Jun 23, 2013 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 thus As mining, milling, and other costs must be deducted from thisfigure, it is apparent that this mine with very low operatingcosts can have any hope of profiting from such low-gradeoperations. Assuming a typical large open-pit mining costs of 1.25/ton

Jun 07, 2021 Converting: Finally, matte copper is converted into a copper-rich slag, which is then returned to the leaching process and separated from “blister copper, which is sent to another furnace for casting. Waste Generation. Copper mining wastes make up the largest percentage of metal mining and processing wastes generated in the United States

SX EW Capital & Operating Cost of Solvent Extraction

SX EW Capital & Operating Cost of Solvent Extraction

Apr 27, 2017 Solution mining followed by solvent extraction-electrowinning (SX-EW) is one possible way to economically extract copper from ore bodies which cannot otherwise be profitably exploited. Published costs for the unit processes of SX and EW are out of date especially in view of the newer reagents now available and the newer circuit configurations

Chapter 6 Copper Production Technology

grade ores and continually reduce the costs of production. Economies of scale have been real-ized in all phases of copper production. Both ma-chine and human productivity have increased dramatically. This chapter briefly describes the technology for producing copper, from exploration, through mining and milling, to smelting and refining or

Opening New Mines

Opening New Mines

The calculation assumes that this cost is divided evenly into mining and refining, so the constant capital cost of mining becomes USD 200 million. 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

Copper - Rio Tinto

Copper - Rio Tinto

Our very first mine was a copper mine on the banks of the Rio Tinto river, in Andalusia, Spain – bought in 1873 by a British-European investor group led by Scottish entrepreneur Hugh Matheson. Today, our copper operations around the world are at various stages in the mining lifecycle, from exploration to

Productivity in the Chilean Copper Mining Industry

Productivity in the Chilean Copper Mining Industry

The mining sector, specifically, the copper mining industry, is essential to Chile's economic and social development. Mining contributes significantly to national income, tax revenue, jobs and business opportunities, and, ultimately, the country's growth. Given its importance, the Government has requested us to review the evolution of pro

Freeport-McMoRan – New Mexico Operations

The copper mining process is highly regulated – from exploration to extraction to processing – is highly regulated. To comply with these regulations can take years of planning and cost tens of millions of dollars. Once copper ore is extracted and mined, it’s treated to remove copper-bearing material through one of two ways This is done

How Hydrometallurgy and the SX/EW Process Made Copper

How Hydrometallurgy and the SX/EW Process Made Copper

Beginning in the mid 1980s a new technology, commonly known as the leach-solvent extraction-electrowinning process or, SX/EW Process, was widely adopted. This new copper technology utilizes smelter acid to produce copper from oxidized ores and mine wastes. Today, worldwide, approximately 20% of all copper produced is produced by this is process
