We believe that a solvent-free, modified, polyamine-cured epoxy with an anti-abrasive filler is a perfect solution.

We usually work with solid polyurethane linings (12 mm thickness) for the interior of pipelines with copper slurry tails and concentrates. You can see some solutions in www.acotec.cl.

As far as I know, the answer is an abrasive-resistant epoxy. Some phenolic type with hard filler will also fulfill this purpose. However, if the flow of material is a concern, a low-friction coating like fluoropolymer is better.
