Aproximations please?

Hello all,

Some newbie questions here, I couldn't find the answers on the forum (I may have missed them though)

1) If you had to purchase your scrap gold (strictly trimmed fingers for these questions), what would be a reasonable price per pound?

2) Supposing the gold content on these fingers was average at best, how many pounds would you need to recover one ounce?

3) If I had one ounce of refined gold powder and melted it, how much weight would I loose? OR would it not loose weight? (Does this change the answer for #3?)

I believe I answered my question with assistance from Catfish, see the Au Calculator here:

Thanks for sharing the calculator! I am a newbie and this will help me alot. I also like working with excel using formulas and such. I may tweek the arrangement a bit, but I really appreciate the time you took to create this calculator.

Hi Guys:

We have had many questions in regards how to determine the amount of gold or silver is in electronics scrap. There have been many white papers written on the subject and a couple by myself. I have discovered a website that you can punch the numbers in and the site will compute the exact amount of gold or silver you can expect for the E. scrap. You just have to have the basic numbers, like the size of the gold plated items, thickness, diameter, length and width and etc. The only draw back on using this calculator is that you have to convert the results from Avoirdupois (ounces) to troy weight numbers like grams or penny weights.

I have made many sanity checks on the calculator and they are very accurate. It sure does simplify the math and comes up with the same result.

The site is:

If you have problems on converting the resultant numbers for Avoirdupois weights then you may want to go to this site and it can convert your numbers.

I hope this helps.
