Phytoremediation: A novel approach for utilization of iron-ore wastes

Abstract

Large amounts of toxic contaminants are being released to the environment around the globe from rapid urbanization and industrialization. Among such contaminants are industrial wastes and ore tailings that result from worldwide mining activities. In mining operations, during the processing of low-grade ores, significant quantities of wastes or tailings are produced. The overburden material (also known as "waste"), generated during surface mining of minerals, causes serious environmental hazards if surrounding flora and fauna are not properly protected. It has been roughly estimated that for every ton of metal extracted from ores, roughly 2-12 ton of overburden materials are being removed. © 2010 Springer New York.
