Mining Cost Service contains the results of our annual surveys of and Canadian copper, lead, zinc, nickel and molybdenum smelters. Included where available are the current and projected availability of furnace capacity, the types of material accepted, deleterious element limits, metals recovered, and indications of the company's interest in obtaining additional concentrates.
The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore. Read More
Even the best chemical method cannot remove all the impurities from the copper, but with electrolytic refining it is possible to produce % pure copper (whatever method is used to manufacture copper from its ore, its final purification is by electrolysis). Process for the Electrolytic Refining of Copper Raw material: Blister Copper
The scraps containing precious metals are fed as the raw materials into the copper smelting process, together with ore concentrates. The resulting crude copper contains the precious metals. This crude copper is cast into an anode and refined by electrolysis in an aqueous solution to obtain electrolytic Cu.
The copper ore usually contains a large amount of dirt, clay, and a variety of noncopper bearing minerals. ... 11 After refining, the copper cathodes are melted and cast into ingots, cakes, billets, or rods depending on the final application. ... The current trends in copper processing are towards methods and equipment that use less energy and ...
Nickel processing Nickel processing Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of highertemperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel ...
In general, gravity separation is directly adopted to recycle this kind of gold. The gold ore refining equipment required is relatively simple, like chutes. However, for some gold ore with very small fineness, chemical dressing method like cyaniding and leaching is essential. And this method requires more gold ore refining equipment.
The above flowsheet shows a basic copper mine process, from mine to metal. There are two distinct types of copper ore, the sulfide ore and the oxide ore. ... etc. that are used in every day life. Below are some photos of the process equipment at an Arizona Copper Mine. Copper Ore being loaded into a 300 ton truck for transport to the crusher.

a process providing for the pyrometallurgical recovery of copper from copperbearing material and isolation of lead/tin, nickel and zinc in economically recoverable form. copperbearing material is initially melted and reduced with solid material containing metallic iron to form a black copper which is refined by blowing with oxygen to oxidize metallic impurities and produce anodegrade copper.

Smelting is a process of applying heat to ore in order to extract a base is a form of extractive is used to extract many metals from their ores, including silver, iron, copper, and other base uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.
For extracting gold from lowgrade ores, heap leaching is practiced; huge heaps are sprayed with a dilute solution of sodium cyanide, and this percolates down through the piled ore, dissolving the gold. There are very well defined rules for the safe and responsible use of cyanide – as laid out in the International Cyanide Code. Gold refining
Gold refining is a process that involves recovering gold metal from gold ore and converting it to pure gold, free from impurities. There are several refining systems used to make gold bars. Electrolyte process, chemical treatment, smelting and cupellation are some of the common refining .
Copper minerals and ores are found in both igneous and sedimentary rocks. 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.
