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.
Copper Ore Processing Methods. Previous Next ... production of concentrates other than copper concentrates from plants essentially copper plants—for example, the production of pyrite concentrates by the Britannia Mining Co., the production of zinc concentrates at the Flin Flon and Sherritt Gordon plants, and the production of nickel-copper ...
Gold Processing,Extraction,Smelting Plant Design ... 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. During this process, the silver & copper can also be collected.
Sometimes gold is present as a minor constituent in a base metal (e.g. copper) concentrate, and is recovered as a by-product during production of the base metal. For example, it can be recovered in the anode slime during the electrorefining process.
The treatment of these products depends on the metallurgical extractive process of lead and copper. Gold Smelting Equipment It has been shown that concentrates obtained by gravity devices and cathodes can be smelted directly most the time. Silver-gold concentrates can be smelted too.
Northparkes Mines is a copper-gold mine near the remote Australian town of Goonumbla, about 27km north-north-west of Parkes, a regional centre in central-west New South Wales. The project is a joint venture between Rio Tinto (80%) and Japanese multinational Sumitomo Group (20%).
Additionally, today's mining equipment makes it possible to reduce waste and decrease chemical exposure during all phases of the copper mining process. The Basics of Copper Mining and Processing. Mined from open pits, copper ore must be crushed as part of the process that occurs between extraction and production.
The PLATSOL ® process may also offer a non-cyanide process treatment option for recovery of copper and gold from copper–gold and gold–copper concentrates. Ferron et al. reported on batch laboratory testing of a copper–gold concentrate and a refractory gold–silver concentrate under PLATSOL ® .

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, due to the different ...
Patented process in use at Saudi Arabia mine and in Chile Flotation froth of copper concentrate during laboratory testing in Santiago, Chile Barrick has developed and patented a new flotation process that can produce copper concentrates from copper or copper-gold ores using salt or brackish water. The new process, an air-metabisulfite treatment, does not require lime or cyanide.

Figure 1 - CESL Flowsheet for Processing Hg-rich Copper Concentrates Copper and mercury results at the continuous pilot scale confirmed those obtained in batch testing. Gold recovery from the pilot leach residue was also assessed with elemental sulphur flotation of the residue
Copper Refining: From Ore to Market. ... copper concentrate is dried before being heated in a furnace. Chemical reactions that occur during the heating process cause the concentrate .
grade copper-gold ores from open pit and underground sources in two parallel processing trains. The copper flotation circuits upgrade copper content by a factor of 80-160 times from feed to a saleable copper concentrate containing approximately 50% of the contained gold in feed (remaining gold .
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 ...
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. 12.3.2 Process Description2-4
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 ...
Copper processing - Copper processing - Roasting, smelting, and converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of either the hearth or ...
The more gold, the faster the process. This is because it is the friction of gold against gold which facilitates the cleaning process. Once the gold is glittery, rinse the soapy water out of the jar, pour the gold into a small (metal) finishing pan, and heat it up (outside and down wind) until the gold takes on a deep, natural, shiny luster.
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.
