Hello everybody, best greetings from Middle Europe:
Two months ago, I began the hobby of alchemy. My old laptop was battered in little pieces. In the meantime, I read and saw many contributions and films in google, youtube, e-books etc.. Now, my girlfriend is angry and forced me to stop surfing in the web during the night. Nevertheless, my collection of material grew.
There are 25 PC-motherboards mostly from the early 90s (inclusive 11 CPU's with 0,1-0,3 gram each) and also 35-40 little boards (green color) mostly hard drives and cards from the 386, 486, Pentiums plus another newer electronics. Thanks for the presents from neighbours, friends and friendly people.
In two weeks, I will bring the stuff to the country. A city apartment would not be the best place.
My equipment:
1 litre HCL, 1 litre H2O2 (Peroxide), 500mg Borax, 500mg baking soda, a gas-burner from the do-it-yourself superstore + melting pot, hammer, chisel, screw-driver und pliers, gloves, gas mask, goggles, leather apron and dishes.
My goal:
One piece of 8-18 carat Gold and one piece of 30-50 % Silver with 5-15 % Palladium
The plan of the easy and fast method:
1. Cutting the gold fingers and throwing them in HCL/H2O2 (ratio 3:1 or may be later 1:1)
2. Chopping the IC-Chips and MLCC's off with hammer and chisel
3. Soldering off the golden pins from motherboards/CPU's and putting them in HCL/H2O2
4. Heating the IC's and CPU's in tin foil and breaking them in little pieces; putting them in linen and powdering them with the hammer (this process need something like an anvil or other hard base). The powder can be sorted and washed. A gold pan would be the best, but I will use some dishes from the kitchen. The yellow rest would be collected.
5. Same process with the MLCC's but without the washing.
6. The foils and sticks from step 1 and 3 will be filtered (old socks or coffee filter) and collected. Baking soda will neutralize the acid. (There are special dumps. It cost nothing to bring them.)
6. Giving one handful of Borax in the melting pot.
7.Melting of the gold material (one piece of 8-18 carat gold)
8.Melting of the MLCC-powder also with Borax (one piece with silver and 5-15 % Palladium)
9. Drinking a Tea, Coffee or Beer and laughing about the result.
Is this a good way? How much can be recovered?
