rpg said:just to add my 2 cents, these numbers are from a research on 1999-2003 cell phones and the percentages account for the full weight of the phone including battery. I've seen phones go for over $1 each on ebay, not sure if they are worth that much. Boards at a $1 a piece maybe, as they are only about 15% of the total phone weight. Interesting research artice http://www.bren.ucsb.edu/research/documents/cellphonethesis.pdf

Precious metals, specifically gold (Au), silver (Ag), and palladium (Pd) contained in cell phones have been the major economic driver for recycling industry despite the small mass contained per unit. However, since cell phones contain a mere 150grams of gold, 2,000grams of silver, and 100 grams of palladium per ton, any added-value in the material recovery of these elements can only be possible by the collection of a large number of cell phones. (Takahashi, 2004)
(note that I believe these numbers are for 'working', i.e., with battery, phones)original cell phones were approximately 5kg and have
shrunk to their current weight of about 100grams.
