The ash may be crushed to increase metal liberation. It is then sized, demagnetized (ferrous metal removal) and presented to eddie current separators for recovery of HNF and LNF metals. Sometimes, hand-sorting or sensor-sorting is applied for oversize streams or the recovery of stainless steel…

Warning: Molten metals form alloys with platinum very easily. This can result in a hole being formed in the bottom of the crucible. And soot (or carbon black) is a so-called platinum poison in a non-oxidizing atmosphere. In the 1600°C furnace, a crucible can stick to the cru-cible holder, which is also made of platinum. This can be prevented

November 16, 2009. Authored by Alana Fossa. The hot-dip galvanized coating is primarily comprised of zinc and zinc alloys, but is sometimes placed in contact with different metals including stainless steel, aluminum, copper and weathering steel. When two different metals are in contact and exposed to a common electrolyte, one of the metals ...

For example, the MSWI bottom ash produced by the incinerator at Amsterdam contains materials such as non-ferrous metals (2.3%), ferrous metals (8-13%), gold (0.4 ppm), silver (10 ppm), stainless steel (0.1%) and minerals that can be converted into building products such as aggregates utilized for concrete, asphalt, etc.

The most common is magnetic induction separation by electromagnetic sensors that can identify all kinds of metals, including stainless steel, in particles larger than 4 mm. Both the recovery rate and grade can exceed 90 %. The sensor is placed under the conveyor belt, where the transported IBA must be spread out in a thin layer.

Noble metals are stingier with their electrons, whereas base metals give away their electrons more easily. How easily a metal gives up its electrons is what determines its place on the galvanic scale. So, in the same environment, a metal like aluminum will give up its electrons more easily than a metal like stainless steel.

Bottom Ash (MWI-BA), only few address the technical and economic aspects of metal extraction. This document strives for filling the gap. Although the recovery of scrap metal from BA has a long history, the dawn of modern BA processing may be placed in the 1990ies. Three factors have greatly contributed to its early proliferation since:

This material has a non-ferrous metal content of between 40% and 65% with the balance being aggregate and dust. Using the latest separation technology, including eddy-current, induction and X-ray sorting, the dust and aggregate is removed and individual fractions of aluminium, copper, brass, zinc, stainless steel and precious metals are recovered.
