The main mineral types include laterite (saprolite, limonite) and garnierite. Goro Plateau is the most important area as it hosts a nickel deposit with total proven and inferred resources estimated at about 124 million tonnes of high-grade laterite ore …
The Morowali deposit is developed on a laterite profile due to ophiolite weathering, with saprolite, limonite, and ferruginous cap horizons from the bottom to top. Based on the occurrence of garnierite as the main ore, occurring in the saprolite horizon, it can be classified that the ore deposit is hydrous Mg silicate-type.
Currently used as a field-term unidentified massive hydroxides and oxides of iron, with no visible crystals, and a yellow-brown streak. 'Limonite' is most commonly the mineral species goethite, but can also consist of varying proportions of lepidocrocite, hematite and/or maghemite, along …
Uses of Limonite. Limonite has been used by people since prehistoric times. Their first use of limonite was probably as a pigment. It is found in many Neolithic pictographs, and throughout history it has been one of the most important pigments for creating paints in the yellow to brown color range known as ocher.Its use as a pigment continues today.
