Metalliferous minerals play a central role in the global economy. They will continue to provide the raw materials we need for industrial processes. Significant challenges will likely emerge if the climate-driven green and low-carbon development transition of metalliferous mineral exploitation is not managed responsibly and sustainably. Green low-carbon technology is vital to promote

Minerals mean natural resources lying underground, on land in the form of natural concentrations of minerals, useful mineral substances in solid, liquid or gaseous forms, which are exploitable at present or in the future. Minerals or mineral substances lying at dumping sites of a mine, which can be re-exploited later, are also minerals. 2.
