Either way, you're going to have to mine the raw materials, and I don't see how it would be more cost effective to mine, then manufacture a proppant (using a lot of energy to do so) vs. simply mine sand and ship it by rail.  Ceramic proppants are only superior in cases of deep, high pressure applications, where the rock pressure would crush sand.

Still, there is a drop in the sand mining activity.  There must be a reason.
