Oxidized zones are found in many deposits, frequently found in arid areas of the world including the United States, Mexico, Peru, Chile and Africa. The oxidized zone of mineral deposits found in the Arizona and New Mexico are around 122 metres or 400 feet deep. Cyprus is the island, which gave its name to the metal.
Copper can be found in more than 200 minerals, but only about 10% of this occurs in the form of sulphide minerals or oxidized minerals , which are of significance as copper ores . Depending mainly on the ore type, as well as the geographical, economic and environmental ...
Ore Deposits Formed by Oxidation and Supergene Enrichment. When ore deposits are exposed to the oxidation zone they are weathered and altered with the country rocks. The surface waters oxidize many ore minerals and yield solvents that dissolve other minerals. An orebody thus becomes oxidized and generally leached of many of its valuable ...
The oxidation of sulfide ores by ozone can occur by dissolution of sulfide species and the formation sulfate ion, as suggested by Elorza et al. Then, the global reaction of the pyrite oxidation in the presence of ozone can be described as follows: FeS2 + 2/3O 3 + 5/2O 2 + H 2O = Fe 2+ + 2SO 42 + 2H +
