Some Gold Tidbits and Where to Find Them,

Mech.

Anything on the value of an individual pin in the first pic ? The prices for nickel pins plated with gold at 5 ppm seem to be all over the place.

I just keep adding to the OMG jar.

In regard to the pins ... it was sort of a leading question. I've been harvesting the pins for awhile and have a couple pounds put up. It's quite labor intensive and it takes a lot of pins to add up to a pound.

My best understanding so far is that they are generally gold plated nickel. The average plating is put applied at five parts per million by weight. The older,richer, plating with that deeper color was applied at ten parts per million.

Maybe there's an error in my reasoning somewhere but when i ran the numbers yesterday it came up like this:

For every pound of pins you come up with five millionths of a pound of gold .... about .78 cents.

There would actually be more value recovered in nickel.

When you balance the effort it takes to make a pound against the value recovered you have to decide if the juice is worth the squeeze.

If it isn't worth doing and you decided not to do it .... that would free up your time to do something else that's more profitable.

Just a thought ... somebody that's refining pins would probably know better about the yields.

That part in the mouse. It can be broken down a bit furthur. Its a image sensor and looks quite pretty. It has Gold wires on it, just like a LED, but about 6 or 8 of them.
Actually image sensors are great Gold wires sources.
Those camera ones, Office photocopy machines have a larger rectangle one, also very nice looking.
And computer flatbed scanners have a long strip one with over 250 Gold wires in it.

Other places I look are contacts on relays, the little block on the boards, normally blue or black.
Switches, the ones in microwave doors ( mostly Copper/Silver or Silver) and the same switches from dishwashers tend to be Gold ir Gold plated.

The little switches from behind tapedeck units for switching the FF and Rwd motors on and off. Simikar switches from other places.

Any switches from high quality electronics. The little block ones with a bunch of switchs on it are great too.
Mostly the Gold wires are exposed so I keep the strip in its black plastic casing support bar.

Is gold located on "Diabetic Meters" pcb?

I've been seeing some in diabetic meters and pedometers. Small boards but very evident gold.

It's hard to tell if it's worth the hassle. Lots of little screws and the boards weigh almost nothing. Plus, the gold looks a little white, like it's a thin plating. But once you pull off the battery, it's a very clean board.

I put the units, whole, aside, for now. There aren't many of them and they don't take up too much space.

Thank You for the information, it helped me out. : )
