Here this should help.
1.) You don't have any platinum ore you will recover from home and make money at doing, so you can stop wasting your time with that. There is nothing you will be able to do on a shoe string budget to get platinum from Arizona soils unless you bought a metal detector and someone lost a ring.
2.) If you do have copper ore, focus your efforts on making a pile of it and sell it to a company as local to you as possible that processes it. It's not worth working on a small scale and you will not make money, just amounts of waste that that you will be legally compelled to deal with at some point in the near future. When they go to sample your pile, make sure a third party representative that does that sort of thing is there and if it turns out that there are large amounts of gold after a scorification and fire assay of the sample splits taken, then insist on getting some payment.
Short answer --- NO
Unless the gold is in the form of actual metal there is no why to separate just the gold from the rest of the rock
Because the metals (copper/gold etc.) in the rock (ore) are in the form of sulfides - you need to first reduce the sulfide (break the chemical bond that makes them a sulfide) to actual metal - the metals can then be recovered (smelting or leaching) from the ore --- the recovered metals will then be an alloy of copper/gold etc. - the metal alloy then needs further processing to separate the different metals in the alloy
On a small scale this is a time consuming & complicated process that will always cost more then you recover especially if the primary metal is copper

Nountaineer, if you were paying attention to others' previous posts, what people who know more than you were trying to tell you is it doesn't matter if you're interested in processing the copper--
it has to be processed to get the gold, silver and perhaps, just maybe the platinum contained with the copper.
