And on this baking hot July day, when the temperatures approach 100 degrees, a geyser of water is shooting from a truck, in a never-ending bid to tamp down the dust.


From rocks to recycling: The life of an iPhone


Yesterday: We looked at the human toll of creating iPhones, and the activists pushing to improve working conditions.


Inside the rocks from this mine are rare-earth minerals, crucial ingredients for iPhones, as well as wind turbines, hybrid cars, and night-vision goggles. Minerals such as neodymium are used in magnets that make speakers vibrate to cr... [Read more]
