Cobalt is found in low-grade ore; therefore small amounts of cobalt must be separated from large amounts of waste. Depending on the minerals in the ore different methods of extraction are used. To obtain cobalt you must first roast the cobaltite to change the cobalt to Cobalt Oxide (CoO) then the cobalt is freed from oxide by heating it with coke (carbon) to take away the oxygen, industrially, however, it is normally produced as a by-product from the production of copper, nickel, and lead.

Thermally resistant alloys, called superalloys, containing cobalt are used in industry

About 70% of the world's cobalt is used in alloys. Cobalt steels are not made in Australia. There are 2 main cobalt alloys the High Temperature and Magnetic alloys. High Temp. Alloys are made with about 5-10% cobalt and they go to make Gas turbines, jet propulsion engines and high-speed cutting t
