Approx Value of Pentium Pro Chips

the assay is only as good as the man (or woman) that performs it. Aside from numbers being skewed, there is gold lost in the recovery process as well as all of costs associated with recovering the metals.

it only takes 5 pentium pro chips to equal 1 pound.

Just for your info they sell on ebay for about 30-40 per processor.

OK let me redo your numbers as I know them.

31.1 grams per troy ounce for gold purpose
454 grams per US pound

This website http://www.scribd.com/doc/28911037/G...t-in-CPU-Chips says that a pentium pro chip is 87grams.
I will use ewasteds value of $105 per pound If you have a buyer at $175 I would like to know who that is. I have some CPU's to send them.
So we take $105 and devide that by 454 grams and get $.23 per gram.
Then we take $.23 per gram and times that by 87 grams per chip and get $20.01 per chip.

At 87 grams per chip it takes 5.2 chips to make a pound.

Hope this helps

As he said is right. To refine them can be costly due to the fact of the glass and trying to recover all the gold in that amount of weight takes a lot of acid.

He has found when he crushes them into large pieces he gets .3g and smaller pieces he gets .5g He also reprocessed the left over ceramics from some old ones and got about the remainder if I remember correctly to make the .3g ones up to just under .5g.

Hmm...I need to get back over onto that site and give that thread a good read.

In NZ, I can't find a escrap buyer. There are probably some, just not close enough.

So I'm going to have to refine the gold myself & I need a rough idea of how many computers I'm going to need to get 31 grams of gold.

At 0.15 grams per CPU, thats 207 Cpu's per Oz Gold.
I don't know what the gold content of the rest of the computer is, I'm expecting more than 0.15grams though.

At 0.3 grams per computer, thats still 100 computers, I have about 20 plus some odd finger boards as well.

Should I start work on the job with about 50 complete computers?

Precious metals such as gold are measured in troy weight. A troy pound is 12 troy ounces, and each troy ounce is 480 grains, making a total of 5760 grains to the pound of gold.

Most materials use pounds and ounces from the avoirdupois system, and such a standard pound is made up of 16 ounces, where each ounce is 437.5 grains, making a total of 7000 grains to the pound of feathers.

All this means that a "ounce" of feathers (or bricks, or lead) is heavier than a "ounce" of gold.

If an ounce of gold is 480 grains and feathers are 437.5 grains isnt an ounce of gold heavier?

I think he meant pound instead of ounce. Makes more sense to me,,,

Yeah he ment to say a pound of feathers weighs more then a pound of gold. thats why i tried to make the funny
