The book "Experience in the use of pneumatic flotation machines for coal flotation" by Vladimir Ilyich Klassen is a unique study that immerses the reader in the world of coal enrichment technologies. In modern production, where efficiency and environmental friendliness are becoming key factors, this publication represents an important contribution to the understanding of coal flotation processes and the use of pneumatic machines in this area. Klassen, with extensive experience in mining and mineral processing, shares his knowledge and practical experience, which can be of interest to both specialists and students studying mining and processing technologies. The book will be useful to engineers, technologists and researchers, as well as anyone interested in modern methods of coal enrichment and their application in real conditions. In his work, the author considers various aspects of the operation of pneumatic-type flotation machines, ranging from their design and principle of operation to practical examples of application in various conditions. Klassen not only describes the theory, but also shares real cases, which makes the material particularly valuable for practitioners. The reader will be able to learn how to choose the right equipment for specific conditions, what factors affect the efficiency of flotation and how to minimize the cost of coal processing. The topics raised in the book cover not only technical aspects, but also economic and environmental issues related to coal enrichment. In the face of global climate change and growing environmental demands, issues of sustainable production and minimizing the impact on the environment are becoming especially urgent. Klassen focuses on how modern technology can help solve these problems, and offers readers new approaches to process optimization. The author's style is distinguished by clarity and accessibility, which makes complex technical concepts understandable even for those who are just beginning to get acquainted with this topic. Klassen skillfully combines a scientific approach with practical recommendations, which allows the reader not only to understand the theory, but also to apply it in practice. His previous works, such as “Coal Enrichment Technology” and “Modern Methods of Mineral Processing”, have also gained recognition in professional circles and serve as the basis for further research. This book will be an excellent addition to the library of everyone interested in the mining industry, as well as for students and teachers studying relevant disciplines. It will help expand the horizons of knowledge and deepen understanding of the processes taking place in the world of the coal industry. If you are looking for information on modern coal-enrichment technologies, want to learn about the use of pneumatic flotation machines or just interested in the mining industry , "Experience in the use of pneumatic-type flotation machines for coal flotation" by Vladimir Ilyich Klassen is a book which you should not miss. Immerse yourself in the world of innovative technologies and discover new horizons in the field of coal flotation!
