Factors Affecting Exploitation of Mineral Resources around

Ores vary in their metal content. Generally the higher-grade ores are more economic to work, not only because they yield large amount of metal but also because their higher metal content makes them easier and cheaper to smelt. Minerals of high value such as gold, diamonds, copper, uranium, can often be mined at very high cost, because they are in great demand and fetch high prices. (ii) Size
