Not necessarily. A simple aeroshell and a ballute can suffice for that, assuming the return vehicle doesn't have to transport people. It could end up being cheaper than air freight, especially if the heat shields are also manufactured in space. I don't think space mining is ever really going to catch on since there will always be a competitive as well as political advantage to ground-based operations. Energy and certain rare resources have the virtue of being scarce enough that you won't always be able to find them on Earth anyway.
