Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important byproduct of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching
Escondida copper, gold and silver production. Production at the mine was cut back during the period 2003 on account of the weak world market conditions for copper. The partners in the project decided to mine lowergrade ores while maintaining the concentrator throughput, thus reducing the impact on pertontreated costs.
The flowsheet discussed in this study is for treatment of 100 tons per day oxidesulfide copper ore by the leaching process using sulfuric acidferric sulfate solvent. This flowsheet would also be suitable for a larger tonnage by proper sizing of the various units of equipment.

Since it burst onto the world''s metallurgical scene in the late 1960s, copper SX/EW has gone from strength to strength and has seemingly blitzed all comers. But it does have some drawbacks ...
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either openpit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted.
Copper does not react with water, but it does slowly react with atmospheric oxygen to form a layer of brownblack copper oxide which, unlike the rust that forms on iron in moist air, protects the underlying metal from further corrosion (passivation).

Subsequent steps depend on the nature of the ore containing the copper and what will be extracted. For oxide ores, a hydrometallurgical liberation process is normally undertaken, which uses the soluble nature of the ore minerals to the advantage of the metallurgical treatment plant.
Cobalt processing: Cobalt processing, preparation of the metal for use in various products. Below 417 °C (783 °F), cobalt (Co) has a stable hexagonal closepacked crystal structure. At higher temperatures up to the melting point of 1,495 °C (2,723 °F), the stable form is facecentred cubic. The metal has 12

We shall begin by looking at the mining and processing of the copper bearing ore, followed by an examination of an established and a modern copper smelting process. Mining for Copper Bearing Ore. There are two categories of copper ore; sulphide ore which is processed to enrich it before smelting, and oxide ore that is subjected to acid treatment.
