Extracting Copper from Ore: A Step-by-Step Guide
Heap Leaching. Heap leaching is a method for extracting copper from ore by piling it into an outdoor pile, then sprinkling acid over the heap. The acid reacts with the copper sulfide in the ore and slowly dissolves it away as a solution of sulfuric acid and copper sulfate. This process can take up to several months, depending on the size of …

Extractive Metallurgy of Copper
The most common ore used in copper extraction is Chalcopyrite (CuFeS 2), also recognized as Copper Pyrites and other such sulfides. The proportion of copper in the real ore is too limited for straightforward copper extraction to be feasible. The concentration of ore is required, and the Froth Flotation method is used for this process.

An Introduction to the Chemistry of Metal Extraction
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. Ores are commonly oxides, for example: bauxite (Al 2 O 3) haematite (Fe 2 O 3) rutile (TiO 2). . . or sulfides ...
