The reaction of these processes can be written as: 2CuFeS2+2SiO2+4O2 → Cu2S+2FeSiO3+3SO2. The copper extracted from this process is mixed with the slag and is called Matte Copper due to its texture and appearance. This mainly consists of Cu2S which is reduced to pure metal by blasting Matte Copper with air. Cu2 S+O2 → 2Cu+SO2.
Copper minerals and ores are found in both igneous and sedimentary rocks. Mining of copper ores is carried out using one of two methods. Underground mining is achieved by sinking shafts to the appropriate levels and then driving horizontal tunnels, called adits, to reach the ore. Underground mining is, however, relatively expensive and is ...
A schematic diagram of the conventional process for the production of copper and the SX/EW process can be seen here. Conventional Copper Extraction . Conventionally, copper is recovered by a pyrometallurgical process known as smelting. In this process copper ore is mined, crushed, ground, concentrated, smelted and refined.
The first step, mineral processing, is to liberate the copper minerals and remove waste constituents—such as alumina, limestone, pyrite, and silica—so that the copper minerals and other nonferrous minerals of …
Copper Mining and Processing: Processing Copper Ores. View PDF Download PowerPoint. Oxide and sulfide ores undergo different processes to be purified into 99.99% pure copper. Copper processing is a complicated process that begins with mining of the ore (less than 1% copper) and … See more
Introduction. This is an interactive activity that allows students to explore the processes involved in the mining and processing of copper ore and the production of copper. Students initially place the processes in correct sequence and can then select each stage to animate it and access relevant information.
This flowchart made of machinery icons explains or expresses in simple but clear terms the step of the Copper Mining and …
Manufacturing Process of Copper. Copper processing is a complex process that involves many steps as the manufacturer processes the ore from its raw, mined state into a purified form for use in many industries. Copper is typically extracted from oxide and sulfide ores that contain between 0.5 and 2.0% copper.
The flotation concentrate is then dewatered and filtered to produce a filter cake that is sent to a copper smelter. Copper processing - Ores, Refining, Smelting: Principal forms in which copper ores are found include native copper, porphyry copper, massive deposits, and mixed ores. Native copper is simply the metal found unadulterated in nature.

This mining method is performed by a person remotely while in a cabin on the surface and they use a television camera in order to control and monitor the continuous miner machine. Dredging. This is a surface mining process where the mineral materials from the bottom of the water such as rivers, oceans and lakes are retrieved. Strip Mining

The Mineral Processing Flowsheets shown on the following pages are based on actual data obtained from successful operating plants. Metallurgical data are shown in these flowsheets which incorporate Crushers, Grinding Mills, Flotation Machines, Unit Flotation Cells, and Selective Mineral Jigs as well as other standard milling …
Copper processing begins with mining copper ore, which contains less than 1% of copper, and ends with sheets of 99.99% pure copper (cathodes). Copper mining generally takes place through open-pit …
If you have any enquiry or wish to discuss your project, contact us. +34 946 74 05 00. We design and manufacture a wide range of filter presses to dewater coal, mine tailings or minerals ore concentrates, like zinc or copper.
The membrane process achieved high water fluxes (15.5 ± 0.2 L⋅m − 2 ⋅h − 1 ), salt rejections (98 %) while precious metal recovery (91 %) was achieved through adsorption processes [15].
A simplified schematic drawing of copper flotation flowsheet. Run-of-mine open pit ore will be crushed in a gyratory crusher. The crushed ore will be processed by means of semi-autogenous and ball mill grinding followed by rougher flotation, regrind, cleaner flotation, and dewatering to produce copper concentrate. The concentrate will be …

IN PROCESSING COPPER ORES In recent times, a low copper content in ores has been observed (ores containing 0.2–0.3% copper are used for processing in Canada and the United States, and ores containing at least 0.4% copper are used in Russia [4]) owing to the exhaustion of rich copper resources. The flowsheet of processing copper ores is
Sustainability includes three dimensions: social, environmental and economic, i.e. people, planet and profit. This means that sustainable metals production is not only environmentally friendly and ...
The use of seawater in mining is an essential issue because it is considered as a more sustainable alternative instead of use freshwater or desalinated seawater, especially in locations with complex water availability, as is northern Chile. Keywords: Pourbaix diagrams, Eh-pH diagrams, seawater, copper minerals, Chilean mining 1.
Mining - Underground, Safety, Techniques: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, which, for each ton of …
Copper processing - Roasting, Smelting, Converting: Once a concentrate has been produced containing copper and other metals of value (such as gold and silver), the next step is to remove impurity elements. In older processes the concentrate, containing between 5 and 10 percent water, is first roasted in a cylindrical, refractory-lined furnace of …
According to data about the world copper mine production expressed in million metric tons of Cu content for the first years of twenty first century [5], it is clear that there is an almost steady ...
The Process. The concentrated ore is heated strongly with silicon dioxide (silica) and air or oxygen in a furnace or series of furnaces. ... The purification uses an electrolyte of copper(II) sulfate solution, impure copper anodes, and strips of high purity copper for the cathodes. The diagram shows a very simplified view of a cell. At the ...
Figure 1: Overview of copper production Benefication process Figure 2: Overview of a typical beneficiation process at a concentrator Sulfidic copper ores are too dilute for direct smelting.
