The prose poems of Helen Alderfer showcased in The Mill Grinds Fine are vignettes from her life as one of the earliest Mennonite women writers. She shows us the inside story of earlier times, tells the tales of a modern maturity, celebrates the natural world, and exalts the quest for the eternal. Alderfers poetry should appeal to general readers, especially those drawn to accessible, down-to-earth, yet still lyrical descriptions of ordinary life as well as lifes larger stages and transitions.

An in-depth examination of the oldest engineering process, The History of Grinding begins at the start of agriculture and outlines how size reduction developed over the centuries(without completely immersing the reader in technical detail). Great technical achievements have led to the machines of today, which can grind solid particles at the rate of tens of thousands of tons per day. One certainty is the existence of the continuing need for size reduction to develop and fit the lifestyles of people both today and in the future. Photos and illustrations gleaned from numerous sources, a glossary, reference list, and index enhance the text. Chapters include Size Reduction from the Stone Age to the Space Age; The Science and the Scientists; Hand Stones; Water Wheels, Windmills, and Beyond; Stamp Mills and Crushers; Roller Mills; Tumbling Mills; Fine-Grinding Mills; Classifiers; Explosive Rock Breakage; and Size Reduction in the 21st Century.

This textbook is written primarily for undergraduate and postgraduate students of metallurgical and materials engineering to provide them with an insight into the emerging technology of powder metallurgy as an alternative route to conventional metal processing. It will also be useful to students of materials science, mechanical engineering and production engineering to understand and appreciate the importance of powder metallurgy as an effective and profitable material processing route to produce a variety of products for engineering industries. The book will enable the students as well as practising engineers to understand and practise the science and technology of powder production and processing, as well as to choose the right method to suit the application in hand. The various techniques used for powder production and the versatile nature of these techniques to produce a wide range of powders have been highlighted with suitable examples. Characterization of powders and subsequent compaction methods have been discussed with due reference to the final application. Novel consolidation techniques for advanced applications have been dealt with. Sintering of the compacts and the mechanisms involved in sintering have been discussed in detail. The book covers most of the recent developments in powder metallurgy such as atomization, mechanical alloying, self-propagating high-temperature synthesis, metal injection moulding and hot isostatic pressing. Questions and problems have been given at the end of each chapter. A glossary of relevant terms in powder metallurgy has also been included for ready reference.

Run-of-mine ore processing is a method of added value in which undesirable gangue-bearing minerals are discarded to obtain the desired minerals. Mineral processing has tangible benefits including savings in freight and handling, and the recovery of metal values from the slag as well as intangible benefits such as mineral conservation, environment protection by filling the mine using gangue-bearing minerals, and energy saving. This book provides rudimental, theoretical and operational knowledge of mineral processing along with coal characterisation and processing of ores of metallic and industrial minerals. It also explains definitions and techniques, along with basic formulas and practical examples. This book is designed for professionals in geology, mining, mineral, metallurgical and chemical engineering. The eccentric feature of this book is the introduction of simple numerical calculations for evaluation of the processes which in turn help understand the concepts with enhanced clarity and handle day-to-day operations of mineral processing plants. Therefore, it can be used both as a simple reference guide and a concise course in mineral processing.
