chinese player apologize for poor english
In order to get 4 basic minerals of angel module.
First of all, i need lots of sulphuric acid.
However, sulphuric acid does not know how to produce.
Previous versions can wash coal and get sulphur containing wastewater.
But now there are no suitable recipes.
So I can't produce basic minerals.

Hi, I'm japanese player, speaks poor english too.
Have you ever try "Washing 1" technology's Heavy Mad water processing?
I use it at first step.
At next, I reseach "Sulfer Prosessing 3" technology in high priority. Sulfur Air Scrubbing is more better solution to get Sulfuric waste water.
