Finally after a month and a bit I have finished processing the 50 pounds or so of gold plated AV cables ends that I was given.
What a waste of time. As you can see in the picture the gold should be pretty pure but only approx 1 gram once the filter paper is removed. The ends were processed in a sulfuric cell over the period of about 6 hours.
At first it looked there was going to be 5 or 6 grams of gold at least... there was lots of black powder in solution... Once it was put into hcl and bleach it turned out to be almost entirely copper chloride. (Grey fluffies)
So my advice is if you encounter this type of material. Dont waste your time.
