The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger

This is a situation reached in heap bioleaching when air is blown through the base at flows over 6 L/min m 2 (Lizama, 2001). Therefore, Fe +3 was continuously regenerated by bacteria present along the ore

Copper processing - Copper processing - Ores: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature. Occasionally copper is still found in its native form, but more frequently it is mixed with other minerals, some of which may have value

Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of 99.99% pure copper called cathodes, which will ultimately be made into products for everyday use.The most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively,

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 by-product of this process is used for the extraction of oxide ores. Pyroprocessing Sulfide Ores Provides Acid for Leaching

Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is generally limited to rich ores. El Teniente, in Chile, is the world's largest underground copper mine. Open pit mining is

prospecting: In mining, the process of physically searching a region for mineral deposits. pyrometallurgy: The process of extracting and purifying metals from ore using high temperatures. In copper processing, is typically used with copper sulfide ores, and involves froth flotation, thickening, smelting, and electrolysis.

heap leaching: Generally, an industrial mining process in which a valuable metal is extracted from a heap, or pile, of crushed ore. For copper oxide ore, heap leaching is the first stage in the process of hydrometallurgy, in which a chemical solution is applied to a heap of crushed ore, through which it percolates, dissolving the copper.
