Sustainable Gold Mining Wastewater Treatment by Sorption Using Low-Cost Materials: UNESCO-IHE PhD Thesis

by Mike Agbesi Acheampong

Overview

Sorption technique was employed to remove heavy metals from gold mining effluent using natural and plant materials for sustainability. An assessment of the effluent quality of a gold mining company in Ghana indicated that arsenic, copper and cyanide were the major pollutants in the process effluent. Arsenic and copper were successfully removed from the effluent by the studied materials. The research showed that the down-flow fixed-bed treatment configuration is an ideal system for the simultaneous removal of copper and arsenic from low concentration gold mining effluent, in addition to other heavy metals present in very low concentrations.

Editorial Reviews

"The authors of this book set out to achieve the goal of presenting electromagnetics for electrical machines in a simple and systematic manner. I think they achieve that goal. They reduce Maxwell’s equations to Laplace’s equation, Poisson’s equation, wave equation, and eddy current equation and apply them to electrical machines."
—Matthew Sadiku, Prairie View A&M University

"I particularly value the approach taken of developing accurate theoretical electromagnetic models for several electrical machine structures. Traditional approaches of using lumped element models for machine parts, and then trying to modify the resulting equivalent network by taking into account the effect of these elements having non-zero physical size in a piece-meal fashion do not develop the user’s basic comprehensive insight into all aspects of the electromagnetic fields which can have some effect on machine behavior."
—Philip H. Alexander, Electrical and Computer Engineering, University of Windsor
