Major Mines Projects

Ni occurs in solid solution largely in serpentine with subordinate amounts in goethite (=limonite) and vermiculite. Minor amounts of various green silicates, "gamierites" intergrown with chalcedonic quartz, are seen locally in Onca saprolite; grains of possible nepouite contained 13-19 wt% Ni have also been identified in mineralogical studies.

Vermiculite

Vermiculite is a hydrous phyllosilicate mineral which undergoes significant expansion when heated. Exfoliation occurs when the mineral is heated sufficiently, and commercial furnaces can routinely produce this effect. Vermiculite forms by the weathering or hydrothermal alteration of biotite or phlogopite. Get price
