My
book "Fundamentals of the theory of flotation" is one of the few
completely new theoretical books on flotation enrichment of minerals in the
world. In the book is reviewed and analyzed the main processes occurring in the
flotation system. My book presents all kinds of mineral flotation detail. Any
other book about the flotation in the world doesn’t have this.
I
tried to bring all of my industrial, university and scientific expertise in
this book of the fairly compact volume (192 pages).
The
book has a scientific novelty, and contains only the author's text and
illustrations. In the book "Fundamentals of the theory of flotation"
I present an affordable and popular form the quite complex theoretical issues,
unlike many books of other authors on the subject, often overwrought by
formulas and abstruse wording.
My
book is intended for a broad category of scientists, specialists, professors
and students.
