METGROW+ WP3 progress and WP3-WP4 cooperation meetings were held in Espoo, Finland, 2-3.5.2017. The two-day effort was given to the design of leaching and metal recovery technology combinations material by material. Building on the interactive feedback from participants, the result was a process map for METGROW+ materials. It includes existing metal extraction and recovery unit operations tailored for low-grade resources, as well as novel unit operations specifically designed for low-value materials. In addition, participants visited the laboratories and pilot facilities of VTT Technical Research Centre of Finland.
