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,
general adoption of flotation process, influencing the development of the reverberatory furnace, which generally has replaced the blast furnace in smelting operations, with resultant benefits in the cost of copper smelting. Types of Ores & Methods of Treatment. From the milling standpoint, copper ores may be classified roughly as follows: Ores

Jun 23, 2013· Effective costs of Copper Processing Example of porphyry copper mine processing costs A typical smelter contract for copper concentrates issummarized in Table 2. Consider a porphyry copper minetreating an ore containing 0.6% Cu to produce aconcentrate containing 25% Cu, at 85% recovery.
include the costs and capacities of the waste dumps, costs and construction requirements of the haul roads outside of the pit limits, and certain geotechnical characteristics of the saprolite within the project area.
• Ore sorting can be used in copper processing for: Upgrading ore to reduce haulage, reduce processing costs a nd improve the overall capital cost position along with; Removing GAC minerals in heap leach applications. • Heavy Medium Separation can be used on some copper ores to improve project economics.

For general analysis of operating over periods of a year or more, proration of costs may be useful. Gardner has presented prorated costs for a number of copper-mining companies in tables 63 and 64 of Bulletin 405. In the same bulletin, tables 53 to 62, inclusive, present additional data on cost of producing a pound of copper.

Based on abundant experiences on copper mining project Prominer supplies customied solution for different types of copper ore.
Dec 31, 2015· This was lower than the average cost of copper production in 2Q14, which was $1.655 per pound of copper produced. The above graph gives details of copper production costs
This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. Rock characteristics for both ore and waste are typical of those of granite or porphyritic material. Operating conditions, wage scales, and unit prices are typical for western U.S. mining operations. All costs listed are in 2012 US$.
Production costs of the non-ferrous metals in the EU and other countries: Copper and zinc. Author links open overlay panel Aikaterini In 2013, the industry imported copper ore mainly from Chile, Peru and Brazil (Eurostat, 2016a also reported difficulties in distinguishing between energy costs for primary and secondary processing.
The mining rate is designed to feed the 2.3Mtpa processing plant with ore blending to produce a copper feed grade of around 3.7%. Depending on the mining sequence, the mining rate may differ from the processing rate due to stockpile build or withdrawal. Typical working stockpile inventory is
The KS Mine comprised a large open pit mine feeding gold-copper ore to a 52,000 tonnes per day (t/d) processing plant. Between 1998 and 2011, KS produced approximately 3.0 million ounces of gold and 750 million pounds of copper from 218 Mt of ore. Open pit mining and processing ceased in March 2011 on depletion of the mineral reserves.
Ore Grade The costs of mining and processing copper are more closely related to the gross tonnage of the 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 con-tains more copper, it requires less of these inputs

Processing Copper Ores; Resources and Glossary; Hands-On Activity Guide: Copper Electrolysis; Copper Mining and Processing: Life Cycle of a Mine The development stage usually takes 4-12 years to open an ore deposit for production, and may cost anywhere from $1 million to over $1 billion to complete depending on the type of mine. Development
The Old Metallurgical Engineer and Steelmaker says: You could build a cupola to produce 200,000 NTMH (“net tons of hot metal” liquid iron) per year, at a capital cost of approximately $60 million, and an operating cost of approximately $150 per
1.1 PHASES OF A MINING PROJECT There are different phases of a mining project, metallic material of the ore in a process called silver, and copper ores, that merits separate attention because of the serious environmental and public safety impacts. With leaching, finely

Extracting copper from other ores. Copper can be extracted from non-sulphide ores by a different process involving three separate stages: Reaction of the ore (over quite a long time and on a huge scale) with a dilute acid such as dilute sulphuric acid to produce a very dilute copper(II) sulphate solution.
