Softening Behaviour of Lead Sinter and Slag At
Paper Title: THE ISA-YMG LEAD SMELTING PROCESS Paper Presented at: PbZn 2005 Conference, Kyoto, Japan Authors: Bill Errington & Philip Arthur, Xstrata Technology Jikun Wang & Ying Dong, Yunnan Metallurgical Group, Date of Publication: October, 2005 For further information please contact us at [email protected] www.isasmelt.com THE ISA-YMG LEAD SMELTING PROCESS Bill Errington and Philip Arthur Xstrata Technology, Level 4, 307 Queen Street,, Brisbane, Queensland 4000, Australia [email protected] Jikun Wang and Ying Dong Yunnan Metallurgical Group, Kunming,Yunnan, P. R. China ABSTRACT The Yunnan Metallurgical Group (YMG) has constructed a new lead-zinc smelting/refinery complex at Qujing in Yunnan Province, China. The lead smelting process combines an ISASMELT™ smelting furnace with a YMG designed blast furnace. The ISASMELT furnace produces lead bullion plus a high-lead slag that is cast into lump form and fed to the blast furnace. YMG installed a blast furnace in the 1950's to treat high lead slag produced by earlier silver operations. This furnace later treated sinter. For the present project YMG carried out trials at the pilot and commercial scale before deciding on the final blast furnace design. The ISASMELT furnace design was based on the operation of the Lead ISASMELT Plant at Mount Isa. This paper describes the development and the operation of both the ISASMELT furnace and the YMG blast furnace. This combination of new technology and remodelled traditional technology provides an economical solution to achieving an environmentally acceptable lead smelter. Key words: ISASMELT process, lead smelting, lead slag, lead blast furnace www.isasmelt.com 2 INTRODUCTION The new YMG lead smelter forms one part of a new greenfield lead/zinc smelting and refinery complex located at Qujing in Yunnan Province in China. -

Someone who has lived through the problems, had to do the maintenance, operated during a midnight power Of course the big picture must be right – doing the right project, in the right place, failure, cleaned up the spill. Someone at the right time. who has “closed the loop” on previous designs; lived with previous decisions After that, the devil is in the detail. You and improved them, over and over. need a sound design, good execution, good commissioning, and ongoing This is why Xstrata Technology provides support after commissioning. You need a technology “package”. Just as a car to operate and maintain your plant in is more than an engine, technology is the long run, long after the construction more than a single piece of equipment. company has left.

A number of large nonferrous mining operations in the world are still in business today largely because of the commercial benefits that resulted from applying these technologies. ISASMELT and ISA PROCESS technologies are marketed worldwide by Xstrata Technology, a division of the Xstrata plc group of companies, which was formed upon Xstrata’s takeover of MIM Holdings Limited in mid 2003. Xstrata PLC is a diversified international mining company and has operations in Australia, the United Kingdom, Germany, Spain, South Africa, Chile, and Argentina with around 20,000 employees worldwide. Major products are copper, lead, zinc, silver, coal, ferrochrome, and ferrovanadium. In addition to these commodities, an integral part of the group is their independent process technology business – Xstrata Technology. Xstrata group companies have a long record of developing process technologies for in-house use and for sale to external clients. 2.0 ISASMELT™ TECHNOLOGY ISASMELT is a modern bath-smelting process for the production of non-ferrous metals. -

Energy Consumption in Copper Smelting: a New Asian Horse in the Race
JOM, Vol. 67, No. 5, 2015 DOI: 10.1007/s11837-015-1380-1 Ó 2015 The Minerals, Metals & Materials Society Energy Consumption in Copper Smelting: A New Asian Horse in the Race P. COURSOL,1,5 P.J. MACKEY,2 J.P.T. KAPUSTA,3 and N. CARDONA VALENCIA4 1.—5N Plus Inc., Montreal, QC, Canada. 2.—P.J. Mackey Technology, Inc., Kirkland, QC, Canada. 3.—BBA Inc., Montreal, QC, Canada. 4.—Deltamet Consulting, Pointe-Claire, QC, Canada. 5.—e-mail: [email protected] After a marked improvement in energy consumption in copper smelting dur- ing the past few decades, technology development has been slowing down in the Americas and in Europe. Innovation, however, is still required to further reduce energy consumption while complying with stringent environmental regulations. The bottom blowing smelting technology being developed in China shows success and promise. The general configuration of the bath smelting vessel, the design of high-pressure injectors, and the concentrate addition system are described and discussed in this article with respect to those used in other technologies. The bottom blowing technology is shown to be operating at a temperature in the range of 1160–1180°C, which is the lowest reported temperature range for a modern copper smelting process. In this article, it is suggested that top feeding of filter cake concentrate, which is also used in other technologies, has a positive effect in reducing the oxidation potential of the slag (p(O2)) while increasing the FeS solubility in slag. This reduction in p(O2) lowers the magnetite liquidus of the slag, while the in- creased solubility of FeS in slag helps toward reaching very low copper levels in flotation slag tailings.
