Chapter 6 Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-
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.

Bio heap leaching is used commercially for gold,uranium &copper.The leaching process is based on natural bacteria ability to extract metals from ores. Bioheap leaching is preffered by most of the ...
Acids are introduced to copper-bearing ore, seeping through and dissolving copper and any other metals, including radionuclides. The liquid that "leaches" through the rocks is collected. This liquid contains the dissolved copper, known as a pregnant leach solution (PLS). The copper present in this liquid is collected and later processed.

Heap leaching is a tried and tested mining technique enabling the processing of different kinds of ores which could not otherwise be exploited under viable economic conditions. Modern day heap leaching, which has a relatively low level of energy consumption, is for example
Ores near the surface can be quarried after removal of the surface layers. The ore is treated with dilute sulfuric acid. This trickles slowly through the ore dissolving copper to form copper sulfate. The copper is recovered by electrolytic refining. Advantages of this process are: See for further information on the leaching process.

Nov 07, 2018· In ore beneficiation, flotation is a process in which valuable minerals are separated Water quality, flotation equipment size and type, temperature, and ore body variation are Gold, silver, copper, lead, zinc, molybdenum, iron, potash, phosphate, and even Oxide copper minerals are very soluble in the leach solution.
The process involves leaching under controlled intensive cyanidation conditions followed by ... an otherwise gold free copper ore. The remaining process steps are shown for a typical flowsheet in figure 1. FIGURE 1 Typical Process Flowsheet The gravity concentrate is leached in the InLine Leach
Extraction of copper from suitable ore by leaching methods is generally assumed to cost less than the combined expense of concentration, smelting, and refining, and experimental data tend to confirm this opinion. At the Butte-Duluth plant, which is handling in excess of 100 tons of oxidized ore daily, the copper is said to cost $0.085 per pound.
In situ biomining does away with the ore mining process altogether; acidified leach liquor is pumped directly into the ground and the copper is solubilized utilizing preexisting bacteria in the ore deposits. The copper-rich liquor is extracted from wells dug beneath the deposits (Rawlings 2002).
Heap Leaching: A Growing Technology in Beneficiation; Heap Leaching: A Growing Technology in Beneficiation. This article was co-authored by: ... leaching has also gained increased attention as a result of its demonstrated success in being combined with the SX-EW process, most notably in the copper industry.
The support rock itself may be a low-grade copper ore. The ratio of support rock to concentrate is in the range of 5:1 to 10:1 by weight. The heap is inoculated with thermophilic bacteria and a process leach solution consisting of sulfuric acid, ferric iron and nutrients is applied to the heap.
