Welcome to the forum,
If you think you can come here and not know anything about refining and earn $500 a week, good luck. If it were that easy we would have a million members. We have members who have turned a hobby into a profession but it took hard work and time to source the material to do it. Most use their hobby to hopefully finance itself, and accumulate precious metals in the process. But most are not earning at the $500 a week rate. I wish it were true, but I don't want you to have false hopes.
Basically everything you need to learn to refine precious metals is here for you to learn. And there will also be support if you have questions. Just don't quit your day job.
