DESIGN, CONSTRUCTION AND START-UP OF THE ILO SMELTER MODERNIZATION PROJECT

摘要

Southern Copper Corporation (SCC) is one of the world's largest copper companies and is finishing the modernization of the llo copper smelter. A single ISASMELT™ furnace will start smelting 1,200,000 tons per year of concentrate at the end of 2006. Three existing Peirce Smith converters are being upgraded plus a new one for converting the matte to blister copper is being installed. Two new anode furnaces and a twin anode casting wheel have being operating since January 2006. This represents one of the main changes in the process because the final product of the smelter is now anode copper instead of blister copper. A new oxygen plant, acid plant, and others facilities are in the ramp-up stage. This environmental project will ensure that the new smelter will comply with the environmental regulations of Peru by the end of January 2007.rnThis paper summarizes the background to the modernization project, describes the different stages of the project including engineering, procurement and construction, describes the main areas of the new copper smelter and also the pre-operational testing, commissioning and start-up of them. This is a brown field project with a target of reducing as much as possible the production losses of the existing operation.rnThis paper presents the details of the development of the llo Smelter Modernization Project and explains the main aspects of the new facilities, the products to be obtained and the associated facilities for their commercialization, including a Marine Trestle for bulk acid exportation.
