Silver makes the iPhone vibrate. Lithium batteries. there’s plenty of copper, gold, and silver in the wiring. Silver makes the iPhone vibrate. Lithium batteries.

The platinum comes from south African bushveld, South Africa. The gold ore comes from the Yanacocha Rock, Peru. The silver comes from the Cannington Rock, Australia. The copper comes from the Escondida Rock, Chile. “At the moment, there are no really good environmentally friendly methods available to mine and to recycle rare earth,” according to Swedish University of Technology prof Christian Ekberg. less than one percent of the precious rare earth used in today’s phones are recycled — even though we appear to be running out of good sources for these vital materials.

Mixing water or other contaminants with molten aluminum can cause explosions. Molten Aluminum is typically handled at 1300-1450 degrees Fahrenheit to avoid premature solidification. Explosions can also occur in the aluminum scrap remelting process due to moisture and contamination in scrap.

Local environmental activists have claimed that mining operations, which use large quantities of a dilute Cyanide solution, have contaminated the water sources, leading to the disappearance of fish and frogs, illnesses among cattle, air pollution, and loss of medicinal plants. An environmental audit by the Colombian consultancy firm Investec S.A. (Ingenieros Consultores: Auditoría Ambiental y Evaluaciones Ambientales de las Operaciones de la Minera Yanacocha en Cajamarca – Perú 2003) found some water contamination above permitted levels and recommended improvements to Yanacocha’s environmental management practices.
