Abstract

Steel pickling sludge disposal lead to the pollution of soil and groundwater. The method of sludge mixed with low-grade lateritic nickel ore was proposed to either recover the valuable metals such as iron, chromium, and nickel, and the tail was disposal environmental friendly. The technique of XRF, ICP, XRD and EDS were used to characterize the chemical composition, mineral phases and physical chemical properties. The carbon was used to reduce the compound of low-grade lateritic nickel ore and sludge. The temperature, ratio of ore/carbon and the capacity of sludge were investigated for improving to recovery metals. The results showed that the products were separated into 3 types. The metals were enrichment in Fe-Cr-Ni alloy particle and concentrate. The mass content of Cr and Ni in tailing was low than 0.1% which could be safe disposal.
