A Lab Study Of Mineral Scale Buildup On Line And Traditional Pe Water Pipes For Acid Mine Drainage, Amanda Pezzuto, Emily Sarver

Journal of Sustainable Mining

Plastic, especially polyethylene (PE), pipe material is increasingly used in mining applications due to its inert nature, flexibility, low density, and low cost. Though resistant to chemical corrosion, it is susceptible to abrasion. To combat this problem, an abrasion-resistant liner is in development. However, it is not yet known how the liner will perform with regards to other common problems that affect pipe systems, such as mineral scale buildup. In mining applications, scale buildup occurs due to the very high contents of suspended and dissolved solids in water or slurry. For example, in systems transporting raw or treated acid mine …
