The percentage of an element produced in the top producing country. It was so called in this early mining region because it was very difficult to smelt without oxidising and smelting would release the associated arsenic vapours which would lead to pretty troublesome or even deadly processing conditions for the worker. While the purified metal is a grey steel color, the salts that include cobalt atoms are many shades of blue. I always find the question 'what's your favourite element' a difficult one. Cobalt is widely present on the earth crust, in combination with other minerals and in natural water. It is given by the ratio of the pressure on a body to the fractional decrease in volume. For more information on the Visual Elements image see the Uses and properties section below. This element is produced by smelting, which is a hard, lustrous, gray metal.
