In the case of the copper ISASMELT™ process developed in Mount Isa the commissioning of the commercial furnace in 1992 was the culmination of 14 years of bench, pilot and demonstration scale testwork. The demonstration plant was operated from 1987 to 1992, initially at a feed rate of 12 t/h of concentrate increasing to a maximum of 50 t/h during trials performed to reduce the scale-up factor between demonstration plant and commercial plant. The commercial commercial scale copper ISASMELT™ furnace in Mount Isa was commissioned in August 1992 with a capacity rated at 180 000 tonnes per year of copper anode. In 2013 the copper ISASMELT™ has been operating for 21 years which is a Coming of Age birthday in Australia. After two major smelter upgrades in 21 years the original furnace is still in service and routinely treats in excess of 1 000 000 tonnes per annum of copper containing feed and has a demonstrated campaign life, using uncooled refractory, approaching 4 years. Pyrometallurgy PY02 OUTOTEC® SMELTING – INTEGRATED, INTEGRATED, SUSTAINABLE PLANT SOLUTIONS Fagerlund, K ABSTRACT Outotec has a very unique and exceptional combination of different types of smelting process technologies together with the state-of-art products and continuous development in our research laboratories and pilot- plants. World’s leading smelting technologies are all now within the Outotec family: Outotec ® Flash Smelting, KennecottOutotec Flash Converting, Direct Blister Flash Smelting, Ausmelt TSL, Kaldo, Troff, Electric Furnace, Fire-refining and Anode Casting. Outotec is not only able to evaluate the available various complex raw materials but also to provide the best available solution for the specific project. This paper will provide examples how to cross-utilize and apply knowhow, expertise from different technologies and products in an innovative way to provide sustainable solutions for copper industry. In addition, social responsibility and increasing governmental regulatory requirements brings new demands to the copper producers, thus environmental approvals for the new and existing smelting plants have become increasingly more difficult to acquire. This paper will provide an examples how to combine overall process knowledge together with modern tools to enable reliable and effective data for decision making, especially while discussing with different authorities, stake-holders and investors. Selection of best-available-technologies with proven references can ensure the long operational lifetime of the smelters. Also, modernization and upgrade investments of the operational plants can be better justified by taking into consideration not only the economical but also environmental aspects. Examples will be provided where where safety, campaign life, furnace integrity all contribute into the plant life-cycle, where Outotec new cooling solutions can provide considerable improvements and can be flexibly applied in the operating plants and also in wide variety of different applications. Pyrometallurgy PY03 WEAR PHENOMENA OF BASIC BRICK LININGS IN THE COPPER INDUSTRY D. Gregurek, C. Majcenovic RHI AG; TC Leoben; Magnesitstrasse 2; Leoben, A-8700, Austria A. Spanring, M. Kirschen RHI AG; Wienerbergerstrasse 9, Vienna, A-1100, Austria ABSTRACT In the non ferrous metals industry particulary in the copper smelting furnaces the refractory lining made of magnesia-chromite bricks is exposed to several stresses rather complex in their interaction. These can be classified as chemical, thermal and mechanical stresses occurring as a single wear factor or in combination. The chemical factors include corrosion caused by acidic slag and gaseous SO 2 diffusion, redox effects and in particular cases hydration. In most of the non-ferrous metallurgical processes the chemo-thermal load by Fe-silicatic slags of fayalithic type is a common wear mechanism of the magnesia-chromite bricks. Nevertheless the extraordinary massive SiO2-supply caused by changes in the processing and the uncontrolled addition of silica sand results in a severe formation of forsterite respectively in a volume expansion due to “forsterite bursting”. Increased bursting”. Increased temperature level respectively changes in the temperature during the furnace operation as well as the copper metal infiltration into the brick microstructure are further wear factors on thermal side. The hot erosion is the dominant mechanical factor. Therefore understanding of wear mechanisms through “post mortem investigation” and praxis field trials are highly important to ensure product investigation” recommendation for industrial application. Pyrometallurgy PY04 CORROSION TESTING METHODS FOR NEWLY DEVELOPED REFRACTORY PRODUCTS D. Gregurek, A. Ressler, V. Reiter, RHI AG, TC Leoben, Magnesitstrasse 2, Leoben, A-8700, Austria A. Franzkowiak, A. Spanring RHI AG, Wienerbergerstrasse 9, Vienna, A-1100, Austria ABSTRACT The processing routes in the base metals industry, especially copper smelting, converting and fire-refining, have recently undergone significant changes in terms of slag chemistry, temperatures, redox and more frequently deviating raw material compositions (blended low-grade fractions) in the primary smelter feed. All these parameters significantly influence the performance of already well-approved refractory linings. Decreased brick lifetimes associated with process changes - also confirmed by the results of post mortem studies - were a clear signal for RHI RH I AG to focus on the development of high grade refractory bricks for chemically stressed areas. In order to determine the most suitable refractory grades and to improve the performance in specific furnace areas, special test methods were selected. The practical test facilities, including an induction furnace, rotary kiln and cup test, at RHI’s Technology Center use use process slags, for example of a fayalithic and Ca-ferritic type, and enable the best possible understanding of brick wear on a pilot scale. A complete mineralogical investigation including thermo-chemical calculations with FactSage were performed to determine the highest influencing wear parameters. Optimized and engineered Pyrometallurgy lining solutions for the copper industry can be provided based on the acquired knowledge from test results in combination with praxis trials. Pyrometallurgy PY05 ELECTROMAGNETIC LEVEL PROFILE MEASUREMENT SYSTEM TESTED BY AGELLIS GROUP AB ON KENNECOTT COPPER FLASH SMELTERS IS DESIGNED TO ENHANCE PROCESS CONTROL DECISION MAKING AND IMPROVE OPERATOR SAFETY. N. Brogden, JP. Nilsson, P. Bloemer, A. Lyons AGELLIS Group AB, Tellusgatan 15, 224 57 Lund, Sweden R. Kaur, David Krippner, KUC, Magna Plant, Salt lake City, Utah, USA ABSTRACT Reliable and accurate furnace level information for blister, matte and slag during smelting processes is invaluable for decision making and process optimization, while obtaining such information safely is a necessity. Agellis Group AB had previously identified inherent problems with gauging levels accurately in furnaces. We had successfully installed our EMLI ELP systems on Submerged Arc and other electric furnaces in order to solve measurement problems. In Flash Furnaces the problems appeared to be the same, with sounding bars operated from the furnace roof area being used to take measurements. As a result operators can be at risk and the results are often inaccurate. It was therefore decided to test the ELP system on a flash smelter. This paper shows how the Agellis EMLI-ELP system was successfully trialled at Kennecott Utah Copper (KUC) on both their Flash Smelting (FSF) and Flash Converting (FCF) furnaces. The results were used to compare the accuracy and reliability of o f the Agellis syste...
