51317--9649-Corrosion Management Planning Lessons for Seawater Conveyance in Mining

This paper will present a case study, which will outline the challenges and lessons learned with corrosion in a Mine project in Chile where the internal corrosion of the seawater conveyance line caused a number of technical, project schedule and budget impacts during the commissioning stage of the project.

Mining is one of the few industries that can use low quality water for processing. Where mines are located in arid climates such as the Atacama Desert in Chile there have also been increasing regulatory pressures on the use of fresh and brackish groundwater sources. In the last decade this has resulted in mines moving towards the use of seawater to supply their operations which often has to be transported 100’s km inland from the coast in conveyance lines.The corrosiveness of seawater introduces an increased corrosion risk for these projects a risk which is currently not alwaysmanaged in a proactive way from the design stage and therefore hassevere implications for operation and maintenance performance over the life of mine.This paper will present a project case study which will outline the challenges and lessons learned for a Mine project in Chile where the internal corrosion of the seawater conveyance line caused a number of technical project schedule and budget impacts during the commissioning stage of the project. These lessons learned are used to highlight the opportunities for evolving engineering design to incorporate corrosion management from the beginning of a project and allow this specific issue to be controlled in the most optimal way.

Key words: mining, seawater, water conveyance, corrosion design
