HYBRIDIZIED TECHNOLOGIES FOR THE TREATMENT OF MINING EFFLUENTS The main goal of this book is to review the principles, development, and performances of hybridized technologies that have been used for the treatment of mine effluents. Recent developments consist of the integration/hybridization of technologies to achieve the effective removal of pollutants from acid mine drainage (AMD) effluents in a stepwise manner such as to ensure that the cost of the process is minimized, and the resulting water is fit for purpose. This book presents eight specialized chapters that provide a state-of-the-art review of the different hybridized technologies that have been developed over the years for the treatment of mine effluent, including AMD. The successful implementation and challenges of these technologies are highlighted to give the reader a perspective on the management of such waste in the mining industry. In this innovative book, readers will be introduced to The limitations of passive and active treatment processes as stand-alone technologies while appraising the functioning and performances of these technologies when combined to address their challenges; The numerous approaches that have been considered over the years for effective combination of these technologies are explored taking into account their successful implementation at large scale as well as the long-term sustainability. Audience This book will be of interest to academic researchers from the fields of environment, chemistry, engineering, mineral processing, hydrometallurgy, geochemistry, and professionals including mining plant operators, environmental managers in the industries, water treatment plants managers and operators, water authorities, government regulatory bodies officers and environmentalists.

This book allows readers to grasp both the fundamentals and the latest technological advances in the field of mine drainage, which is increasingly crucial both environmentally and economically. Its extensive coverage of current and promising passive treatment technologies, combined with numerous practical guides, makes it an indispensable tool for early researchers seeking promising trends and identifying gaps. The book systematically explores recent literature on passive treatment research, classifying them as preventative, in-situ, and ex-situ solutions. It covers relevant passive treatments such as permeable reactive barriers, constructed wetlands, gravel bed reactors, saturated rock fills, and passivation techniques, among other common source control tactics. Each technology is discussed in terms of principal mechanisms, state-of-the-art technological advances, advantages and disadvantages, and suitability for a given mine drainage chemistry and flow regime. The book provides a comprehensive view of the entire field, offering researchers and policymakers a reference guide, research ideas, understanding, and practical applications for each technology. Furthermore, the contains an overview of recent trends in material selection for passive treatment applications, primarily through the use of industrial waste and by-products, which incorporate more sustainable practices in mine drainage remediation. Uniquely, the manuscript includes a flowchart based on water chemistry and flow rates to guide readers to ideal treatment options, along with written analysis to further support the readers’ decision-making. Overall, this equips early researchers in the field with knowledge of fundamentals and promising research routes when dealing with different mine drainage complexities while also providing them with promising research avenues that can advance the field further.

Acid Mine Drainage (AMD) is a serious environmental problem and the focus of a great deal of research. Passive treatment systems associated with wetlands and Anoxic Limestone Drains (ALDs) provide a low-cost, low-maintenance treatment in contrast to continuous chemical metering. The ALD adds alkalinity to the water allowing for a more rapid formation of iron precipitates. The abiotic oxidation ponds associated with these systems are expected to precipitate about 10-20 g/sq m-day of iron. The focus of this research is to evaluate two different ALD passive treatment systems in order to find ways to improve the efficiency of the abiotic oxidation of ferrous, thereby reducing the amount of land area required to treat the discharge. The two systems evaluated differed in that one system is a channel system, while the other is a series of ponds. The channel system has a large excess of alkalinity while the pond system has net mineral acidity. The study of the systems was conducted over a one-year period starting in January 1998 and ended in January 1999. The evaluation of each system included monitoring the chemistry and using MINTEQA2, a chemical equilibrium computer program to assist in the analysis. Of all the major cations in solution, ferrous is the only one that is removed in the system.

The Williams Brothers Mine is located in Mariposa County, California. Surface waters from the site drain into the south fork of the Merced River and the San Joaquin River Basin. The mine was developed in the 1980s and mined intermittently until 1996. In 1998, concerns of acidic drainage at the site arose. Effluent sampling by Engineering Remediation Resources Group (ERRG) found acid mine drainage (AMD) characterized by a pH of 3.9, sulphate concentrations of 100 mg/L and low metal concentrations of 0.074, 4.60, 1.23, 0.047 and 0.133 mg/L for Cu, Fe, Mn, Ni and Zn, respectively. The aim of this research was to evaluate passive treatment system alternatives for the mitigation of the AMD to meet water quality objectives for the San Joaquin River Basin. A bench-scale study was undertaken which consisted of 3 systems treating synthetic AMD: (1) a peat biofilter to remove dissolved metals followed by an anoxic limestone drain (ALD) to increase alkalinity and pH; (2) a sulfate reducing bacteria (SRB) bioreactor followed by an ALD, in which SRB reduce sulphate to sulfides, generating alkalinity and decreasing metal concentrations via metal sulfide precipitation; and (3) a SRB bioreactor. Synthetic AMD was produced to represent AMD characteristics observed at the site. The peat-ALD system effluent pH was 6.9 and concentrations of Fe and Cu decreased to below water quality objectives with concentrations of 0.008 and 0.06, respectively. The SRB-ALD and SRB system effluents met water quality objectives for pH and Cu, Ni and Zn metal concentrations. The effluent pH for both systems was 6.5. The SRB-ALD system reduced Cu, Ni and Zn to concentrations of 0.004, 0.016 and 0.025 mg/L, respectively. The SRB system reduced metal concentrations for Cu, Ni and Zn 0.006, 0.010 and 0.027 mg/L, respectively. Based on the bench-scale study, the pilot-scale system consisted of a combined passive treatment system containing a peat biofilter, SRB bioreactor and a limestone drain. Pilot-scale testing commenced on May 23rd, 2007. To date, some metal attenuation has been observed, with average effluent concentrations of Cu, Fe, Mn, Ni and Zn equal to

The report develops an approach for reliably evaluating the impact of proposed water pollution abatement plans for a river basin. A water quality simulation model is developed which has the capability of routing acid mine drainage through a river basin. A computer procedure providing for the optimization of alternatives is also developed. The simulation model is used to evaluate alternatives within a larger framework that involves optimization. The approach is to use the simulation as a method of impact assessment which is manipulated by optimization logic. Thus the simulation can be used in two ways: as a stand alone model or as an adjunct to optimization. The Tioga River Basin in Pennsylvania has been chosen as a case study. (Author Modified Abstract).
