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
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 trucked via the existing road network in
The general process flowsheet of the copper smelter used for piloting the COCOP solution is pre-sented in the figure 1. The main raw materials are sulfidic copper concentrates that are first blended to feed mixture and then dried before processing. Flash Smelting Furnace FSF and Peirce-Smith Converters PSC are in the heart of the operation.
consumer such as a copper smelter, this provided some relief to ever rising operating costs. However, analysts expect some rebound in the oil price later this year or into 2016. Hence, energy consumption in smelting, examined in this article for a number of technology congurations, remains an important topic for copper smelters.
Modern copper smelters use processed copper ore fed into a flash furnace, typically fired by oxygen which produces blister copper, being further processed in a converter furnace. Molten copper is poured from here into rectangular moulds, the resulting ingots subjected to electrolysis producing a metal of 99.9 purity. Copper can be recycled indefinitely without the base metal
Copper processing - Copper processing - Roasting, smelting, and 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

Electrowon copper cathodes are as pure as or purer than electrorefined cathodes from the smelting process. Thus they are well received by the market. Whereas the conventional process requires an estimated 65 MJkg of energy not including scrap recycling the SXEW process requires an estimated 15 MJkg from heap or dump leaching to 36 MJkg.
The technical feasibility of recovering copper, nickel, and cobalt from smelting and converting slags using Ausmelts top-submerged lancing process has

Copper Smelting Process. We shall begin by looking at the mining and processing of the copper bearing ore, followed by an examination of an established and a modern copper smelting process Mining for Copper Bearing Ore There are two categories of copper ore sulphide ore which is processed to enrich it before smelting, and oxide ore that is subjected to
Jul 06, 2020 Figure 7 shows the process flowsheet of the lead secondary copper smelter.20 The flowsheet allows the integration and transfer of materials with the primary copper smelter. The lead smelter and refinery involve Smelting of complex copper lead concentrates in an electric furnace. Converting of copper lead matte in a Peirce-Smith converter.
The reverberatory furnace dominated copper matte smelting for much of the 1900s, because it was an excellent process for smelting fine concentrate from flotation. It is a fossil fuel fired hearth furnace for smelting concentrate and producing copper matte. The
The plant is designed to produce 60 000 tpa of cathode copper. The process flow sheet includes a pressure oxidation POX circuit that leaches pyrite flotation concentrate to
and smelting, converting, and refining the re-maining 40 percent. Actual requirements vary widely depending on the mine characteristics and type of smelter, however. Table7-1 shows one estimate of energy requirementsin Btu equiva- lents for a hypothetical copper operation. It is in-teresting to note that pollution control equals a
Hong Yong Sohn, ... Bart Blanpain, in Treatise on Process Metallurgy Industrial Processes, 2014. 22.214.171.124.1 FeOFe 2 O 3 SiO 2 Slags. It has been customary since early times in copper smelting, when acid refractories were used universally, to add SiO 2 to form a slag with the iron that has been oxidized. This is still the most common practice today, though many furnaces
The copper concentrates are fed through the flash smelting furnace with oxygen-enriched air. In the furnace, the concentrates are instantly oxidized, after which they melt and separate by their own reaction heat into copper matte with a grade of 65 and slag consisting of iron oxide, silica, and other compounds.
Recovery of value metals from copper smelter slag by,Fig 7 shows a proposed process flowsheet for the copper, zinc, and iron recovery from copper smelter slag of Balkhash copper plant In this process, crushed slag, with ammonium chloride in a weight ratio 12 is subjected to heat treatment for 120 min at 320 C Chat Online.
Process modeling today is an integral part of process development and design, operation optimization, process control, business evaluation and decision-making. This paper reviews the application of process modeling and simulation in copper metallurgy and discusses its further development, i.e. an intelligent system for smelter. A concept of
Figure 6-2.Early Smelting Technology Charcoal ore flux m The Egyptian copper smelting furnace was filled with a mixture of copper ore, charcoal and iron ore to act as a flux. It was blown for several hours by foot or hand bellows. By the end of the smelt the copper had separated from the slag, which was tapped off.
Jan 01, 2005 Copper concentrates may often contain significant levels of base and precious-metal by-products. Copper smelters are efficient at the recovery of gold, silver and PGMs but often pay poorly and with much delay for these elements. Base metals such as zinc, cobalt and nickel are difficult to recover through a copper-smelter process.
