Translations

кобальтинкобальтит

cobaltite

(kō`bôltīt, kōbôl`tīt), opaque, silver-white, sometimes reddish or grayish mineral of the pyrite group, a compound of cobalt, arsenic, and sulfur, CoAsS. It occurs in crystals of the cubic system, also in compact to granular masses. It is an important ore of cobalt, found chiefly in Sweden, Norway, India, and Azerbaijan.

Cobaltite

a mineral, cobalt sulfoarsenide, CoAsS; one of the complex sulfoarsenides. Cobaltite contains 35.41 percent Co, 45.26 percent As, and 19.33 percent S; the cobalt may be partially replaced by iron and nickel (varieties of ferrocobaltite and nickel cobaltite). Cobaltite crystallizes in a cubic system, existing as crystals of cubic habit, as well as in more complex combined forms (pentagonal dodecahedron, octahedron, and so on). Granular aggregates are the most common. Cobaltite is yellowish white in color, tinged with pink; it is nontransparent and has a metallic luster. Hardness on the mineralogical scale, 5.5; density, 6,100–6,400 kg/m³. Cobaltite usually occurs in contactmetasomatic deposits together with pyrrhotite, pyrite, arsenopyrite, chalcopyrite, and other sulfides, in hydrothermal gold-quartz lodes, and in lodes containing Co-Ni-Ag-Bi-U formations. Cobaltite is one of the main ore minerals for the preparation of cobalt and its alloys and compounds.
