The Bingham Canyon mine, is located near Salt Lake City, Utah, US. It is the one of the world's biggest man-made excavation, open-pit copper mines.

The beneficiation of high talc-containing copper–cobalt flotation tailings was studied by centrifugal gravity concentration. It was found that copper and cobalt minerals were finely disseminated in...

Mount Isa Mines operates two separate mining and processing streams, copper and zinc-lead-silver, near Mount Isa, Queensland, Australia.

This study involved the chemical and detailed mineralogical analysis of the final copper concentrate produced at the Lubin Concentrator, one of the concentrating plants of the Mining–Smelting ...

By using real-time plant data from the concentrators in combination with AI-based recommendations from Microsoft's Azure platform, the concentrator operators at ndida will have the ability to adjust operational variables that affect ore processing and grade recovery.

Mineral Processing. As a commonly used process for copper ore beneficiation, flotation can be used for the separation of copper sulfide and oxidized copper ores. The main process of copper ore flotation is rough as follows: ore crushing and screening → stage grinding stage flotation → concentration and dehydration → copper concentrate.

KOLWEZI, DEMOCRATIC REPUBLIC OF CONGO, 24 FEBRUARY 2022 – Kamoa Copper has approved a debottlenecking plan that will increase the combined design processing capacity of the Phase 1 and Phase 2 concentrator plants by approximately 21%, to 9.2 million tonnes of ore per year (Mtpa) from 7.6 Mtpa, once steady-state …

With the addition of the third concentrator, Kamoa-Kakula has become the third-largest copper mining complex in the world, following ndida in Chile and Grasberg in Indonesia.

The stockpiled ore from the Kamoa 1 and Kansoko mines, containing approximately 70,000 tonnes of copper, with the copper price trading at well over $10,000 per tonne, is being used to de-risk the ongoing wet commissioning and ramp-up of the new 5-Mtpa concentrator.

Nifty Copper Operation, located in the north-eastern part of Australia's Pilbara region, is owned by Australia's biggest tin producer, Metals X.

Since inception of the mine, refractory ore from the copper production process was surface stockpiled. KCM has now developed a process to extract copper from the refractory ore stockpile. The company also produces several by-products, including sulphuric acid produced from the smelting process, which is largely consumed in the leaching process.

In developing and utilizing copper ore resources, the classification operation of copper ore concentrator is also an important production link of copper ore separation. With the increasing difficulty of copper mining and sorting, the requirements for screening and classification efficiency are getting higher and higher. Therefore, efficient …

Kamoa Copper's Phase 1, 3.8 Mtpa concentrator plant reached commercial production on 1st July 2021 after achieving a milling rate in excess of 80% of design capacity and recoveries very close to 70% for a continuous, seven-day period.

Copper sulphide ore deposits are of great economic significance for copper extraction. In order to enrich copper sulphides, froth flotation at alkaline pH is typically applied to reject associated gangue minerals, in particular pyrite before the subsequent pyrometallurgical treatment to extract copper from copper sulphides [ 1 ].
