The operations consist of fully integrated mining operations and processing facilities, including the Pilar and Vermelhos underground mines and the Surubim open pit mine. Ore is processed using conventional crushing and flotation at the Caraíba Mill, loed adjacent to the Pilar underground mine. A highgrade, clean concentrate grading approximately 35% copper is .
This project considers two open pit copper mines (Highland Valley Copper, BC and Carmen de Andacollo, Chile) and one brownfield project (Quebrada Blanca Phase 2) operated by Teck Resources Limited with the objectives to: i. evaluate the financial impact of "wet mining"; ii. determine and compare the cost of process and makeup water at the plant; and iii. identify .
Background information, formulae and a systematic set of procedures for estimating capital and operating costs for open pit mining equipment are presented in this paper. Firstly, equipment capital costs are required._x000D_ These can be obtained from either suppliers, contractors or from first principles. The equipment is then divided into cost elements. Typically these are fuel .
Nifty was initially discovered by WMC in 1981 and commenced operation in 1993 as an open pit oxide copper mine with processing via heap leaching and solvent extractionelectrowinning ("SX/EW") recovery to produce copper hodes. From 2006, it transitioned to an underground sulphide mine with processing via standard flotation to produce a copper concentrate at rates .
Chile also boasts the world's largest (in terms of output) openpit copper mine, Escondida. The largest copper mine in North America (and the world's largest manmade excavation) is the Bingham Canyon Mine near Salt Lake City, Utah. A billion modernization program completed in 1998 turned Bingham Canyon into North America's lowestcost ...
The second step was to estimate statistical models of capital and operating costs for open pit porphyry copper mines with flotation concentrators. For a sample of 27 proposed porphyry copper projects, capital costs can be estimated from three variables: mineral processing rate, strip ratio, and distance from nearest railroad before mine construction began. Of all the .
Taseko owns of Gibraltar Mines Ltd., which owns 75% of the Gibraltar Joint Venture. On March 31, 2010, Taseko established an unincorporated joint venture ("JV") between Gibraltar Mines Ltd., and Cariboo Copper Corp. ("Cariboo") over the Gibraltar copper and molybdenum mine, whereby Cariboo acquired a 25% interest in the Gibraltar Mine and Taseko retained a .
A Simplified Economic Filter for OpenPit Mining and Heap ... concentration, and heapleaching of copper using commercially available mining cost estimating software and mineral processing models of Camm (1991).
In this paper, in order to achieve a reliable cost model, the technical and economic data of 15 open pit porphyry copper mines have been collected. The proposed cost model is developed based on stepwise multi variate regression. The R square of the presented model was 97. 53% and indied a proper fit on the data set. In addition, the mean ...

For small capacity mines, 40% of the capital cost of the large capacity mine is used based on trends seen in the capital cost calculation for refining. The variable portion of the cost calculation is based on the open pit mining models published by the USGS, which take into account several factors that affect capital expenditures (Camm, 1991 ...
· Large open pit mines are driven by the economies of scale that are achieved at the cost of less selectivity in the discrimination of ore and waste. Planning for these mines is facilitated by the use of block models for mine design, scheduling and the conversion of Mineral Resources into Ore Reserves. This paper reviews various approaches to the estimation of .
