Figure 1 CESL Flowsheet for Processing Hgrich 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
Gold Ore Processing: Project Development and Operations, Second Edition, brings together all the technical aspects relevant to modern gold ore processing, offering a practical perspective that is vital to the successful and responsible development, operation, and closure of any gold ore processing completely updated edition features coverage of established, newly implemented ...
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 nickelcopper ...
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, refractorylined furnace of either the hearth or ...
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 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 .
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. Silvergold concentrates can be smelted too.

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.
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, due to the different ...
This process is believed to be adaptable to the recovery of gold (and silver) from copper leach residues containing sulfur and may well open a new route for combined copper and goldprocessing options for copper concentrate producers. More details on this process may be found in Chapters 28 and 50 Chapter 28 Chapter 50. 2.
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 ...
CESL COPPER PROCESS – AN ECONOMIC ALTERNATIVE TO SMELTING Glenn Barr, Jennifer Defreyne, Keith Mayhew CESL Engineering ABSTRACT Cominco Engineering Services Ltd (CESL), a subsidiary of Teck Cominco Metals Ltd, has developed proprietary hydrometallurgical processes for the treatment of nickel, copper and coppergold concentrates.

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
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.

grade coppergold ores from open pit and underground sources in two parallel processing trains. The copper flotation circuits upgrade copper content by a factor of 80160 times from feed to a saleable copper concentrate containing approximately 50% of the contained gold in feed (remaining gold .
The concentrate is a finely milled, dark gray material containing about 30 % copper (Cu), 30 % iron (Fe) and 30 % sulfur (S). The concentrate also often contains small amounts of precious metals and a range of other elements, which we process in the smelters.
We produce copper, lead, nickel and zinc concentrates. The biggest source of raw materials for our smelters is metal concentrates. We also use certain intermediate forms and secondary materials. We purchase some of the raw materials from mines with which we have agreements.
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.
One prevalent form of copper concentrate contains gold and silver, like the one produced by Bougainville Copper Limited from the Panguna mine from the early 1970s to the late 1980s. The typical contract for a miner is denominated against the London Metal Exchange price, minus the TCRCs and any applicable penalties or credits.
