Is presence of free ammonia have impact on ferrous sulphate ?

I would think that ammonia would have little impact, but I am not 100% sure on that. My experience with ferrous and cyanide destruction comes from my time on the Gold plants in South Africa, where we made a scrap metal/sulphuric acid ferrous plant and dosed the tailings before it wa sent underground in a backfill operation - so no ammonia involved at all.

The best would be to run a small test to establish your ferrous dosage requirement and at the same time undertake observations of the impact of the ammonia, if any, on the destruction of cyanide.

Good luck with this interesting problem.
