Pure Silver beads from Silver Nitrate (washings from parting of bullion assays)

My name is Steven & a plant chemist with a Gold mine here in Papua New Guinea. I have a bottle of AgNO3 which has precipitated out to the bottom of the bottle. The AgNO3 comes from washings when parting bullion samples. I'd like to purify this and re-use as silver beads by filtering out the solution and washing out the precipitate and heating to get the beads. Will the Ag beads be gold free and how will I know that this is gold free (test?). Would you have a simple solution for this?
