Step one, describe what you have done. Source of material, filtering, which acids you have used and so on. Without knowing what you have done it is hard to give good advice. If someone misunderstand what you have done you could even get bad advice.

The better you describe your situation, the better advice you will receive.

when your in this much doubt, add to your solution a heavy piece of copper and cement all the values out of solution. give it a few days. rinse whatever is left of the copper back into the solution and let everything settle until the solution is clear. it will still be dark, when i say clear, i mean not murky. siphon or draw the solution from the powder and rinse the powder with water. re-dissolve the powder with hcl/Cl (hcl/bleach). let the chlorine evaporate overnight and drop the gold with SMB.

Read Hokes well before trying Aqua regia.
