Renewable energy technologies for the 21st century: The Iberian Pyrite Belt as a possible supplier of indium

In the realm of the 21st century, mankind is forcibly turning to renewable energy sources, namely using PV technologies. To do this effectively it is imperative to understand the raw material limitations related to the mass production of these technologies as the manufacturing process is highly dependant on a constant supply of rather expensive, high-tech raw materials, e.g. Indium. The limitations imposed by raw materials supply is a catalyst for further mineral exploration in order to feed the hungry high-tech metal industries supplying, in turn, expanding renewable energy industries. One world class metallogenic province that merits investigation for its anomalous indium and other high-tech elements is the Iberian pyrite Belt, where the occurrence of Indium in the well documented Neves Corvo deposit. It follows that the other, marginal and now inoperative, deposits could also host accessory In and should therefore be investigated.
