28% reduction in production costs per tonne at a remote, open-cut copper mine. CONTEXT. Our client, one of the largest copper mines in Africa, was a high unit cost, low recovery and low productivity asset across almost all benchmarks. As a consequence of a prolonged period of depressed metal prices, the asset was placed in partial care and ...

Conversely, when a mining company reports a drill result of 10 grams per tonne, you now know that this equals (10 x 0.029 =) 0.29 ounces per tonne. On the break even analysis page, I also explained how you can convert a drill result reported in a percentage (%) to an amount in pounds (lbs) per tonne.

C1 cash costs have been reduced to US$1.42/lb in 2014 from US$1.48/lb in 2013 and US$2.08/lb in 2012 returning costs to the second quartile in the industry. Over the same three years production has gone from 282kt to 470kt in 2014. In September 2015, Collahuasi decided it would cut production by 30,000 tpy due to lower copper prices.

Effective costs of Copper Processing Example of porphyry copper mine processing costs Assuming a freight cost of £ 20/ton of concentrate, The total deduction are £ (0.61 + 0.56 + 0.41) = £ 1.58 The NSR per tonne of ore treated is ...
Copper - From Beginning to End. Copper is a major metal and an essential element used by man. It is found in ore deposits around the world. It is also the oldest metal known to man and was first discovered and used about 10,000 years ago. And as alloyed in bronze (copper-tin alloy) about 3000 BC, was the first engineering material known to man.
Reserves. Copper is a fairly common element, with an estimated concentration of 50–70 ppm (0.005–0.007 percent) in earth's crust (1 kg of copper per 15–20 tons of crustal rock). A concentration of 60 ppm would multiply out to 1.66 quadrillion tonnes over the 2.77e22 kg mass of the crust, or over 90 million years' worth at the 2013 production rate of 18.3 MT per year.
Oct 01, 2020· The 19-Mtpa scenario shows the potential for average annual production of 501,000 tonnes of copper at a total cash cost of US$1.07/lb. copper during the first 10 years of operations and production of 805,000 tonnes of copper by year 8. At this future production rate, Kamoa-Kakula would rank as the world's second largest copper mine. Figure 1.

More examples of our world-leading copper expertise include: Phu Kham Project (Pan Australian Resources Limited) in Laos - Includes a 35.000 t/d copper-gold concentrator and associated infrastructure. The project was delivered on budget, with over 3 million manhours LTI free, and has set a world benchmark as the lowest cost per tonne concentrator.
Mining Cost Service continues to be a useful reference on a wide range of topics for early stage mine planning through to 'fill the gaps' on more detailed studies. Mining Cost Service provides an independent source for information on equipment, quantities and cost for a significant number of mining methods and range of production rates.
WORLD COPPER NET CASH COST C3 CURVES 2000 VS 2017(F) • Costs moved from the second to the fourth quartile. • In 2000, the production of Chile represented 34.7% of the world copper mine production. In 2017 it represented 26.3% (august). Source: Cochilco and Woodmackenzie Q32017
Copper futures traded above $3.1 per pound, remaining close to the levels not seen since June 2018, supported by optimism surrounding a coronavirus vaccine, growing demand from top consumer China and a decline in Chile's production. Upbeat Chinese trade figures showed copper imports rose more than 40% year-on-year in January-October, beating the previous record for the country's annual ...
