Outline of Research at the Start	The present project deals with the development of a further novel and fully sustainable highly efficient green recovery process for gold in an eco-friendly hydrometallurgy system by utilizing the non-valuables (i.e., tailings) from mines, and intends to develop technology by applying the most of decomposition reactions that occurs during the recovery process.
