What is HDPE Liners for Copper Leach Pads about?
This document discusses the compatibility of high density polyethylene (HDPE) liners used in copper leach pads with concentrated sulfuric acid used to pre-cure copper ores. Short-term laboratory tests showed HDPE experienced less than 3% reduction in tensile strength after 8 days of exposure to 96% sulfuric acid at 21°C. However, longer term testing is needed to understand ultimate property reductions at higher temperatures and acid concentrations that may occur in the field. The document provides interim g
