Copper concentrators typically treat up to 100 000 t of ore per day. They are located directly at the from the blast furnaces (three in each plant) is mixed with the converter gases (Hoboken Converter). It contains 7 10 % SO2 and is sent to sulfuric acid production.

(30 to 35% mass rejected, with 40% upgrade in Feed Grade) • Ore sorting can be used in copper processing for: Upgrading ore to reduce haulage, reduce processing costs a nd
Chapter 6 Copper Production Technology The last boomin technological innovation for the copper industry occurred in the first two dec-ades of this century, whenopen pit mining, flo- tation concentration,and the reverberatory smelter were adapted to porphyry copper ores. With the exception of leaching-solvent extrac-
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and Copper Extraction Process. Starting from either open-pit or underground mining and using a different relevant treatment method for oxide or sulphide copper mineral (ore). Having a quick look now at how porphyry ores are treated and the metals extracted. There are two main
The four major steps in the production of marketable copper are mining, concentrating, smelting, and refining. In a few instances, however, leaching takes the place of concentrating, smelting, and refining. At present, although considerable leaching and direct-smelting ores are produced, the bulk of the copper ore mined is concentrated. The milling of copper ores as practiced in the larger
Copper processing, the extraction of copper from its ores and the preparation of copper metal or stone compounds for use in various products. In its pure form or as an alloy, copper (Cu) is one of the most important metals in society. The pure metal has a face-centred cubic crystal structure, and
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, due to the different
Design and Construction of a Copper Plant Proceedings of EMC 2015 3 The most advanced environmental-friendly autogenous processing of sulfidic copper concentrates with complete sulfur utilization was applied. The given advantages are: • The metallurgical processes applied at the Copper, Lead and Zinc plants were tied in with the
A recognised leader in copper processing and concentrating, our exceptional expertise and technically advanced methods of delivering copper concentrators and processing plants has resulted in cost effective projects being successfully completed on time and on budget, with excellent safety performance.
Copper extraction refers to the methods used to obtain copper from its ores.The conversion of copper consists of a series of physical and electrochemical processes. Methods have evolved and vary with country depending on the ore source, local environmental regulations, and other factors.

Control of SO2 from smelters is commonly performed in a sulfuric acid plant. Use of a sulfuric acid plant to treat copper smelter effluent gas streams requires that particulate-free gas containing
The second part discusses the practical requirements for designing a copper electrowinning plant. BEUKES, N.T. and BADENHORST, J. Copper electrowinning: theoretical and practical design. Hydrometallurgy Conference 2009, The Southern African Institute of Mining and Metallurgy, 2009.
The processing plant will be designed with two distinct operating mode. The mode used s will depend on the ore being treated. Oxide ore with a low copper content will be treated at a nominal throughput of 500000, t/year through a hybrid carbon-in-leach (CIL) plant to recover gold as bullion.
The project increased the overall processing capacity to 85,000 t/d (an increase of over 30,000 t/d) with annual copper production averaging 165 million pounds. Achieved over 1 million manhours without a lost-time incident. Minimal interruption to existing production during plant shutdown.
plant and/or full-scale plant. In the case of leaching and CIP/CIL, such data are relatively easy to obtain for existing plants, assuming that the problem is one of the design of an upgrade for an existing plant. In the case of a new plant, such data are much more difficult to come by, particularly if the ore is from a deep underground mine.
• Copper revenue USD 1.10/lb: • Cobalt revenue USD 10/lb: • Total production of copper throughout LOM 2.17 millions tonnes (4 778 million lb); • Total production of cobalt throughout LOM 0.113 millions tonnes (250 million lb). The project is most sensitive to a change in copper recovery and operating costs.

The plant consists of an IsaSmelt furnace, a matte-settling electric
The SX/EW Process is a hydrometallurgical process since it operates at ambient temperatures and the copper is in either an aqueous environment or an organic environment during its processing until it is reduced to the metal. Because of its dependence on sulfuric acid, the SX/EW Process is at present not a substitute for, but rather an adjunct
The mining, crushing and grinding portions of the processing are extremely energy intensive since the rock must be reduced essentially to talcum powder fineness in order to separate the copper-bearing minerals from it. the pregnant liquor is pumped five miles from the leach site to the SX/EW plant. The electrowinning of copper requires
The steps involved in opening a mine and processing copper ore into a final product are very complex. This module will cover basic information about copper, copper mining in Arizona and on tribal lands, the life cycle of a mine, and the specifics of copper processing. LEARNING OBJECTIVES
