What are Tailings? Tailings are a by-product of mining. After ore containing an economically-recoverable commodity is mined from the earth, that commodity is extracted in a processing plant or mill. After the commodity of value is extracted from the ore material, the resultant waste stream is termed "tailings".

I. RECYCLING IN CONTEXT the amount of indium that could have poten- tially been recovered from zinc-bearing ores in 2010 is 1454 t. The USGS reports that 574 t of in- dium were produced globally for the same year (Tolcin, 2011). In other words, a third of the total indium currently available from zinc refineries is not recovered.
