This book provides a comprehensive review of the production of smelter grade alumina from bauxite ores. It emphasizes the best practices applied in the industry today but seen in a historical context with a view to future challenges and developments. The control of alumina quality is discussed in detail including the effects that alumina quality have on the aluminum smelter process with respect to environmental performance, current efficiency, and metal purity. The discussion of alumina quality will be relevant to people on the smelter side, as this is the interface between refinery and smelter. Emphasis is placed on the major steps of the Bayer Process including: digestion, clarification, precipitation, calcination, and management of water, energy, and bauxite residue. This book is a valuable resource for active, seasoned practitioners and for new engineers entering the industry.

The Light Metals symposia are a key part of the TMS Annual Meeting & Exhibition, presenting the most recent developments, discoveries, and practices in primary aluminum science and technology. Publishing the proceedings from these important symposia, the Light Metals volume has become the definitive reference in the field of aluminum production and related light metal technologies. The 2014 collection includes papers from the following symposia: •Alumina and Bauxite •Aluminum Alloys: Fabrication, Characterization and Applications •Aluminum Processing •Aluminum Reduction Technology •Cast Shop for Aluminum Production •Electrode Technology for Aluminum Production •Light-metal Matrix (Nano)-composites

Energy and sustainability are critical factors for economic development, and this comprehensive reference provides a detailed overview and fundamental analysis of sustainability issues associated with the aluminum industry. This publication brings together articles on the concepts and application of life-cycle assessments that benchmark aluminum-industry efforts towards sustainable development. Chapters provide energy-use data for primary and secondary aluminum production and processing along with future energy saving opportunities in aluminum processing. Life-cycle assessments provide basic, factual, information on the modeling of material flow in the industry, its products, and most importantly energy savings involved with recycling. Coverage includes various scrap sorting technologies and the positive impact of lightweight aluminum in transportation and infrastructure.

The Light Metals series is widely recognized as the definitive source of information on new developments in aluminum production technology. This new volume presents proceedings from 2013's Light Metal Symposia, covering the latest research and technologies on such areas as alumina and bauxite, aluminum reduction technology, electrode technology for aluminum production, cast shop for aluminum production, aluminum processing aluminum alloys, and cost affordable titanium IV. It also includes papers from a keynote presentation session discussing impurities in the aluminum supply chain are also included.

This book explores sustainable mining knowledge, assessing researchers on the impacts of waste and new approaches to negotiating these impacts. Mining has always been a profitable venture; however, it comes with several boons and banes. The significant advantages of mining include employment generation, the establishment of townships and trade centers, and socio-economic growth. However, the mining activity is a significant cause of environmental degradation, including soils, atmosphere, water, solid wastes, changed topography, and health hazards. This book emphasizes value-added products from mining wastes and innovations for balancing environment, ecology, and economy. This book is designed for miners, policymakers, professionals, researchers, scientists, industrialists, and environmental agencies.
