Conclusions • Rising primary <strong>zinc</strong> prices have reached historic levels and are greatly impacting <strong>the</strong> raw material costs <strong>of</strong> <strong>zinc</strong> consuming industries such as galvanizing, die casting and brass manufacturing. • <strong>The</strong> quantity <strong>of</strong> <strong>metallic</strong> <strong>zinc</strong> contained within <strong>the</strong> waste materials <strong>of</strong> <strong>the</strong>se <strong>zinc</strong> processing facilities is extremely high, especially for producers <strong>of</strong> galvanized steel products. • <strong>The</strong> <strong>metallic</strong> <strong>zinc</strong> content <strong>of</strong> <strong>the</strong> waste drosses which are discarded <strong>from</strong> a molten <strong>zinc</strong> pot in a galvanizing operation may exceed 90%. • Unlike die casting and brass manufacturing, currently only a minimal volume <strong>of</strong> recycled <strong>zinc</strong> is directly returned to an industrial galvanizing pot. • Implementation <strong>of</strong> defined in-house procedures by galvanizing operations could help extract higher fractions <strong>of</strong> valuable <strong>zinc</strong> <strong>from</strong> <strong>the</strong>ir process wastes. • Utilization <strong>of</strong> a Metaullics MZR Zinc Recovery System may enhance retention <strong>of</strong> <strong>zinc</strong> inventories by providing an on-site secondary processing technique for recovery <strong>of</strong> usable <strong>metallic</strong> <strong>zinc</strong>.
