Indium is a rare, post-transition metal that is widely used in modern technological applications such as liquid crystal displays and photovoltaic solar panels. It is one of a number of so-called "e-tech" elements whose supply is considered to be insecure. Currently very little information exists on the behaviour of indium in geological and environmental systems. The lack of background data inhibits the development of an understanding of the fractionation mechanisms of the metal in geological systems and the natural environment. Little is known about the general background concentrations in different geological terranes, the conditions that lead to ore formation, the metal fluxes into the environment, the environmental sinks and reservoirs, and the bioavailability and ecotoxicity of the metal. This lack of knowledge represents a major impediment to the effective prospecting and extraction of indium. This project will identify and address the principal gaps in our knowledge of the geology, extraction and environmental dispersal of indium. The ultimate goal is to facilitate the development of robust models for the geological reservoirs of indium, to establish the principal transfer mechanisms between these reservoirs, and to enable for assessments of environmental risks, pathways and sinks. |
