The mineral cobaltite, CoAsS, has a brittle fracture, and exhibits good cleavage in three directions.
CoAsS
It is a solid found as the ore cobaltite and most abundantly in veins of copper and nickel ore.
Cobaltite is a sulfide mineral composed of cobalt, arsenic, and sulfur, CoAsS. Its impurities may contain up to 10% iron and variable amounts of nickel.The mineral is mostly found in the Cobalt District, Ontario, Canada; Sweden; Norway; Germany; Cornwall, England; Australia; Democratic Republic of the Congo; and Morocco.It occurs in high-temperature hydrothermal deposits and contact metamorphic rocks.I only know this.
Cobalt minerals are cobaltite, skutterdite, glaucodot, saffronite; cobalt is also a by-product of copper and nickel processing.
