Use KClO3 instead of NaClO3 as the first is much easier to separate due to its low solubility in water.

Brilliant suggestions metalresearcher.
Curious about one thing though. Why do you want him dead?

I would be surprised if it wouldn't simply oxidize back to CaSO4.
As for aggressiveness, rapid decomposition seems to depend on transition metal contamination (besides reaction energy already). Gypsum should be
fairly pure if it's white, but even off-white sand can contain a significant amount of FeOx and such.

Metalresearcher, you obviously didn't notice my other thread concerning about evaporation. One can churn up to 30 liters of concentrated sodium
chlorate solution and evaporate off the water within couple of days and make a final drying phase in oven at mild temperature to obtain quite pure,
technically anhydrous NaClO3. But anyway, I still strongly think that aside from reacting CaS with CaSO4 to produce CaO and SO2, chlorate method would
be quite wasteful.
Btw, check out ebay and other marketplaces for chinese ozone generators. As we speak, one can make sulfuric acid directly by bubbling ozone through
the tank containing SO2.
3 SO2 + 3 H2O + O3 → 3 H2SO4
This is quite an interesting since cheapest ozone generators produce several dozens of grams of ozone in an hour and with this reaction, 20% solution
of SO2 will yield 40-60% of H2SO4 concentrations. It'd be probably possible to engage the reaction in gas phase, but then the efficiency will be
reduced by order of 2/3.

I wonder if monocalcium phosphate (or various poly- or metaphosphates) could be used to expel sulfuric acid and/or sulfur trioxide from calcium
sulfate. I guess that process would go at moderate temperatures (300-500 C) so that decomposition of sulfur trioxide would be avoided.

That should read; "milligrams per hour" . . .

There are several relatively cheap($20-30) ozone generators that can produce several grams of ozone per hour that can be found on ebay. Though
generators producing several dozen grams are significantly more expensive. I don't how long they can be run without overheating or
burning out though.

Better to use nitric oxides to oxidize the sulfur dioxide solution to sulfuric acid. A relatively small amount acts as a catalyst in the presence of
air.
