Yes, it all depends on the cost.

What your analysis misses is a lot of the previous cost was digging the ore out of the ground and processing it down to the tailings size. There can be a lot of cost in that process.

Treating tailings is generally much cheaper than digging the ore out and crushing it to sand size to begin with.
