Washed sand from Erzeni riverbed, (a river near Tirana, Albania) is used for producing of mortar prisms [6]. disadvantages of clay can be overcome by stabilizing with suitable material. Copper slag is the waste material of smelting and refining of copper such that each ton of copper generates approximately 2.5 tons of copper slag. Industrial Single Furnace Direct-to-Copper Smelting 182 10.4. Waste slag is removed. Electrowinning 9 1.4. The copper ore treatment process in RTB Bor produces significant amounts of mine waste material such as: mining waste, flotation tailing and copper slag (Stanojlovic et al., 2014). Cu-in-Slag Limitation of Direct-to-Copper Smelting. As the initial setting time is high, this cement is not used for emergency or repair works. This also wastes time, because the welder has to clean away the slag to make a presentable product or welding job. 11.2. 11.4. Summary. SolventExtraction 8 1.3.2. 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 smaller, and its cross section is rectangular. and copper slag processing plant, which are located in and around Bor, plus the Majdanpek mine and flotation processing plant located some 80 km northeast of Bor. 10.10. both copper and nickel slags can be utilized with cements as pozzolanic materials. Copper Slag an overview ScienceDirect Topics. Steel slag is a steel-making waste from the steel industry and is reused as it is in many engineering fields, including transportation and highway engineering, environmental engineering, and geotechnical engineering. 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 Recovery of Cobalt and Copper from Nchanga Mines Slag INTRODUCTION . TIG welding is very clean and leaves no slag at all, so the welder can concentrate on welding instead of cleaning up the metal. They are considered as potential natural hazard, which can cause extensive damage to structures if not adequately treated. Copper Slag is one of the waste byproduct produced by ‘Hindustan Copper limited’, Khetri, Rajasthan, India. It is usually pulverized to the size of fine sand. Metal droplets fall to the weld pool and join the work pieces. copper slag as a replacement of fine aggregate on the strength properties and concluded that Maximum Compressive strength of concrete increased by 55% at 40% replacement of fine aggregate by copper slag and flexural strength increased by 14 % for 40 % replacement. Chemistry 184 10.5. Disadvantages Of Steel Slag. Copper slags are considered as a waste product of pyrometallurgical copper extraction from ores. The Ideal Direct-to-Copper Process 179 10.3. Blast furnace ironmaking is inseparable from the coke source, but the coke resources are getting less and less, but the price is getting higher and higher, the cost of iron making will be higher and higher, and it is likely that one day will meet the depletion of coke resources. Concentration by Froth Flotation 4 1.2.2. slag, refining slag, or flue dusts), and copper-alloy scrap. It is used as either an additional or substitute material in road construction, filter or soil stabilizer in these cases. Copper Slag is one of the waste byproduct produced by îHindustan Copper limited, Khetri, Rajasthan, India. In parallel with the copper slag treatment work, the CSIRO was continuing to work in tin smelting. Direct-to-Copper Impurities. Chapter 11. 3. What makes Pyromet’s launder design innovative and safe is that it does not have any cooling water channels underneath the launder runner, whilst achieving effective cooling of the runner. Development policy and plans of Our researcher experts helps us to present our clients with a comprehensive and in-depth analysis of Copper Slag market. Based on over 150 published studies, this paper provides an overview of mineralogical and geochemical characteristics of different types of slag and their environmental consequences, particularly from the release of potentially toxic elements to water. High % Cu-in-Slag from No-Matte-Layer Strategy 186 10.8. Industrial Details 185 10.7. Despite increasing rate of reusing copper slag, the huge amount of its annual production is disposed in dumps or stockpiles to date. The slag reaches a temperature of about 3500°F (1930°C). Before the electric furnace, the fayalite slag shows a share of around 65–80% in mechanical losses. Copper tailing is the waste rock remaining after ore has been processed to remove the copper. Main laboratory tests include Un-confined compressive strength test (UCS), California bearing ratio test (CBR). The slag/metal distribution ratio of indium between molten copper and slags in the copper saturated CaO-SiO 2 -FeO x system with Fe/SiO 2 = 1.1 to 1.2 and CaO contents between 4 wt. Control 186 10.7.1. Expansive soils are a worldwide problem that creates challenges for Civil Engineers. Copper slag is a by-product created during the copper smelting and refining process. Converting 5 1.2.4. The maximum compressive strength of concrete attained at 40% replacement of fine aggregate at 7 and 28 days.

The waste copper slag can be used as abrasive tools, road construction, and ballast. Expansive soils are a worldwide problem that creates challenges for Civil Engineers. Per ton of copper produced, 2.2 tons of slags are generated. This inert slag can also be used for land filling, for making of road and in construction works like embankment for rivers, etc., Converter slag (0.36 kg/kg of copper) produced from SWIL and slag (1.6 kg/kg of copper) from Birla copper (Sharma, 1998a, Sharma, 1998b) is granulated and sold out to the construction companies for road making, as abrasives for shot blasting media. Minerals are concentrated into slurry that is about 15 % of copper. They are considered as potential natural hazard, which can cause extensive damage to structures if not adequately treated. copper slag that are 0%, 20%, 40%, 60%, 80% and 100%. Water is recycled. The report includes data analysis about the market status, competition pattern, advantages and disadvantages of enterprise products, development trends, and regional industrial layout characteristics. Copper losses in the slag can generally be split into two categories. Fire RefiningandElectrorefining ofBlister Copper 7 1.3. In C219, slag cement is defined as a "blend of granulated blast-furnace slag and hydrated lime in which the slag constituent is more than a specified minimum percentage." Slag is a waste product from the pyrometallurgical processing of various ores. The production of Copper Slag is 120-130 lakh ton per annum. Decreasing Copper in Slag II: Minimizing Copper Concentration in Slag. For this reason, with each cementing material, mortar prisms 4x4x16 cm are moulded and tested in order to determine the limits of practical use of slag addition. I. 10.11. Copper slag is a by-product obtained during smelting and refining of copper. However, these processes have some disadvantages such as high temperature, energy consumption and production cost. Blast Furnace Disadvantages: 1. 10.9. Copper slag is one of the materials that is considered as a waste which could have a promising future in construction Industry as partial or full substitute of aggregates. Collectively, these materials make up slag, which can be used for a surprising number of applications in the building and industrial fields. 7.11). The disadvantage of the reduced strength at early age can be managed by adding an optimal amount of slag. Copper Loss in Slag 11.1. Some welding methods leave slag when they are finished, making the finished product look sloppy. The split tensile strength and the flexural strength were also obtained higher strength at 40% replacement level at 28 days. 2312 Words 10 Pages.
