Mining history of Cyprus Copper mines Euromines
The only mining activity that exists today in Cyprus is the copper mine of Skouriotissa which produces, since 1996, copper metal hodes (99.999%) applying the Acidic Leaching – Solvent Extraction Electrowinning method (Leaching SX EW). The mining history of Cyprus has connected the name Cyprus, with the name of copper (Cuprous).

Types of Extraction Scool, the revision website
Methods of extraction Many metals are found in the Earth''s crust as ores. An ore is usually a compound of the metal mixed with impurities. When the metal is dug up, a method must be used to separate the metal from the rest of the ore. This is called extracting the metal. The method of extraction depends on how reactive the metal is. The more reactive the metal, the more difficult it is to

Why is the extraction of copper from pyrites more
The Gibbs free energy of formation (Δ f G) of Cu 2 S is less than that of H 2 S and CS 2.Therefore, H 2 and C cannot reduce Cu 2 S to Cu.. On the other hand, the Gibbs free energy of formation of Cu 2 O is greater than that of CO. Hence, C can reduce Cu 2 O to Cu.. C (s) +Cu 2 O (s) → 2Cu (s) + CO (g). Hence, the extraction of copper from its pyrite ore is difficult than from its oxide ore
