First Time Gold Recovery using Acetic Acid and Hydrogen Peroxide.

Hey guys first post here. So I've recently ran my first gold recovery. I took apart cell phones, computer boards, ribbons, etc. I combined them with 30% vinegar and 3% hydrogen peroxide and some sodium chloride. I let it sit for 10 days while stirring it often..
I ended up actually removing most of the gold flakes, but my issue is, there's so much residue mixed in with the gold, it's hard to isolate it. I just filtered the liquid, and there's quite a bit of gold mixed in with the "sludge. Unfortunately I can't post images yet, but.. imagine a coffee filter with a bunch of dirty residue on it, mixed in with very small gold flake.

My question is, how do I continue to refine and isolate the gold from this point on?

Thank you guys in advance. Looking forward to your help.
