Extraction Of Copper Ppt

In industry, an ore is a rock that contains enough metal to make mining and extraction economical. However, the value of ores changes over time due to society and technology. For example, rocks containing only 5 copper would have been considered unprofitable in the 19 th century. Today, most copper comes from ores containing 0.4 to 1 copper.

    If copper is heated it does not burn but forms a black coating of copper oxide. Silver and gold does not react with oxygen even at high temperature. Some metals like magnesium, aluminium, zinc, lead etc. forms an oxide layer over it which prevents further oxidation. They are called self protecting metals.
