Need help with separating my gold, platinum and copper dust

I have gold, platinum and copper dust, I was wondering if a shaker table would do the trick

that one to be more specific. as I explained I have about 500Lbs of this product. each grain is about the size of baking flower and I do not know anything about chemicals what so ever. I called many refiners and I can't get a straight answer from anyone. I just recently got ripped off by a gold agent who said 60 lbs was worth 500$ when he gave me 200$ a pound when I first gave him 2 lbs. and other refiners want to take 50% of my gold and platinum and not pay me a dime for my copper, so if someone can tell me if this shaker table would be good I would love you forever lol if not what else can I do? keep in mind my product consists of 98% copper 1% platinum and 1% gold.

thank you

The specific gravity of each metal is close enough to the others that I do not think that a shaker table would separate it very well. 50% nitric acid will dissolve the copper and not touch the gold or platinum. Once you get the copper removed, a jeweler that uses white gold would probably give you a reasonable price for it. I doubt if anyone will give you more than 80% of spot for it. The uncertainty of the true purity of the material is not worth saving a few dollars.
