Flash smelting and oxygen bottom-blowing smelting are the major processes to produce matte from copper concentrates. The common requirements for copper smelting are large production capacity, energy saving, and environment friendly [].As a new technology, oxygen bottom-blowing smelting has the advantages of strong applicability of …

A cupola furnace is the most frequently used furnace aggregate for cast iron production. A by-product of the production of cast iron in cupola furnaces is cupola slag. Its amount is 40–80 kg per 1 tonne of the produced cast iron, and that is one of the reasons why this material is not as favoured as, for example, the blast-furnace slag. The purpose …
During the pyrometallurgical extraction of copper, a significant fraction of this metal is lost with discard slag, which decreases profits and overall copper recovery.
In recent years, the construction industry has struggled with a variety of issues such as material availability, supply channel management, and the increasing cost of construction materials. These issues have encouraged the search for replacements and substitutes for existing construction materials. Blast Furnace Slag is used in the …
Metals 2021, 11, 992 3 of 15 thereby of interest to investigate how the mentioned phenomena influence settling and slag copper content on an industrial scale. Given the above, a project was initiated to obtain fundamental insights into the
Furnace Slag. LF slag, or refining slag, is a basic slag produced in the final stages of steelmaking, when the steel is desulfurized in the transport ladle, during what is generally known as the secondary metallurgy process. From: Sustainable and Nonconventional Construction Materials using Inorganic Bonded Fiber Composites, 2017.
5) Noranda-Teniente with dry feed – Slag Flotation and. 6) Noranda Reactor (filter cake) - Peirce-Smith Converting – Slag Flotation. The Flash Smelting had the lowest energy consumption with 10,784 MJ/t of anode copper and the Noranda Reactor the highest energy consumption with 13,072 MJ/t of anode copper.
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 concentrates now available. The …
12.3 Primary Copper Smelting 12.3.1 General1 Copper ore is produced in 13 states. In 1989, Arizona produced 60 percent of the total U. S. ore. Fourteen domestic mines accounted for more than 95 percent of the 1.45 megagrams (Mg)
Air-cooled copper slag has a black colour and glassy appearance. The specific gravity varies with iron content, from a low of 2.8 to as high as 3.8. The unit weight of copper slag is somewhat higher than that of conventional aggregate. The absorption capacity of the material is typically very low (0.13%).
Copper slag and stainless steel slag of Electric Arc Furnace (EAF) are two typical metallurgical solid wastes, which contain a large number of valuables, such as Fe, Cr, and Cu.

Electric Arc Furnace Slag (EAFS) is one of the primary by-products of the steel recycling industry, which comes out initially as large pieces, that can be further crushed and be used as aggregates in infrastructure materials. While being a waste product, the relatively high strength of the aggregates means that EAFS can provide favorable ...

1222 CHAPTER 04 Nonferrous Pyrometallurgy INTRODUCTION Copper is present in a smelting slag from Teniente Converter (TC) in the form of mecha-nically entrained matte inclusions and dissolved copper.
The pyrometallurgical copper production route typically involves a three-step process from feed to anode: (s)melting, converting and fire refining.1 Two types of furnace are in use in the refining section: the rotary furnace type dominates in primary copper production, while secondary smelters tend to use hearth refining furnaces because they …
Previously, we analyzed the phase composition and formation mechanism of the slag crust of commercial blast furnaces (The volume is 2680m 3 ) equipped with copper staves in China, but we did not ...
