HF, Jivolite mining

Re: HF, Jivolite mining. Without modules, fluorite ore from waste water doesn't actually cover your mining costs from infinite ore mining. Each ore costs 10 acid and produces 25 waste water, which turns into 2.5 acid. So it lets you recover 1/4 of your initial acid investment, but that's all. Also, of course, any crushed ore that you use ...
