Calcium. Very common in rock forming minerals, like anorthite, calcite, dolomite Pollution of land by heavy metals is a result of the mining of ores to extract important resources that are found in rainforests around the world. Extracting.

Extracting copper. Where does copper come from?

An ore is a rock that has enough metal in it to make it worth extracting the metal. Over 50% of the World's copper comes from chalcopyrite and bornite. This means that huge lumps of copper metal are found buried in the ground as nuggets. mineral, calcium, carbon, chlorine, copper, hydrogen, iron, oxygen, silicon
