Extracting elemental metals from urban repositories

The overarching term “Urban Mining” is used in the professional world and stands for increasing readiness also in the field of assuring a supply of raw materials to describe concepts for developing ways to extract valuable materials from existing waste storage facilities in order to feed these back into the production industry. MME Engineering’s approach to this topic lies in hydrometallurgical concepts. Old repositories which in some cases store several different metals, are transitioned to the hydrous phase by means of chemical decomposition.  By means of steps of separation, one can extract elemental metals.
