gold recovery techniques

Gold, in particular, is easily extractable in these devices, so much that it is possible to extract more gold per ton of cell phones than per ton of actual ore. Per ton, gold ore yields approximately 5 grams (0.18 ounces) of gold. Per ton of recovered cell phone circuitry, it is possible to yield up to 150 grams (5.3 ounces) of gold.
