  • Biomining: metal recovery from ores with microorganisms

    Biomining is an increasingly applied biotechnological procedure for processing of ores in the mining industry (biohydrometallurgy). Nowadays the production of copper from low-grade ores is the most important industrial application and a significant part of world copper production already originates from heap or dump/stockpile bioleaching. Conceptual differences exist between the industrial processes of

  • Mining Methods 101: How the Metals We Need Are

    06/07/2016· Once the ores have been excavated, the metals themselves must then be extracted from the ore, a process that depends on the metals’ reactivity, according to BBC.
