This book was released on 2017-10-01 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: The single most important factor for the successful application of a geochemical model is the knowledge and experience of the individual(s) conducting the modeling. Geochemical Modeling for Mine Site Characterization and Remediation is the fourth of six volumes in the Management Technologies for Metal Mining Influenced Water series about technologies for management of metal mine and metallurgical process drainage. This handbook describes the important components of hydrogeochemical modeling for mine environments, primarily those mines where sulfide minerals are present—metal mines and coal mines. It provides general guidelines on the strengths and limitations of geochemical modeling and an overview of its application to the hydrogeochemistry of both unmined mineralized sites and those contaminated from mineral extraction and mineral processing. The handbook includes an overview of the models behind the codes, explains vital geochemical computations, describes several modeling processes, provides a compilation of codes, and gives examples of their application, including both successes and failures. Hydrologic modeling is also included because mining contaminants most often migrate by surface water and groundwater transport, and contaminant concentrations are a function of water residence time as well as pathways. This is an indispensable resource for mine planners and engineers, environmental managers, land managers, consultants, researchers, government regulators, nongovernmental organizations, students, stakeholders, and anyone with an interest in mining influenced water. The other handbooks in the series are Basics of Metal Mining Influenced Water; Mitigation of Metal Mining Influenced Water; Mine Pit Lakes: Characteristics, Predictive Modeling, and Sustainability; Techniques for Predicting Metal Mining Influenced Water; and Sampling and Monitoring for the Mine Life Cycle.

This book was released on 2012-12-06 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is not long ago that scientists realized, our study and understanding of most environmental problems call for a cross-sectional, more holistic view. In fact, environmental geochemistry became one of the legs to stand on for such a required interdisciplinary approach. Geochemists do not only describe the elemental composition and pro cesses of natural systems, such as soils, ground or surface waters, but they also establish the methodology to quantify material rates and turnover. Today, geochemical expertise has become indispensable when monitoring the fate of noxious chemicals, like-metallic pollu tants released to the environment. To know how trace metals will be have and react in complex systems under changing conditions, might provide us with a more realistic estimate of what is really acceptable in terms of quality standards. This would ease the formulation of ade quate environmental objectives, strategies and criteria to handle emerging pollution situations. Moreover, to take notice of geochemi cal principles will support our endeavor to improve the way we deal with limited and nonrenewable resources. It is exactly here, i. e. at the interface between natural elemental processes and the way we use them, that geochemical approaches meet the demand of technical at tempts to minimize the impact of environmentally relevant activities, like mining, waste handling, or manufacturing. The consideration to include geochemically derived concepts into the search for technical solutions is not really new, but has a long tradition during the evolution of modern societies.

Download or read book Geochemical Modeling of Groundwater Vadose and Geothermal Systems written by Jochen Bundschuh and published by CRC Press. This book was released on 2011-12-23 with total page 336 pages. Available in PDF, EPUB and Kindle. Book excerpt: Geochemical modeling is an important tool in environmental studies, and in the areas of subsurface and surface hydrology, pedology, water resources management, mining geology, geothermal resources, hydrocarbon geology, and related areas dealing with the exploration and extraction of natural resources. The book fills a gap in the literature through its discussion of geochemical modeling, which simulates the chemical and physical processes affecting the distribution of chemical species in liquid, gas, and solid phases. Geochemical modeling applies to a diversity of subsurface environments, from the vadose zone close to the Earth’s surface, down to deep-seated geothermal reservoirs. This book provides the fundamental thermodynamic concepts of liquid-gas-solid phase systems. It introduces the principal types of geochemical models, such as speciation, reaction-path or forward, inverse- and reactive-transport models, together with examples of the most common codes and the best-practices for constructing geochemical models. The physical laws describing homogeneous and heterogeneous chemical reactions, their kinetics, and the transport of reactive solutes are presented. The partial differential or algebraic equations representing these laws, and the principal numerical methods that allow approximate solutions of these equations that can provide useful solutions to model different geochemical processes, are discussed in detail. Case studies applying geochemical models in different scientific areas and environmental settings, conclude the book. The book is addressed to students, teachers, other professionals, and to the institutions involved in water, geothermal and hydrocarbon resources, mining, and environmental management. The book should prove useful to undergraduate and graduate students, postgraduates, professional geologists and geophysicists, engineers, environmental scientists, soil scientists, hydrochemists, and others interested in water and geochemistry.

This book was released on 2020-10-06 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book discusses potential mineral belts in various geotectonic regions around the globe, with a particular focus on concealed deposits, in order to highlight new areas for geochemical exploration and modelling. In recent years, the application of statistical methods using qualitative and, wherever possible, quantitative earth science data has become increasingly common for the evaluation of both offshore and terrestrial mineral resources. The book examines these approaches and provides examples from India, which are also applicable to deposits around the world, particularly those in South and South East Asia. The main objective of geochemical exploration and modelling is to present the geometry of the deposit in three dimensions. As such, the book describes the various conventional and non-conventional techniques of exploration geochemistry, especially in the context of concealed terrestrial and offshore mineral deposits. It serves as a guide for field geologists, geochemists, students, research scholars and scientists interested in earth science for the exploration of concealed mineral deposits and evaluation of their resources.
