Cobalt displays chalcophile and siderophile properties and is partitioned into a number of sulphide and sulpharsenide phases. It forms several rather rare minerals, including smaltite Co,NiAs22.5, cobaltite Co,FeAsS and linnaeite Co,Ni3S4, and is present as an accessory element in olivine, pyroxene, amphibole, mica, and sphalerite.
The mica group represents 37 types of minerals, with layered structures that allow them to be split into thin flakes or sheets. Mica is largely known for its application in cosmetic products and paint. It is also used for insulation and heat resistance, and can by found inponents of electronic and
