Copper is a mineral that was used thousands of years ago by ancient civilizations, and is still being used today. Copper can be extracted cheaply and its properties and uses make it valuable as a commodity. Copper ore can be found close to the earth's surface, as well as in deepsea pockets.
Firerefined copper is adequate for noncritical applications such as water tubing, bar stock, or ingots for alloying. Copper intended for electrical uses, however, is produced by electrorefining or sometimes electrowinning techniques. Electrorefining process Virtually all copper produced from ore receives an electrolytic treatment at some stage
Impurities have to be removed. Copper is purified by electrolysis. In this process copper is transferred from an impure anode to the cathode of an electrolytic cell. The insoluble impurities fall to the bottom. The copper produced by this process is % pure copper. This is similar to the electrolysis that is done in a school lab.
The Outotec Precious Metals Plant is based on over 30 years of experience in anode slime treatment. The recovery and refining processes are highly automated, offering a safe working environment and zero toxic gas emissions. Enables high recovery of valuable metals ; Ensures highquality products (>% for gold and silver)
The copper ore is crushed into 250mm pieces, and carried through a tunnel on a 5 mile conveyor belt. This is done so that the segments will be smaller, and therefore more able to float in the next process. At this point the ore is made up of approximately % of copper . 2. Froth Flotation
Types of ore; There are two distinct types of copper deposits: sulfide ore and oxide ore. Currently, the most common source of copper ore is the sulfide ore mineral chalcopyrite, which accounts ...
Molybdenum produced as a byproduct of copper from copper porphyry deposits, like the Bingham Canyon deposit in Utah, is removed as molybdenum disulfate during flotation of the powder copper ore. The concentrate is roasted to make molybdic oxide, which can be put through the same sublimation process to produce molybdenum metal.
Dec 18, 2016· Silver Mining Process . Silver is mined using a number of processes. One of the most common processes of extracting silver metal for the ore is the heap leach or cyanide process. The process is most popular with many miners because it is low .

Roll over diagram of sequence, The flow chart shows you how copper is extracted from its ore and converted into pure metal. Roll over each stage . The ore is enriched using a process called froth flotation.
Copper is found alongside many other types of ore. It can be found near gold, silver, zinc, lead, and other types of metal deposits. When mixed in with other ores, copper is not usually found in great abundance. Until the development of the modern copper mining process, it was .

How to Invest in Copper Stocks Digging into the copper mining industry can reveal some potential investment opportunities and better explain what it takes to make money from an ore that is growing ...
Mixed copper ores are treated through different processes depending on the degree of oxidation as well as the consumption of acid. With the availability of realtime technology that can reliably measure differences between oxide and sulphide minerals, it is now possible to control a mixed copper ore process.
