Download or read book Metal Removal and Recovery from Mining Wastewater and E waste Leachate written by Suthee Janyasuthiwong and published by CRC Press. This book was released on 2020-02-18 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metal contamination in the environment is a persisting global issue. The metal reservoirs in the earth have declined due to society’s needs and due to uncontrolled mining activities. Therefore, the idea to recover metals from waste streams has emerged. In this thesis, cost competitive technologies such as adsorption using agro-wastes and precipitation using an inverse fluidized bed (IFB) reactor were investigated, with special emphasis on the recovery of base metals. Groundnut shell showed good potential for metal (Cu, Pb and Zn) removal. From artificial neural network modeling, the performance of the sulfate reducing bacteria (SRB) was found to be strongly pH dependent; the removal efficiency of Cu and Zn in the IFB at pH 5.0 was >97%. Electronic waste is a good candidate as secondary metal resource. The recovery of Cu from computer printed circuited boards (PCBs) using biogenic sulfide precipitation was investigated as well. Using this technology, Cu could be recovered at ~0.48 g Cu/g PCBs.

Download or read book Sustainable Heavy Metal Remediation written by Eldon R. Rene and published by Springer. This book was released on 2017-10-13 with total page 288 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents an assortment of case-studies pertaining to the use of sustainable technologies for heavy metal removal and recovery from mining and metallurgical wastes, construction and demolition wastes, spent catalysts and electronic wastes. Wastewaters from diverse industrial and mining activities have caused pollution problems, but these sectors also serve as a hotspot for metal recovery. Several metal removal technologies based on physical, chemical and biological processes have been successfully implemented in full-scale operation, while metal recovery, which is beneficial for economic and environmental reasons, is still limited due to challenges arising from downstream processing. For instance, microbial recovery (bioleaching) of metals from their ores is an established technology with a number of full-scale applications. Bioleaching of electronic wastes to recover metals is also a highly promising technology with low environmental impact and high cost-effectiveness; yet, this technology is still at its infancy. As the individual chapters of this book focuses on the applications and limitations of different technologies, this book will serve as an excellent resource for chemical engineers, environmental engineers, mining engineers, biotechnologists, graduate students and researchers in these areas.

Download or read book Waste as a Resource written by R E Hester and published by Royal Society of Chemistry. This book was released on 2013-07-01 with total page 253 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume of waste produced by human activity continues to grow, but steps are being taken to mitigate this problem by viewing waste as a resource. Recovering a proportion of waste for re-use immediately reduces the volume of landfill. Furthermore, the scarcity of some elements (such as phosphorous and the rare-earth metals) increases the need for their recovery from waste streams. This volume of Issues in Environmental Science and Technology examines the potential resource available from several waste streams, both domestic and industrial. Opportunities for exploiting waste are discussed, along with their environmental and economic considerations. Landfill remains an unavoidable solution in some circumstances, and the current situation regarding this is also presented. Other chapters focus on mine waste, the recovery of fertilisers, and the growing potential for compost. In keeping with the Issues series, this volume is written with a broad audience in mind. University students and active researches in the field will appreciate the latest research and discussion, while policy makers and members of NGOs will benefit from the wealth of information presented.

Download or read book Recovery and Recycling of Valuable Metals written by Dariush Azizi and published by Mdpi AG. This book was released on 2022-01-27 with total page 258 pages. Available in PDF, EPUB and Kindle. Book excerpt: Metals have always played a significant role in human life, and the current global growth and prosperity are directly dependent on these materials. With the rapidly growing global demand for metals, their extraction from natural minerals (as their primary sources) has been enhanced, causing a significant reduction in the grade and quality of the ores in ore deposits and leading to the production of huge amounts of waste, which requires management. In light of this, new proposals to develop more advanced metal recovery technologies from minerals are needed. Additionally, the huge quantity of waste generated through all steps of metal production is known to be a source of environmental pollution, while its valorization can create value via recycling metals or even though use in the production of other valuable materials. Such waste valorization is also in line with the United Nations' Sustainable Development Goals (SDGs), as well as the implementation of the Paris Agreement. In this regard, the recycling of end-user products in order to reproduce valuable metals can also create significant value and reduce mining activities, and thus, their harmful consequences worldwide. Therefore, research and development in the state-of-the-art technologies for the recovery and recycling of metals are absolutely necessary. The aim of this Special Issue was to collect a range of articles on different aspects of valuable metal recovery and recycling from primary and secondary sources, as well as to decipher all new methods, processes, and knowledge in valuable metal production. We hope that this open access Special Issue will provide a great opportunity to demonstrate the work of researchers working in this area all around the world and help to provide new ideas for researchers who are working in the areas of hydrometallurgy, mineral processing, and waste recycling and valorization.
Download or read book Treatment and Recovery of Heavy Metals from Acid Mine Drainage Using Polymer Chelation and Membrane Filtration written by and published by . This book was released on 1993 with total page 15 pages. Available in PDF, EPUB and Kindle. Book excerpt: The process considered in this study is based on the use of sequestering or chelating agents, with emphasis on water-based macromolecular compounds, which demonstrate selectivity for the extraction of copper, lead, zinc, and cadmium, coupled with an appropriate membrane that would effectively separate the organic metal complex and allow the metal-free aqueous phase to permeate through the membrane as a treated effluent. The process design has the objectives of generating a concentrate which would contain close to 100 percent of the metal chelates in the solution which could then be acidified in order to recover the metals from the chelants, allowing both the metals and the chelants to be reused. The method of the polymer binding-membrane filtration was evaluated for the removal of heavy metals from acid mine drainage. The experimental studies were done on bench-scale level using both actual and synthetic mining effluents. The report includes test results, discussion, and recommendations for future work.

Download or read book Management and Mitigation of Acid Mine Drainage in South Africa written by Mujuru, Munyaradzi and published by Africa Institute of South Africa. This book was released on 2017-02-03 with total page 359 pages. Available in PDF, EPUB and Kindle. Book excerpt: South Africa is facing the increasing challenge of acid mine drainage (AMD) whose genesis is the country’s mining history, which paid limited attention to post-mining mine site management. In mineral resource-rich Africa, this has emerged as one of the most daunting challenges of our time. South Africa has been bold in its approach to mitigating this problem, although the challenge is multi-faceted. On a positive note, substantial research has been conducted to confront the challenge. However, thus far, the research has been largely fragmented. This book builds on the work that has been done, but also provides a refreshing multi-disciplinary approach that is useful in addressing the AMD challenges that South Africa and the continent face. Whilst addressing the problem as a scientific and engineering challenge, the book also exposes the economic, policy and legal challenges involved in addressing the problem. The book concludes, quite uniquely, that AMD is an opportunity that can be used by South Africa and Africa to solve problems, such as acute water shortage, as well as mineral recovery operations.
