copper extraction and purification chemguide

Extracting copper from its ores. The copper(II) ions in the chalcopyrite are reduced to copper(I) sulphide (which is reduced further to copper metal in the final stage). The iron in the chalcopyrite ends up converted into an iron(II) silicate slag which is removed. Concentration of the copper(II) sulphate solution by solvent extraction.

Demonstrations Copper + Nitric Acid

Copper + Nitric Acid . Copper is a reddish brown metal, widely used in plumbing and electrical wiring; it is perhaps most familiar to people in the United States in the form of the penny. (Although since 1983, pennies are actually made of zinc surrounded by a paper thin copper foil to give them the traditional appearance of pennies.)
