of a copper concentrate processing facility. Potential developers could include the producers of concentrate and operators of concentrate processing facilities in other states. Nevada is a miningfriendly jurisdiction, and potential locations for a copper concentrate processing facility were identified with access to transportation, energy, and air
Today, flotation is commonly used in the processing of primary copper–gold ores to produce a copper concentrate containing gold as a coproduct, where the gold is recovered as a byproduct of copper smelting and refining (La Brooy, 1992). The gold is usually discrete and either free, associated with copper sulfides or associated with iron ...
THE NEW CESL GOLD PROCESS By Glenn Barr, Willy Grieve, David Jones, and Keith Mayhew Cominco Engineering Services Ltd. Presented by ... Gold and Silver Recovered in the Copper Smelting Process When copper concentrates are processed by smelting and refining, the precious metals are generally recovered in high yield (about 90 98%).
Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and ends with sheets of % pure copper called cathodes, which will ultimately be made into products for everyday most common types of ore, copper oxide and copper sulfide, undergo two different processes, hydrometallurgy and pyrometallurgy, respectively, .
Sulphide ore is treated in the processing plant producing a coppergold concentrate. The plant currently produces approximately 15,000 tonnes of concentrate per month at a grade of % copper with credits received for gold in the concentrate.

The flotation concentrates can be sold to the smelting factory based on normal trade or processing agreement. The flotation concentrates go to cyanide process or calcination process (if there is arsenic together with the concentrate) and further process to get pure gold in the smelting factory.
Copper is produced in the U. S. primarily by pyrometallurgical smelting methods. Pyrometallurgical techniques use heat to separate copper from copper sulfide ore concentrates. Process steps include mining, concentration, roasting, smelting, converting, and finally fire and electrolytic refining. Process Description24
Copper ores containing chalcopyrite can be concentrated to produce a concentrate with between 20% and 30% copperinconcentrate (usually 27–29% copper); the remainder of the concentrate is iron and sulfur in the chalcopyrite, and unwanted impurities such as silicate gangue minerals or other sulfide minerals, typically minor amounts of pyrite ...
Copper concentrate is the first commercial product of the copper production line and is composed of approximately equal parts of copper, iron and sulfide. Concentrates are the raw material for all copper smelters, which by processing it obtain an impure form of metallic copper, anode or blister copper, which is later used to produce high purity ...
Can someone explain the process of extracting gold once you have obtained a concentrate after putting your alluvial material through a gravity machine. We put about 200kg of soil through a gravity machine and ended up with about 2kg of concentrate. We then took this to a lab to see what the gold con
process of those concentrate all gold and silver are practically in the blister copper, which is cast into anodes. Those copper anodes are electrorefined in an electrolytic system, where the electrolyte is an acid copper sulphate solution, where a high purity electrolytic copper is produced (>999,9/1000).
Gold processing Gold processing Mining and concentrating: The nature of the ore deposit determines the mining and mineral processing techniques applied. Oxide ore deposits are frequently of such low grade (, 3 to 10 parts per million) that extensive mineral processing cannot economically be justified. In this case they are merely shattered by explosives and then piled into heaps for ...
Cyanidation carbon adsorption process is the most widely used in gold cyanide extraction process . The principle in brief is the carbon could adsorb liquid gold from cyanide solution . In 1970s, with the research and establishment of adsorption of carbon loaded with gold and the recovery of carbon discharge gold, make recycle the carbon and reduce the cost, and easy to process the gold ...
for its minerals. It is important to note that our gold/copper/silver concentrates are already a highly processed and beneficiated product. Whilst the smelters do charge to process our concentrate, on average for the contract terms that we have agreed with the overseas smelters, we receive 97% of the total value of gold, silver and copper.
The copper concentrate and flux melt, and collect in the bottom of the furnace. Much of the iron in the concentrate chemically combines with the flux to form a slag, which is skimmed off the surface of the molten material. ... Gold, silver, and other precious metals are also important byproducts. ... The current trends in copper processing are ...

Sometimes gold is present as a minor constituent in a base metal ( copper) concentrate, and is recovered as a byproduct during production of the base metal. For example, it can be recovered in the anode slime during the electrorefining process.
