Subject: E-waste mining is a process where valuable materials such as gold, copper, iron and
plastic are extracted from the circuitry of computers and cell phones, by using the same
techniques that miners use to process metal ores.
One tone of scraps from discarded computers contains more gold than can be produced
from 17 tons of gold ore. Mumbai, alone throws away 19,000 tons of electronic waste a
year, excluding the large e-waste imports from developed nations through its port.
E-waste is often richer in rare metals than their ores, containing 10-50 times higher copper
content than copper ore. A cell phone contains five to 10 times’ higher gold content than
gold ore. Sunder Thadani. 20170605.
