Dear Bill:

The cheapest way to make something isotopically pure is to add a halogen to the silicon converting it to a gas and then use a gas centrifuge to separate the isotopes. They are long lived, easy to run, do not use much power, and would be cheap compared to other methods. Then you simply strip off the halogen away chemically and you have you pure Si-28.

Gas diffusion is an old technology used in Nuclear weapons plants to make pure U-235. Now they use gas centrifuges instead getting higher purity, higher production, and lower footprint at a much cheaper cost.
