Globally benchmarked integrated design. Palabora Mining Company operates a successful underground blockcave mine, producing 80,000 tonnes of copper ore per annum. Palabora's blockcave mine is a benchmark for integrated design. No other blockcave mine has been put into as competent an orebody.
amount of mine energy per ton of cathode copper also increases. Similarly, as the pit depth below the surface rim increases, the vertical and horizontal distances that the waste rock and ore must be hauled also increases. This increase is reflected in greater energy use, primarily for hauling. Much of the energy consumed in conventional
Worldwide mining operations are as much as 28 percent less productive today than a decade ago, according to new McKinsey research. The results from McKinseys new MineLens Productivity Index (MPI), which adjusts for declining ore grades and mine cost inflation, show that the pronounced decline in productivity is evident across different commodities and is seen in most mining players and

Radomiro Tomic was built in 1998 at a cost of US$641 million for a design plant capacity of 150,000 metric tons of copper per year. Capital costs at this level of operation were to be US$0.08/lb of copper and operating costs, as shown in Table 2, were estimated at US$0.34/lb of copper.

ore than the net tonnage of copper in the ore.5 A tonne of lean ore requires no more capital, energy, labor, and supplies to mine than a tonne of rich ore. However, because the rich ore contains more copper, it requires less of these inputs per tonne of copper recovered. The gross tonnage basis for costs is particularly important in

short time frame. Capital costs, on a comparative basis for the restored production capacity, are very low. On an annual basis the operation becomes cash neutral in year four and cash positive in year eight. Operating and capital costs, per pound of copper, during the project are summarized as follows Phases 13 Phase 4 Onward Life of Project
Figure 1 is a generalized diagram of a conventional copper flotation plant from the point where ore first enters the circuit to the production of concentrate and tailings. To prepare ore for the flotation process, runofmine ore, which may contain from about 2 to 5 percent water, by weight, when mined, is
Mining at Aitik started on the basis of a 50t reserve, but by 1998 the mine had yielded 300t of ore. As of November 2009, ore reserves were 747t grading at 0.25% of copper, 0.14g per tonne of gold, 1.7g per tonne silver, and 29g per tonne molybdenum. Proven and probable ore reserves amount to 518t and 229t, respectively.
Minera Lumina Caserones Copper Project. The Caserones copper mine project was completed in 2013. At peak, construction employed approximately 7,000 local workers. The mine is expected to process around 105,000 tons per day of primary and secondary copper ore to meet increasing demand, particularly in the Asian market.
The three mines produced 420.4kt of copper, 44.304 Moz silver, and 82.8koz gold in 2014 from the Kupferschiefer ore which makes it the fourth largest copper mining operation worldwide and the

Two main types of mines Open pit mining Roughly ten times lower in cost per ton compared to under ground mining Slope stability decide waste/ore ratio With low grades a high production rate is needed Big equipment for high volume production Under ground mining Under ground mines commonly have lower production rate Increased cost to infrastructure and ground support
This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western U.S. mining operations. All costs listed are in 2012 US$. The key design criteria

This article presents cost models for open pit mines, which takes into account cost uncertainty. In this paper, cost uncertainty is considered as cost of under production, and cost of over production.
As a simplified example, if 20 kWh are required to crush and grind a ton of ore grading 0.5 percent copper, the amount of electricity required to recover one ton of copper is about 4,500 kWh, based on an overall copper recovery of 88 percent.
More examples of our worldleading copper expertise include Phu Kham Project (Pan Australian Resources Limited) in Laos Includes a 35.000 t/d coppergold 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.
Similar to most mining plants, the production process of company A consists of two major components, the open pit mine and the copper ore enrichment plant. An open pit mine is an excavation or graze made into the surface of the ground for the purpose of extracting ore, also known as opencast mining or opencut mining.
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 (coppertin alloy) about 3000 BC, was the first engineering material known to man.
