Talkin’ about conflict minerals:
Congo is a home to some of the largest reserves of gold, tin, timber, diamond, copper, cobalt, tungsten and tantalum – to name but a few – in Africa. The most lucrative of all is columbite-tantalite, better known as coltan: a dull metallic ore that stores electricity and makes our mobile phones vibrate.
Sigh. The tantalum comes from the columbo-tantalite (not columbite-tantalite) . Our writer here is showing that she’s not quite up with what is happening, isn’t she?
