The goods are electronic equipment that has become waste, ironically this type of waste is very rapid growth. Even United Nations Environment Programme (UNEP) United Nations recorded electronic waste in the world grew 40 million tons per year. It is due to electronic goods has operational life and also human consumable attitude that always wants new products.
But from harmful waste to the environment, there turns out that there are valuable materials besides metals and plastics, among others silver, paladium, platina, routenium, even gold.

The city miners are looking for electronic waste such as television and computer hardware, the parts of the components sought primarily are the connector parts and contacts on the circuit board as it contains gold that serves as an electrical delivery component on low voltage devices or low currents. Data from the Wired magazine shows that one average mobile phone unit is estimated to contain 0.2 grams of gold, generally there is on the SIM card, logic board and components behind the LCD screen.
A city miner in Jakarta tells that they are looking for waste in waste disposal, come to a collection of rongsok goods or participated in auction of electronic items sold by a company. After that they separate the existing components of the golden content.
Gold is taken by burning components containing gold, burned to separate from plastic components, after which it is processed using chemicals namely hydrochloric acid, hydrogen peroxide and mercury. After successfully striped the golden part then melted with chemicals in the form of ulcer. To get 99.9 percent pure gold should be done the purification process using hard water fluid to separate other metal elements that still stick to the gold.
