The purpose of this book is to provide a broad, comprehensive,
up-to-date coverage of current beneficiation techniques and
processes that are used for both metallic and nonmetallic minerals;
and for other materials, such as household and industrial solid
wastes, that are also processed by conventional beneficiation
methods in their standard methods of recycling and reclamation.
Conservation of natural resources is an adjunct of beneficiation in
that we have used up once-available deposits of high-grade ores,
leaving only the low-grade deposits that must be beneficiated to
upgrade them to sufficiently high levels for processing and metal
recovery by current extractive technology. Conservation is also
important in the reclamation and recycling of indestructible,
noncorrosive materials, so that they may be recovered and reused
many times over. The mainly physical, relatively uncomplicated,
beneficiation treatments also save large quantities of energy, as
these comparatively simple operations are all relatively low energy
consumers, when compared with the later separation operations of
pyro and electrical nature, which are very high energy consumers.
Environmentally, both air and water pollution from beneficiation
treatments are either quite low or can easily be controlled, and
are gas-free and operated at ambient temperature, to make them one
of the cleaner and lower polluting processes used in material
treatments.
