Echoing novels like Karen Russell's Swamplandia! and Carol Rifka Brunt's Tell the Wolves I'm Home, Alexandra Teague's lighthearted coming-of-age debut is perfect for anyone who's navigated the strange seas of adolescence--and lived to tell the tale. A.Z. McKinney is on the shores of greatness. Now all she needs is a boat. When the Sea of Santiago appeared overnight in a cow pasture in Arkansas, it seemed, to some, a religious miracle. But to high school sophomore A.Z. McKinney, it's marked her chance to make history--as its first oceanographer. All she needs is to get out on the water. Her plan is easier said than done, considering the Sea's eccentric owner is only interested in its use as a tourist destination for beachgoers and devout pilgrims. Still, A.Z. is determined to uncover the secrets of the Sea--even if it means smuggling saline samples in her bathing suit. Yet when a cute, conceptual artist named Kristoff moves to town, A.Z. realizes she may have found a first mate. Together, they make a plan to build a boat and study the Sea in secret. But from fighting with her best friend to searching for a tourist-terrorizing alligator (that may or may not be a crocodile), distractions are everywhere. Soon, A.Z.'s dreams are in danger of being dashed upon the shore of Mud Beach. With her self-determined oceanic destiny on the line, A.Z. finds herself at odds with everything she thought she knew about life, love, and the Sea. To get what she wants, she'll have to decide whether to sink or float . . . But which one comes first?
This book highlights the principles and technologies of flotation machine mainly used in mineral processing in detail. Froth flotation is one of the most important mineral processing techniques. Over 90% of the nonferrous minerals and 50% of the ferrous minerals in the world are treated using flotation: a complicated technique including procedures from chemistry, physics and multi-scale fluid mechanics. The book introduces readers to air-forced and air-induced flotation cells and discusses the various mechanical structures and working principles involved. A number of examples from industrial engineering practice are also discussed throughout the book, helping readers to better understand the technology and relevant equipment. The book is intended for researchers, professionals and graduate students in the fields of mining and mineral processing engineering.
The past 30 years have seen the emergence of a growing desire worldwide that positive actions be taken to restore and protect the environment from the degrading effects of all forms of pollution – air, water, soil, and noise. Since pollution is a direct or indirect consequence of waste, the seemingly idealistic demand for “zero discharge” can be construed as an unreal- tic demand for zero waste. However, as long as waste continues to exist, we can only attempt to abate the subsequent pollution by converting it to a less noxious form. Three major questions usually arise when a particular type of pollution has been identi?ed: (1) How serious is the pollution? (2) Is the technology to abate it available? and (3) Do the costs of abatement justify the degree of abatement achieved? This book is one of the volumes of the Handbook of Environmental Engineering series. The principal intention of this series is to help readers formulate answers to the last two questions above. The traditional approach of applying tried-and-true solutions to speci?c pollution p- blems has been a major contributing factor to the success of environmental engineering and has accounted in large measure for the establishment of a “methodology of pollution control. ” However, the realization of the ever-increasing complexity and interrelated nature of current environmental problems renders it imperative that intelligent planning of pollution abatement systems be undertaken.
Keeping pace with explosive developments in the field, Colloidal Science of Flotation reviews and updates the fundamentals of the bubble-particle collection phenomenon using a self-consistent approach that helps readers understand the hydrodynamic aspects of bubble-particle collection. The authors examine bubble rise velocity, water velocity around air bubbles, the thinning of intervening liquid films, the stability of particle-bubble aggregates, and macroscopic processes in froth. They also survey the applicability of emerging technologies in industrial flotation deinking, wastewater treatment, flotation of plastics, and improvements in minerals and coal flotation.
Handbook of Flotation Reagents: Chemistry, Theory and Practice is a condensed form of the fundamental knowledge of chemical reagents commonly used in flotation and is addressed to the researchers and plant metallurgists who employ these reagents. Consisting of three distinct parts: 1) provides detailed description of the chemistry used in mineral processing industry; 2) describes theoretical aspects of the action of flotation reagents3) provides information on the use of reagents in over 100 operating plants treating Cu, Cu/Zn, Cu/Pb, Zn, Pb/Zn/Ag, Cu/Ni and Ni ores.* Looks at the theoretical aspects of flotation reagents* Examines the practical aspects of using chemical reagents in operating plants* Provides guidelines for researchers and engineers involved in process design and development
This comprehensive reference examines all aspects of mineral processing, from the handling of raw materials to separation strategies to the remediation of waste products. It incorporates state-of-the-art developments in the fields of engineering, chemistry, computer science, and environmental science.
