According to United States Geological Survey (USGS), indium ranks 61st in abundance in the Earth’s crust at an
estimated 240 parts per billion by weight. This makes it about three
times more abundant than silver or mercury.
Currently silver is about US300/kg and consumption is comparable to indium.
The current high price of indium is caused by market speculation.
Indium occurs predominantly in the zinc-sulfide ore mineral,
sphalerite. Once zinc price stabilize from falling, indium production
would rise accordingly then its price would come down to where it
should be.
CIS solar cell contains about 3g of indium per M2.
