I am a Junior in High school, and we were given a task to find the cheapest, cost and environmentaly safe way to extract silver from a mixture of Iron, sulfer, and Silver nitrate, all of equal values, equalling a total of 10 grams.... Please help~!

I'm not sure about this. It may b too late neway if u've had to finish it or something, but metal displacement might work.

If the mixture is in solution, i think you can put in a metal of a higher reactivity (eg: copper) and it will displace the silver from the silver nitrate leaving it on the outside of the copper. it can then be removed and melted.
I don't know if this will work because we only did it with the silver nitrate solution, not with the sulphur or iron.
