  • Slags, copper smelting Registration Dossier ECHA

    EC number: 266-968-3 CAS number: 67711-92-6 Slag resulting from the smelting of a heterogeneous mixture of copper and precious metals from primary and secondary sources and plant reverts. Major constituents are iron oxide and silicon dioxide with minor amounts of copper, lead, nickel and various non-ferrous metals and oxides.

  • Copper Slag an overview ScienceDirect Topics

    Copper slag, or fayalite slag, is a by-product obtained during the matte smelting, converting and refining of copper (Fig. 7.11). 54,59 It has been estimated that for every tonne of copper produced, about 2.2 tonnes of slag is generated, 60 as a consequence of the relatively low grades of copper

  • Copper processing Roasting, smelting, and

    2 天前 · 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 furnace of either the hearth or

  • RECOVERY OF PIG IRON FROM COPPER SMELTING SLAG

    2018-11-16 · of copper slag are iron oxide and silica. T hese exist in copper slag mainly in the form of fayalite (2FeO·SiO 2). This study was intended to recover pig iron from the copper smelting slag by reduction smelting method. At the reaction temperature of below 1400°С the whole copper smelting slag was not smelted, and some agglomerated, showing a

  • What is a Copper Slag? (with pictures) wiseGEEK

    2020-7-15 · Copper slag is a by-product created during the extraction of copper from copper ore. This material represents a popular alternative to sand as a blasting medium in industrial cleaning. Using blasting or high-pressure spraying techniques, companies can use copper slag to clean large smelting furnaces or equipment.

  • Copper Smelting Chemistry Tutorial

    2019-6-21 · Any copper(I) oxide present will be converted into copper(I) sulfide during the smelting process because copper has a higher affinity for sulfur than it does for oxygen. for example: Cu 2 O + FeS → Cu 2 S + FeO. Impurities form a slag which floats on the surface and is easily removed. One of the reactions to remove iron impurities is shown below:

  • How Minor Element Affects Copper Matte Smelting

    2020-7-24 · In the area of copper smelting, one study focused on the quantitative determination of the interaction coefficients in the systems Cu-Pb-Bi and Cu-Pb-Sn. The present work investigates the possible existence of minor-element interactions in the copper matte-slag system, but does not present interaction coefficients.

  • Mesoamerican copper smelting technology aided

    2020-3-31 · But the Spanish desperately reqired large quantities of copper and tin, and in consultation with indigenous smelters introduced some European technology into the process. Hosler and her colleagues excavated an enigmatic feature that consisted of two parallel courses of stones leading toward a large cake of slag in the smelting area.

  • Copper Final Slag and Smelting Data from the

    Slag, copper smelting (high quality slag products) is defined as: Substance produced, from heterogeneous mixtures of copper contained material formed during copper production, by reduction at high temperature in molten state (i.e. melting and processing in a furnace) or by flotation processes.

  • Recovery of iron from copper flash smelting slags:

    2018-6-29 · Copper slag contains iron in the range of 42–45%, which can be recovered and recycled along with the contained copper to obtain an iron–copper alloy and a final slag rich in oxides. Therefore, the present work shows the experimental results of the reduction of a flash smelting slag using coke as reductant up to 150% of the stoichiometric

  • Minimization of Copper Losses in Copper Smelting

    During the last few decades, the pyrometallurgical processes used for cleaning copper smelting slags have been steadily optimized. The electric furnace or rotary slag-cleaning furnace are now generally used to perform this task, giving a level of copper in discard slag typically in the range of 0.55 wt.% and 1.3 wt.%, with most plants reporting copper losses in the discard slag in the range of
