The book "Control of metal content in ore pulps and solutions by the method of electronic paramagnetic resonance" by P. Solenkina is a unique and in-depth study that immerses the reader in the world of modern methods of analysis and control in the mining industry. This publication will be of particular interest to specialists in the field of metallurgy, mining, as well as students and graduate students studying relevant disciplines. In his book, Solenkin describes in detail the method of electronic paramagnetic resonance (EPR), which to date has become one of the most effective tools for controlling the content of metals in ore pulps and solutions. The author focuses on how this method allows not only to accurately determine the concentration of various metals, but also to identify their chemical state, which is a key aspect for optimizing mineral processing processes. Readers interested in the mining industry, ecology, as well as those working in the field of analysis and quality control, will find in the book a lot of useful information. Soluzhenkin shares his experience and knowledge, which makes the material accessible and understandable even for those who are just starting their way in this field. The book will be useful to both practitioners and researchers seeking to deepen their knowledge of modern methods of analysis. The topics raised in the book cover a wide range of issues related to environmental safety, resource processing efficiency, and new technologies in the mining industry. Soluzhenkin emphasizes the importance of metal content control not only in terms of economic benefits, but also in the context of sustainable development and environmental protection. In the face of global climate change and growing environmental demands, such studies are becoming especially relevant. The author's style is distinguished by clarity and logical presentation, which makes it easy to assimilate complex scientific concepts. Sollenkin uses many examples from practice, which makes the material more lively and visual. His previous work is also noteworthy, as they demonstrate a deep understanding of the subject and a commitment to introducing innovative solutions into traditional processes. The book "Control of metal content in ore pulps and solutions by electronic paramagnetic resonance" will become a reference for anyone who wants to be aware of the latest achievements in the field of metallurgy and mining. It not only enriches knowledge, but also inspires new research and development. If you are looking for information about modern methods of analysis, ecology in the mining industry or want to understand how technology can change the approach to resources, this publication should definitely take place on your shelf. Thus, this work is not just a book, but a whole source of knowledge that will help you better understand the complex processes taking place in the mining industry, and open up new horizons for your professional growth. Do not miss the opportunity to get acquainted with the work of Solenkin - it will become your reliable assistant in the world of science and technology
