How to Estimate Gold Plating Thickness and Content

Here's an excerpt from a very good article:

The board is made over-sized, in order to provide electrical connections to the areas of the board that require plating. When the plating has been done, the "picture frame" is trimmed off with a die.

We used to hire cheap labour to cut off the gold plated areas of the picture frames with tin snips - the good offset type - you can buy them left or right handed. This will reduce the volume and weight considerably and will make the pile much less bulky. I, myself, have filled many barrels with just the gold portions, using this method - it's not so bad - wear leather work gloves. We then stripped the gold in a cement mixer with cyanide/peroxide.

Even if you don't process this yourself, by trimming it, you are putting it into a state that can be sampled and assayed, before having it refined. This is much harder to do with the picture frames, since many of them are different. You might also have a separate barrel for pale looking gold pieces.

If it is true immersion gold, it's worth about $.04 to $.05/square inch, max. Immersion...

This is the 2nd in an ongoing series of articles about my experience in the electronic salvage, recycling and gold recovery business. New installments, resources, how-to articles and news can be found at RecyclingSecrets.com

In my last post I began the story of how I got into the electronics, telecommunications and computer recycling / gold recovery business. I'll tell you a bit more about it here.

This seeming very small "tip" I got from the telecommunication workers turned out to be a virtual gold mine for me and my family.

Up until the time I met these guys, all of their scrap from upgrades and repairs to telecommunication microwave repeater stations in Nevada went into the local landfills. But, because of the upgrade across the state from tube type repeater radios to solid state, the amount of scrap was just too much to handle in this manner.

They told me that they thought the scrap was going up for bid and that I should contact the local office about it. I first, though, wanted to know what it was that I was bidding on. So, I went to the local office, told them of my intentions and they gave me a key to a repeater station and told me to take notes, samples, talk to workers - in short do whatever it took to make a reasonable bid that I could live with.

I headed to Nevada with my very used dodge van. I brought back samples of microwave tubing (beautiful pure copper rectangular tubing with brass flanges), large batteries for their backup power, gold plated attentuators, connectors and the like and many many photos of gigantic steel racks, radios racks of extruded aluminum, etc. etc.

Turns out that the company just wanted a flat per pound bid for everything but the batteries and then a separate bid for the batteries. Batteries at the time were very low in value and, in fact, becoming hard to find anyone who would take them for scrap at all. I asked if I could just bid on everything else and leave the batteries behind and was told no - it was all or nothing.

I was also told that I would probably be the only contractor to bid - they clearly were not interested in the revenue, they just wanted the stuff out of there.

I bid only 1 cent per pound on the batteries and just a few cents on the rest. I was awarded the contract. I still remember the local office guy saying, "are you sure you can handle this?" and me saying, "sure, no problem at all."
