The copper stream became part of Xstrata Copper and the lead-zinc-silver stream became part of Xstrata Zinc. [53] As production from the aging Mount Isa lead-zinc underground mine declined, MIM recommenced mining in the Black Star open cut, the site of some of MIM's earliest mining operations, in October 2004, aiming to maintain feed to the lead–zinc concentrator.

Mining and Extraction: Oxide Ores

Copper is refined from ores in the ground, either through underground or open-pit mines. Most of the copper ores mined today are oxide or sulfide ores. Extraction of sulfide ores is covered in more detail in Copper Mining and Extraction: Sulfide Ores (11–14), but is introduced here because an important by-product of this process is used for the extraction of oxide ores.

Xstrata Canada Corporation is a privately held company in Toronto, ON and is a Headquarters business. Categorized under Copper Ores. Current estimates show this company has an annual revenue of 3264591680 and employs a staff of approximately 13500.

In 2010 it was estimated that the project would deliver 2.9 billion tonnes at 0.51% copper and 0.2g/t gold (at a 0.2% copper cut-off). Based on these ore reserves, the company targets to complete the mining of 15-million tonnes of copper and 17.6-million ounces of gold; an estimate of 375,000 tonnes of copper and 360,000 ounces of gold per annum, over a 17-year period.

Africa Copper Boosts Glencore Xstrata

Top miner Glencore Xstrata plc has met market forecasts with a Q1 2014 copper production increase of 24% year-on-year, driven primarily by output expansion in Africa and increasing ore grades in South America. Among diversified miners, Glencore enjoys the

Xstrata plc was an Anglo-Swiss multinational mining company headquartered in Zug, Switzerland and with its registered office in London, United Kingdom. It was a major producer of coal (and the world's largest exporter of thermal coal), copper, nickel, primary vanadium and zinc and the world's largest producer of ferrochrome.

Xstrata Copper Canada permanently ceased operation of its copper and zinc metallurgical plants in May 2010. Located about an hour's drive from Timmins,Ontario, the Kidd metallurgical site — Kidd Met for short — processed ore from the massive Kidd copper and zinc mine a few miles away. While the Kidd mine continues to operate, smelting activity was moved to the company's other

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

According to infomine, the deposit is one of the largest copper-zinc ore bodies in the world. "We boarded the bus in Lima at 9 on Monday night and arrived at 7 on Tuesday morning – from sea level to 4,300 meters in 10 hours," recalled Ricardo, MineSight Peru branch manager.

Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9% purity. Copper can be recycled indefinitely without the base metal being compromised

Xstrata

Xstrata operates the Mount Isa Mines lease adjacent to the town, which comprises the Enterprise underground copper mine, X41 underground copper mine, Black Star Open Cut silver-lead zinc mine. Silver-lead-zinc ore is also mined 20 km to the north at Hilton from the George Fisher underground mine, and the adjoining Handlebar Hill open cut, which is trucked back to Mount Isa for processing.

Copper Refineries Ltd (CRL), now owned by Xstrata, recently completed an expansion and upgrade of the tankhouse facilities at their Townsville plant in Australia. The main objective of the project was to upgrade an existing product weighing, loading and despatch (PWLD) operation and to improve and raise the level of automation throughout the plant.

Copper ore is processed at the on-site concentrator and trucked to Mount Isa Mines for smelting into copper anode. NEW SOUTH WALES With a mining history spanning over 140 years, our CSA Mine is Australia's highest grade copper mine, and at 1,600 metres deep, it is also the second deepest underground copper mine in the country.

The overland conveyor at Antapaccay will transport copper ore over a distance of some 6.5 km from the mine to the processing plant. The belt will be 1,372 mm wide, travel at 6.2 m/s, and is designed to transport about 5,260 t/h of material.
