I’m so sick of this, to make fertiliser from brown coal...
Grind it to 80 mesh,
Make a watery slurry
Heat to 60 to 80 c
Add some,
Sodium hydroxide
Add hydrogen peroxide
Or any consumed by process oxidiser
Pump some air through the mix
Filter and ph adjust
Voila! A liquid fertiliser business.
This is so drawn out it makes me sick watching it.
