chemistry lab

hi. im a Junior in high school and we were given a lab that i need help on.

we are going to be given 10 grams of an ore that contains a mixture of Sulfer, iron, and siver nitrate and we have to figure out how to extract pure silver on it...

but we only get once chance to do so so.... if we mess up were pretty much screwed.
so, if anyone knows how to go about doing that please tell me.
thanks:)
