both limonite and saprolite lateritic ores and is estimated to have less than half the capital and operating costs of HPAL or Ferronickel ...
Until 1866 he traveled the island and discovered a new green nickel ore, having a large weight percent of nickel oxide, [4] which was named garnierite in his honor by his peers.
