Large amounts of stabilized inorganic waste is often generated in the production of commodity metals. Conventionally, manufacturing is targeted at the recovery of one or two key elements as main products while the waste stream will gather all the other added-value chemical quantities. For example, the jarosite waste descending from hydrometallurgical zinc production includes silver, indium and gallium, which have become of increasing importance for e.g. new energy, electronics and touchpad applications. The jarosite waste heaps, while necessarily stabilized against weathering, appear typically as powder-like fines. A two-year research project is being conducted to recover the metal contents of jarosite waste by VTT and Aalto University.
