Description
Environmentally, the past 10-15 years have experienced a very positive approach to improving the quality of effluents discharged from mining and milling processes, and ultimately the quality of seepage from the tailings impoundment area into the environment. This book assembles all the various aspects of the process and of tailings management which have an impact on the environment, thus providing significant examples to help those involved in tailings problems. The text is devoted to the many practical aspects of tailings management - the concerns, the problems, the solutions where knowledge exists, and the presentation of a methodology to examine mine and metallurgical wastes for the ultimate objective of designing the best disposal option for that particular site. Contents: 1. Mining - The Issues. Introduction. Tailings and waste rock analyses. Disposal. Reclamation. Water recycle. In-plant abatement. Toxicity of effluents. Ongoing research. Concerns of public and legislative bodies. Corporate responsibility. 2. Development of Waste Water Regulations and Guidelines. 3. Influence of the Mining and Mineral Extraction Process. Introduction. Mining.
