Gold finger cards analysis result

[Anonymous]

I think the question of what was the make up of cards has asked quite a lot. Also what kind of cards are in the 50lbs of cards you have to smelt?

Göran did a great job of running some theoretical numbers earlier. I actually tried that myself too but I found too many variables based upon the types of cards.

Some pics would be really useful here.

Hi,

I weighed 1 kg of random gold finger cards, which I will post photos tommorow, and 15 of them made 1 kg, average weight for each card, with steel and aluminum removed, would be 67 grams. I smelted 4 cards, that is 268 g of cards, which produced 55 grams of metal, which would have 3200 grams of gold in one ton.

Here is a snapshot of sample boards which smelt metal showed 3200 ppm;
