Well, I now know copper concentrate is massively moved via rear loaded containers, lots of special copper containers which are different, but standard container wins.

Which sort of makes sense given the whole logistics method with sealed all but rear being a massive industry standard. Just maybe they only fill to where a dump can dump , so to speak. I do recall someone telling me years ago a half full container will always be cheaper than a bespoke method.

Experts fall in line.
