It is the case of the slags produced by the iron and steel, the copper and nickel sulphide.copper slag furnace slag copper,Copper slag as fine aggregate for high performance . - WIT Presscharacteristics were examined. The effect copper slag as replacement of fine aggregates on the strength, setting time and durability of concrete mixtures was also studied by Toshiki et al. . Recently, Demirboğa and Gül  used blast furnace slag aggregates to produce high strength concrete. Different water/cement ratios.John Frank
Slags are waste minerals produced during furnace smelting of minerals. The contained values of base metals may be released into the environment under natural weathering conditions polluting ground and underground water. Copper losses into slag are a continuous problem in pyrometallurgical smelting operations.
Dec 29, 2013 . In the paper, results of a study on reduction of blister copper flash smelting slag with the use of anthracite dust are presented. The material, following proper preparation, can be used for slag processing as a substitute for currently applied coke breeze. Keywords: copper, slag, reduction, flash furnace,.
All experiments were carried out under conditions where three phases were present (copper–matte–slag), which is the condition typically prevailing in many slag-cleaning electric furnaces. The %Fe in the electric furnace matte was varied between 0.5 wt.% and 11 wt.%, and two different Fe/SiO2 ratios in the slag were used.
Copper loss in the slag of Khatoonabad flash smelting furnace is estimated to be about 1–3 %. At present, the electric slag cleaning furnace is used for the recovery of copper from slag. However, due.
The recovery of copper from reverberatory furnace slag utilizing flotation has been studied. The effective factors such as particle size, pH, the amount and type of collector and additives, and flotation time were examined. The effect of cooling rate on flotation behavior of the slag was also studied. For an air-cooled slag at.
One furnace would produce 1 ton of copper per day as regulus assaying between 50% and 60% copper (Smalberger, 1975). These smelters were shut down in 1919 and never restarted. The smelters produced approximately 200 000 tons of slag. They were later transformed to sulphur burners of pyrrhotite concentrate for.
characteristics were examined. The effect copper slag as replacement of fine aggregates on the strength, setting time and durability of concrete mixtures was also studied by Toshiki et al. . Recently, Demirboğa and Gül  used blast furnace slag aggregates to produce high strength concrete. Different water/cement ratios.
May 1, 2007 . It is also found that the utilisation of copper slag in manufacture of cement offers a significant saving in fuel. Using copper slag as a raw material for the manufacture of OPC. Materials and methods: The raw materials - line, copper slag, granulated blast furnace slag and bauxite were characterised for.
About 2.2. tonnes of copper slag result in every ton of copper production. Approximately 24.6 million tons of. slag are generated from the world copper industry (Gorai et al, 2003). The copper slag is a by-product. of operation of reverberatory furnaces. Impurities form a less dense liquid floating on top of the copper. melt.
Processes have previously been described in which carbothermic reduction has been carried out in electric furnaces (1-3). The aim of a slag cleaning process is to maximize the recovery of valuable metals (such as Co, Ni, and Cu) in an alloy with the lowest possible iron content. The amount of metallic iron produced should.
May 25, 2017 . Several traditional reducing agents, such as pulverized coal, coke, diesel and natural gas, can be used to reduce magnetic iron in copper slag in an electric furnace with the blowing and stirring method. The main elements of waste cooking oil are C, H, and O; thus, the chemical composition of waste.
Jun 12, 2010 . The aim of the present study was to characterize the fayalite crystal phases in two types of copper slag – flash smelting furnace slag (FS) and converter (CS) slag, given their possible use in adsorption and catalytic processes. Two typical slag compositions different in chemical composition and way of.
However, there are no universal methods to recover copper from copper- bearing slags as the chemical and phase composition of a slag depend on factors such as the type of ore mined and the type of pyrometallurgical process utilized (Shen and. Forssberg, 2003). The reverberatory furnace slag that has been dumped in.
