THE EXTRACTION OF METALS - AN INTRODUCTION

Copper is much rarer, but fortunately can be found in high-grade ores (ones containing a high percentage of copper) in particular places. Because copper is a valuable metal, it is also worth extracting it from low-grade ores as well.

Copper extraction - Wikipedia

Extraction Ores are first mechanically crushed and ground so that nearly all copper mineral particles are freed from the gangue. Flotation by the injection of air and violent agitation is carried out with the pulverized ore held in suspension in water, to which surface-active agents have been added.

Copper Mining and Extraction: Sulfide Ores

Copper can be extracted from its ore by: Underground: sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. Open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid.
