Nickel is often extracted from its ore by roasting at high temperatures. In some cases this is enough to separate the nickel in other cases strong chemicals are used to separate the ore. Nickel is also refined using electro refining. In this process the ore is placed in a nickel salt solution and an electrode placed in the mixture.
