Copper North's key asset is the Carmacks Copper Project, located in the Yukon Territory, Canada. Carmacks is permitted for construction and will produce 30 million pounds of cathode copper per year. The project is being re-engineered as a copper-gold-silver leach operation. A Preliminary Economic Assessment was completed in May 2014 and indicates that the addition of gold and silver recovery ...
Sulfide ores. Secondary sulfides – those formed by supergene secondary enrichment – are resistant to sulfuric leaching. These ores are a mixture of copper carbonate, sulfate, phosphate, and oxide minerals and secondary sulfide minerals, dominantly chalcocite but other minerals such as digenite can be important in some deposits.
Innovations: Introduction to Copper: Mining & Extraction. Mining of copper ores is carried out using one of two methods. It is used to make sulfuric acid, which is sold or used to leach copper from suitable ores . with safe modern explosives and the use of heavy-duty mechanical cutting equipment,

CESL copper leach plant are lower compared to other competing hydrometallurgical leaching and refining technologies and the implementation risk is less due to its thorough development. The process has the additional benefit of reducing shipping costs for concentrate producers that
Copper processing, the extraction of copper from its ores and the preparation of copper metal or chemical compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society. The pure metal has a face-centred cubic crystal structure, and
Leaching is a chemical process in mining for extracting valuable minerals from ore. Leaching also takes place in nature, where the rocks are dissolved by water. Post leaching, the rocks are left with a smaller proportion of minerals than they originally contained. The leaching process in mining is
In 2001, bioleaching constituted approximately 10% of Chilean copper production and heap and dump leaching, in general, constituted approximately 30% of Chilean production. 2 The first Chilean plant to be put into operation was S.M. Pudahuel.
Heap leaching is a tried and tested mining technique enabling the processing of different kinds of ores which could not otherwise be exploited under viable economic conditions. Modern day heap leaching, which has a relatively low level of energy consumption, is for example successfully used for the beneficiation of certain types of gold ores in Turkey . It contributes to the substantial ...

Safely recovering precious resources - With over 100 major mining projects in more than 34 countries, Ausenco has extensive knowledge and experience in leach pad engineering - particularly for gold and copper.
First stage sulphuric acid leach followed by solvent extraction/electrowinning for recovery of copper. Second stage cyanide leach of rinsed/neutralized slurry for gold and silver recovery by Carbon-in-Leach (CIL). Barren slurry treated for cyanide destruction and filtered for final dry stack placement (PEA November 25, 2016)
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.
Mining: Copper can be extracted from its ore by: 1. Traditional mining. underground : sinking a vertical shaft into the Earth to an appropriate depth and driving horizontal tunnels into the ore. open pit: 90% of ore is mined by this method. Ores near the surface can be quarried after removal of the surface layers. 2. Leaching. The ore is treated with dilute sulphuric acid. This trickles slowly ...
