Carbon occurs both as a free element and in combined form It also occurs as carbon dioxide a minor but crucially important constituent of the atmosphere In addition to its natural occurrence as the free element carbon is widely distributed in the form of coal and petroleum and as carbonates of the more electropositive elements successfully used for the beneficiation of certain types of gold ores in Turkey It contributes to the substantial development of a sustainable gold mining sector in that country and has the potential to help fostering sustainable supply of raw materials in other countries within Europe
