Australian Team Develops Mining Technique That Uses Magnetic Fields Rather Than Digging
Scientists from the University of Exeter, the Technical University of Denmark, CSIRO (which is the national science agency in Australia) and the University of Western Australia have designed a new mining method that extracts minerals from hard rock ore using electric fields. The method could replace the conventional digging technique, which causes significant effects to the environment. These include biodiversity loss, formation of sinkholes, deforestation, erosion and the contamination of ground, soil and surface water. Currently, methods of digging are utilized in 99% of activities involved in mining, which often leads to large quantities of solid waste and considerable environmental…
