Since I'm having difficulties understanding ratios using pennyweights, pounds and gallons I decided to come up with a rounded ratio of Ferrous sulfate, water and Hydrochloric acid per gram of gold using my native metric system.
For each 1gr of expected gold: 5,5gr FeSO4 + 11ml warm H2O + 1,7ml 37% HCl.
Those numbers came up from Hoke and 4metals's "ferrous sulfate quality" post and I'm just wondering if this ratio is about right. From what I can understand, once prepared it cannot be stored, please correct me if I'm wrong in any of the above.
It was a little hard to find this little info in forums because FeSO4 aka ferrous sulfate aka copperas and HCl aka hydrochloric acid aka muriatic acid giving me too many possible combinations of keywords to use but I still went trough hundreds of posts, not complaining even because I've found many other useful info's like reduction agents chart and few other very interesting threads about it 8)
Thank you!
