The Canadian Copper Refinery (CCR), part of the Glencore group, is a world-class, modern and competitive copper and precious metals refinery. It is in its facilities in Montreal East, the only ones of its kind in North America, that we give precious metals all their nobility, copper their purity, and other metals their specific characteristics.

The step by step copper refining process: Extraction of copper from ore begins with pre-treatment. Due to the decreasing concentration of copper in ores, this is an important step to decrease the volume of material and to increase the grade of copper in the ore. Most copper ores will only contain a small percentage of copper mineral, with the ...

Currently, it operates a 400,000 Metric Tonnes Per Annum (MTPA) Copper Smelter with associated facilities such as a Refinery and Copper Rod Plant, a Sulphuric Acid plant of more than 12,00,000 MTPA and a Phosphoric Acid plant of 220,000 MTPA at Thoothukudi, Tamil Nadu. Sterlite Copper also operates a 160 MW coal based power plant in …

William G. Davenport, in Extractive Metallurgy of Copper (Fifth Edition), 2011. Publisher Summary. This chapter highlights that electrolytic refining is the principal method of mass producing high-purity copper. Copper from electrorefining, after melting and casting, contains less than 20 ppm impurities, plus oxygen which is controlled at 0.018 ...

Smelting of low-grade copper scrap begins with melting in either a blast or a rotary furnace, resulting in slag and impure copper. If a blast furnace is used, this copper is charged to a converter, where the purity is increased to about 80 to 90 percent, and then to a reverberatory furnace, where copper of about 99 percent purity is achieved.

The AMES Copper Group process is considered a secondary copper refinery and consists of a pyrometallurgical process to transform scrap copper into copper anodes with over 99.7% pure copper. Secondary sources include scrap generated internally, new scrap from metal fabricators, and old scrap from consumer products.

In the Głogów Copper Smelter and Refinery, copper concentrate is smelted using flash furnace technology. This facility also includes a Precious Metals Plant that produces silver and gold.
