Advice on Fe / Ag refining in Montana?

A family member has a decent quantity of this recovered material from old xray film and developer. XRF testing of a sample shows 70-80% Ag & 20-30% Fe. Any suggestions on MT based home refiners and smelters or suggestions on simple ways to increase purity in a home shop? ​
