Handbook of Flotation Reagents: Chemistry, Theory and Practice:
Flotation of Gold, PGM and Oxide Minerals, Volume 2 focuses on the
theory, practice, and chemistry of flotation of gold, platinum
group minerals (PGMs), and the major oxide minerals, along with
rare earths. It examines separation methods whose effectiveness is
limited when using conventional treatment processes and considers
commercial plant practices for most oxide minerals, such as
pyrochlore-containing ores, copper cobalt ores, zinc ores, tin
ores, and tantalum/niobium ores. It discusses the geology and
mineralogy of gold, PGMs, and oxide minerals, as well as reagent
and flotation practices in beneficiation. The book also looks at
the factors affecting the floatability of gold minerals and
describes PGM-dominated deposits such as Morensky-type deposits,
hydrothermal deposits, and placer deposits. In addition, case
studies of flotation and beneficiation in countries such as Canada,
Africa, Russia, Chile, and Saudi Arabia are presented. This book
will be useful to researchers, university students, and professors,
as well as mineral processors faced with the problem of
beneficiation of difficult-to-treat ores.
The book is focused primarily on characteristics and determinative
methods of reservoir orientation, the concept of vector well

Weather Analysis and Forecasting: Applying Satellite Water Vapor
Imagery and Potential Vorticity Analysis, Second Edition, is a
step-by-step essential training manual for forecasters in
meteorological services worldwide, and a valuable text for graduate
students in atmospheric physics and satellite meteorology. In this
practical guide, P. Santurette, C.G. Georgiev, and K. Maynard show
how to interpret water vapor patterns in terms of dynamical
processes in the atmosphere and their relation to diagnostics
available from numerical weather prediction models. In particular,
they concentrate on the close relationship between satellite
imagery and the potential vorticity fields in the upper troposphere
and lower stratosphere. These applications are illustrated with
color images based on real meteorological situations over
mid-latitudes, subtropical and tropical areas.

Ground water resources are receiving global attention, as human
population growth and development cause significant changes to the
earth system. It plays a major role in ensuring livelihood security
in many parts of South Asia and its contribution to poverty
alleviation is substantial. The complex nature of ground water
problems in the Indian Sub-continent requires a precise delineation
of the ground water regimes in different hydro geological settings
and socio-economic conditions and is a primary necessity for
sustainable and equitable management. Strategies to respond to
ground water over-exploitation and deteriorating water quality must
be based on a new approach. Practical policies and various solution
options urgently need to be formulated and implemented to prevent
the development problems. There is pressing need to evolve workable
methods and approaches based on modern scientific researches on
ground water resources, as well as to build a social framework
including community participation at all levels for a ground water
development system. The community participation in water pumping
policies, incentives of efficient use, affordability of low income
users and other vulnerable groups, water awareness are prime
factors for success of any ground water based water supply project.
This book focuses on scientific and technological aspects of
groundwater-resources assessment and surveillance. It describes
relevant risks and investigates selected techniques for the
monitoring and mitigation of the individuated threats to
groundwater quality. The authors discuss the concepts of
groundwater-resources protection and offer examples of both
geogenic and anthropogenic degradation of groundwater quality, such
as heavy metals from mining activities and natural water-rock
interactions, as well as risk of contamination due to geological
CO2 storage practices etc. The volume also covers non-invasive
monitoring techniques and briefly addresses innovative sensor
technologies for the online assessment of water quality.
Furthermore, the role played by geochemical techniques, the
potential of environmental isotopes and the support provided by
physical modelling are highlighted. The chapters guide the reader
through various viewpoints, according to the diverse disciplines
involved, without aiming to be exhaustive, but instead picking
representative topics for their relevance in the context of
groundwater protection and control. This book will be of interest
to advanced students, researchers, policy-makers and stakeholders
at various levels.

An illustrated guide to introduction to major fossil groups.
Research into the anthropogenic and taphonomic processes that
affect the formation of maritime archaeological resources has grown
significantly over the last decade in both theory and the analysis
of specific sites and associated material culture. The addition of
interdisciplinary inquiry, investigative techniques, and analytical
modeling, from fields such as engineering, oceanography, and marine
biology have increased our ability to trace the unique pathways
through which archaeological sites progress from initial deposition
to the present, yet can also link individual sites into an
integrated socio-environmental maritime landscape. This edited
volume presents a global perspective of current research in
maritime archaeological landscape formation processes. In addition
to "classically" considered submerged material culture and
geography, or those that can be accessed by traditional underwater
methodology, case studies include less-often considered sites and
landscapes. These landscapes, for example, require archaeologists
to use geophysical marine survey equipment to characterize
extensive areas of the seafloor or go above the surface to access
maritime archaeological resources that have received less scholarly
attention.
This book covers the more basic aspects of carbonate minerals and
their interaction with aqueous solutions; modern marine carbonate
formation and sediments; carbonate diagenesis (early marine,
meteoric and burial); the global cycle of carbon and human
intervention; and the role of sedimentary carbonates as indicators
of stability and changes in the Earth's surface environment. The
selected subjects are presented with sufficient background
information to enable the non-specialist to understand the basic
chemistry involved. Tested on classes taught by the authors, and
approved by the students, this comprehensive volume will prove
itself to be a valuable reference source to students, researchers
and professionals in the fields of oceanography, geochemistry,
petrology, environmental science and petroleum geology.
This book presents the first overview of the composition and
structure of the Earth's lower mantle. The first part focuses on
the study of lower-mantle minerals, identified as inclusions in
diamonds from different regions of the world. Three associations
are established among the lower-mantle minerals: ultramafic, mafic,
and carbonatic. The carbonatic association is of particular
interest because it characterizes the media of natural diamond
formation. In turn, the second part analyzes the structure of the
lower mantle, revealing its heterogeneous composition. It is based
on the results of experiments demonstrating phase transitions in
lower-mantle minerals, and on seismological data. Deep-seated
earthquakes point to the presence within the lower mantle of
numerous seismic boundaries caused by mineral structure
transitions. In closing, the last part of the book compares
observed data with experimental data, highlighting several
discrepancies that indicate Earth may have a more complex planetary
history than previously assumed, and examining its primarily
non-chondritic composition.
This book helps to establish a simple framework to identify and use
bird species as a bioindicator for high nature value (HNV)
farmlands. This book focuses on suitable methods for monitoring the
HNV areas, and presents the results of several case studies. The
chapters put forward ways to integrate ecosystems assessment,
geographical information systems (GIS) and strategies for
conservation of local biodiversity. An innovative framework focuses
on the use of species distribution models (SDMs) in order to
explore the importance of each characteristic of HNV farmlands.
Furthermore, the book examines the relationships among bird species
richness, land use diversity and landscape metrics at a local scale
in the farmlands.
