CIL Tank Preservation
After 1 year of operation, CIL process tank inspections revealed higher than expected wear and pitting corrosion. ICE specified liners and oversaw the project to line the tanks and increase service life.
Challenges:
- Entrained solids plus chlorides
- Unlined CS process tank x 6
- 1 year in operation
- Pinhole leaks from erosion-corrosion
- Pitting up to 1 mm depth
ICE impact:
- Analysis of risk vs. operation
- Specification of internal liner system
- QA/QC design and oversight
- Working well after 1 year in service
