Zinc is a common contaminant in wastewater electroplating, metal finishing, and many other industrial processes. This paper presents the results of work which is intended to be the first step in an evaluation of the use of concentrated and pelletized magnetite for the adsorption of metals from industrial wastewater. The magnetite used is a cold carbon bonded material which is formulated for the steel industry as a complete product ready for feed to the furnaces. The specific objective of this work was to determine the zinc adsorption capacity of the prepared magnetite pellets through batch tests that were designed to allow the development of an adsorption isotherm. Future work would explore the potential for use of the spent adsorbent in the steel making process, thereby allowing the recovered metals to be recycled into steel products, while avoiding spent adsorbent disposal costs. Although not evaluated in this study, an additional advantage of the use of magnetite as an adsorbent is that it can be magnetically separated from the wastewater.
