As Demon3 says, contact a reputable supplier with a lot more details than you posted here, like processing method, design details, environment for use, consequence of failure.

That said PE100 from a reputable manufacturer can be relied upon. Some of the other grades have regrind content that could have had the stabilisers and dispersants burnt up in the first extrusion.

Degradation of the surface will result in a poor appearance (not a problem in mining applications) and micro-cracks at the surface which will reduce impact and fatigue strength. If the part is designed with enough reserve strength this may not be a problem.
The level of protection from carbon black depends on particle size, amount of carbon and quality of dispersion.
A UV stabiliser will protect the surface.
