Rock dust is likewise being looked at with interest in Australia -- another
very old, exposed surface almost devoid f fertile top soil. However, rock
dust etc is 'chemicals' too -- all matter is. It may be less processed and
'artificial' than other refined fertilisers. 

What information do you have on where and how your mineral supplements are
mined? What is the environmental and social justice impact at that end?
I've not seen any information on this, so am still unsure how 'sustainable'
rock dust is as a fertiliser.
