“…M ILLIONS of tons of dump copper slag quenched with water in metallurgical plant were dumped each year, which not only employed lots of land resources but also caused serious environmental problems [1][2][3]. Additionally it was proved that copper slag is a source of valuable metals including iron, copper, and zinc.…”

Iron, copper and zinc were separated and recycled from dumped copper slag using a carbothermic method in the presence of microwave irradiation. Iron in the form of fayalite and magnetite in the slag was reduced to metal iron while zinc was evaporated and captured as zinc oxide powder. Results indicated that metallization rate of iron could reach 91.38~93.45 wt% and zinc recovery efficiency was 90.5 wt% when the new methodology was employed, and that reaction temperature was 100°C lower compared to that of traditional processes, reaction time of the new process was decreased by 90 min.

ABSTRACT:The paper investigated the heavy metal ions adsorption by bio-adsorbent obtained from modifying bagasse pith. The bagasse pith, a main solid bio-waste from sugar and pulp industry, was treated by epichlorohydrin and diethylenetriamine. The pith before and after modification were analyzed to characterize its structure change by Fourier Transform Infrared Spectroscopy and Scanning Electron Microscope. It shown that numbers of minor fragments cohere to the surface of fibrous bundle of modified pith. The carboxyl groups has been introduced with the change of substitutional groups in aromatic skeletal of lignin on surface of pith. The kinetics and thermo-dynamic properties were studied. The results shown the adsorption process are well described by Langmuir isotherm and pseudo-2nd order model. It is considered that the bagasse pith, a renewable bio-waste, would be modified to treat the waste water polluted by heavy metal in further studies.
