(SiO2 FeO Fe3O4 CaO Al2O3) and the content of copper in the matte on resulting copper content in the slag during smelting of the sulfide concentrates in the reverberatory furnace When comparing results obtained with MLRA model calculations with values measured at industrial level high degree of fitting is obtained (R2 = 0 974) slag refining slag or flue dusts) and copper-alloy scrap The construction of the furnace is basically related to that of the iron blast furnace but there are considerable differences in design especially in size and shape: the copper blast furnace is lower and

A Study on the Recovery of Iron from Copper Slag with

Since the copper smelting slag contains high content of Fe Cu and valuable metals interest in recycling it is increasing The high Fe content in the copper smelting slag can be used as a high-value element that can replace the foundry pig iron Therefore this study was intended to recover Fe-Cu alloy from the copper smelting slag

SLAG is a broad term covering all non metallic co products resulting from the separation of a metal from its ore Its chemistry and morphology depends on the metal being produced and the solidification process used Slags can be broadly categorized as ferrous (iron/steel) and non-ferrous (copper lead/zinc) depending on the industry from which

In this context "tailings" is waste rock at a mine after the ore has been processed to remove the metal It has usually been pulverized to fine sand "Copper slag" will be the slag skimmed off molten copper in a furnace It is generally formed fr

Sep 21 2012During 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

copper slag furnace slag copper copper slag furnace slag copper XSM excellent mining crushing machinery products or production line design the company is committed to building the Chinese brand mine crushing and processing machinery mainly crusher mill sand making our products (copper slag furnace slag copper) in more than one hundred of the worldsales of

Mar 07 2020Copper slag is a by-product created during the copper smelting and refining process As refineries draw metal out of copper ore they produce a large volume of non-metallic dust soot and rock Collectively these materials make up slag which can be used for a surprising number of applications in the building and industrial fields

Melting should be performed without excessive losses of copper either by volatilization or in any slag which cannot be returned to the blast furnace or reverberatory furnace for re-smelting The process should be susceptible to ready mechanical manipulation for charging and tapping

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

Copper slag can also be used as a building material formed into blocks Copper slag is widely used in the sand blasting industry and it has been used in the manufacture of abrasive tools In general the spent copper slag is suitable to be used as a fill material for land reclamation

Some properties of a typical copper slag are shown in Table I and it can be observed that air-cooled copper slag has a black colour and glassy appearance The specific gravity varies with iron content from 2 8 to 3 8 The unit weight of copper slag is somewhat higher than that of conventional aggregate The absorption capacity of the

Granulated copper slag is more porous and therefore has lower specific gravity and higher absorption capacity than air-cooled copper slag The granulated copper slag is made up of regularly shaped angular particles mostly between 4 75 and 0 075 mm (No 200 sieve) in size (Emery 1986 Hughes and Haliburton 1973)

Copper Slag and Blast furnace slag and attained maximum value at 8 25% and 7 12% respectively and again decreases 3 With the increases of Copper Slag and Blast furnace slag percentage Liquid Limit and Plasticity Index goes on decreasing 4 It is concluded that the optimum value for both Copper Slag and Blast furnace slag is 20% 5

Copper Slag Cleaning Furnace – Made in China

Upgrading Copper Slag Cleaning Tailings For Re Use In terms of copper recovery it is thus quite important how the copper slag has been processed and cooled post the smelting or converting furnace EF and prior to the milling and flotation step

Project Report on Copper Slag in Concrete Today I'm going to be shared about Project Report on Copper Slag in Concrete With advantages and disadvantages of copper slag in concrete so let's get started Introduction Traditionally soil stone aggregates sand

Chile has seven copper smelters four that are linked to primary producers (three owned by Codelco and one by Disputada) and three custom smelters (two owned by Enami and one by Noranda) Each smelter employs a different strategy for slag cleaning thus each smelter obtains different results This article outlines and compares the different slag-cleaning systems that

Copper smelting slag is a solution of molten oxides created during the copper smelting and refining process and about 1 5 million tons of copper slag are generated annually in Korea The oxides in copper smelting slag include ferrous (FeO) ferric oxide (Fe2O3) silica (SiO2 from flux) alumina (AI2O3) calcia (CaO) and magnesia (MgO) The main oxides in copper slag which
