The Extraction of Copper
Extracting copper from its ores. The method used to extract copper from its ores depends on the nature of the ore. Sulfide ores such as chalcopyrite ((CuFeS_2)) are converted to copper by a different method from silicate, carbonate or sulfate ores. Chalcopyrite (also known as copper pyrites) and similar sulfide ores are the commonest ores of ...

Extraction Of Iron | PPT
Ore: A mineral from which metals can be extracted profitably is called a metal ore. Profitable extraction means that the cost of getting the metal out of the ore is sufficiently less than the amount of money made by selling the metal. So All Ores Are Minerals But All Minerals Are Not Ores. The most common metal ores are oxides and sulphides.

Notes OCCURRENCE AND EXTRACTION OF METALS
16.2 GENERAL PRINCIPLES OF EXTRACTION OF METALS The process of extracting the metals from their ores and refining them is called metallurgy . The choice of the process depends upon the nature of the ore and the type of the metal. The metal content in the ore can vary depending upon the impurities present and chemical composition of the ore.

On the other hand, carbonated metal ores are heated in a vaccum for easy extraction of metals. This is called calcination. This is how a concentrated ore is again refined to gather purer metals. This is a gist of how the extraction of metals ores and minerals is performed based on the physical and chemical properties of the impure ores.

The hydrated metal-ion is stripped of the water molecules and form complexes with the active component in the organic phase. Thus, the metal-ion is transferred from the aqueous phase to the organic phase. The metal ion can then be stripped from its complex (in the organic phase) using an inorganic acid or aqueous salts or bases (Luo et al., 2006).
