Basics of Metal Mining Influenced Water is a must-read for planners, regulators, consultants, land managers, students, researchers, or others concerned about the environmentally sound management of metal mine wastes and drainage quality.

The first of a series of six handbooks on technologies for managing metal mine and metallurgical process draining, this book offers a unique, comprehensive perspective on the subject. Unlike other texts that focus primarily on acid drainage from coal mines, the authors examine both acidic and neutral pH waters that can be hazardous to the environment.

Planning a new mine in today’s increasingly contentious regulatory and political environment demands a different philosophy. Basics of Metal Mining Influenced Water takes an innovative, holistic approach by considering all aspects of the mine life cycle, including closure.

Written by a team of experts from state and federal governments, academia, and the mining industry, Basics of Metal Mining Influenced Water also discusses the major physical and chemical relationships between mining, climate, environment, and mine waste drainage quality.

The authors have included an extensive glossary defining hundreds of technical terms for easier reading and understanding.

Beneficiation of Phosphate Ore examines various methods for processing phosphate rock, an important mineral commodity used in the production of phosphoric acid. The majority of phosphoric acid is produced by the wet process, in which phosphate rock is reacted with sulfuric acid to produce phosphoric acid and gypsum (calcium sulfate dihydrate). This wet process demands a phosphate rock feed that meets certain specifications to produce phosphoric acid efficiently and economically. Beneficiation of Phosphate Ore thoroughly explains the methods used in beneficiation of different types of phosphate ores for use in the wet process. The mineralogical properties of the two major types of phosphate deposits, sedimentary and igneous, are described along with the processing methods. The benefits and disadvantages of each process are discussed in detail.

CONTENTS: 

• Sources of Phosphate Rock
• Beneficiation of Siliceous Sedimentary Phosphate Ores
• Beneficiation of High-MgO Sedimentary Phosphate Ores
• Beneficiation of Igneous Phosphate Ores

• Recovery of rare earths from phosphate
• Uranium recovery from phosphoric acid
• Recovery of magnesium from high-dolomite phosphate rock
• Phosphoric acid purification via byproducts production

• Environmental lawsuits have put a stop to one of the largest phosphate mines in the world.
• Other operations are closing because of the depletion of phosphate reserve.
• The increasing proportion of high organic and high dolomite ores has caused beneficiation costs to skyrocket.
• There is a growing urgency for the sustainable development and recycling of phsophate resources.
• Dozens of internationally respected experts provide insights on key breakthroughs that are on the drawing boards or being implemented today that will shape the industry in the years ahead.

This compilation from the 2018 Beneficiation of Phosphates Conference includes insights from dozens of internationally respected experts on key breakthroughs that will shape the industry in the years ahead. Learn from the best and the brightest in the industry.

The book reflects on the recent impetus for reviewed research in the recovery of rare earth elements from secondary resources. Recovery of rare earth elements from phosphate processing has been one of the important projects of the Critical Materials Institute (CMI). This compilation highlights some of the findings of the CMI phosphate project.

Learn how competition in the flotation reagent market has stimulated innovative reagent development work. As a result, new reagents have been formulated and targeted at dolomite flotation, calcite flotation, more selective phosphate flotation, and even flotation in seawater.

The Florida phosphate industry is seeing improvements in the processing of high dolomite reserves. Recent encouraging developments include new reagents that can float dolomite without using phosphoric acid as a phosphate depressant, reducing MgO content in the “Crago” flotation concentrate thus allowing blending of some high-dolomite pebbles in the final product, and innovative gravity separation.

Topics include:

• Sustainability and the Environment
• Comprehensive Extraction and Smart Chemistry
• Flotation Fundamentals and Reagents
• Advances in Processing Technology and Equipment

More than 100 internationally respected authors from 20 countries explore the latest developments in an industry experiencing unprecedented change and prosperity.

In Beneficiation of Phosphates you'll learn about promising new technologies such as enhanced flotation and breakthroughs in on-line analysis.

Flocculation-based deep cone thickening technology for fine waste tailings treatment is also examined. This has the potential to eliminate a host of environmental problems associated with waste disposal.

These and other compelling case histories provide insights into ensuring the long-term viability of an industry that "feeds" the world with this life-sustaining, yet nonrenewable resource.

Beneficiation of Phosphates: Technology Advance and Adoption is an authoritative, up-to-date resource for industry managers, engineers, regulators, and environmental groups, as well as mining and minerals processing students, faculty, and researchers.

Coal mining and preparation have had a long history in the United States and the world, serving as the engine of growth for many industries. Today, new sources of energy, increased environmental awareness and more stringent regulations from the U.S. Environmental Protection Agency and other organizations are changing the way coal is found, extracted and used. As a result, fine coal cleaning, dewatering and refuse disposal are now at a major crossroads.

The increased level of fines, and near-density material in the inferior seams being mined today, necessitates the development of more efficient fine coal cleaning devices. This in turn requires improvements in traditional dewatering techniques to address the need for acceptable moisture levels in plant products. Moreover, the larger volume of fine refuse being generated, coupled with harsher disposal regulations, require upgraded treatment options.

This book is a compilation of information presented at the 2012 Fine Coal Symposium, sponsored by the Coal Preparation Society of America, the Pittsburgh Section of the Society of Mining, Metallurgy & Exploration Inc. and the Pittsburgh Coal Mining Institute of America. Provided by international coal companies, major research organizations, technology developers and industry leaders, the information includes both general knowledge and in-depth discussion on the current challenges facing the industry, techniques for designing more efficient plants and new cleaning and dewatering technologies.

The book is a practical yet cutting-edge resource for plant designers, engineers and other practitioners, and for university students and faculty.
