Welcome to us.

Usually we use either a Copper Chloride aka AP leach or a Nitric leach to take out the base metals, then refine the Gold.

Anyway pleas study first.

We ask our new members to do 3 things.
1. Read C.M. Hokes book on refining jewelers scrap, it gives an easy introduction to the most important chemistry regarding refining.
It is free here on the forum: Screen Readable Copy of Hoke's Book
2. Then read the safety section of the forum: Safety
3. And then read about "Dealing with waste" in the forum: Dealing with Waste

Suggested reading: The Library
