extraction of metals introduction

Some copper ores can be converted into copper(II) sulphate solution by leaving the crushed ore in contact with dilute sulphuric acid for a long time. Copper can then be extracted from the copper(II) sulphate solution. But, in many cases, it is possible to separate the metal compound from unwanted rocky material by physical means.
