Africa’s dire need to industrialize is universally acknowledged and it is evident that the continent’s vast mineral resources can catalyze that industrialization. This requires the promotion of local beneficiation and value addition of minerals to yield materials on which modern Africa’s industry and society can rely. This book is, therefore, about transforming Africa’s comparative advantages in minerals into the continent’s competitive edge regarding materials. Mineral beneficiation and value addition form the basis and provide opportunities for mineral-driven Africa’s industrialization. The scope of the book is three-fold with inter-connected relationships: Information, Technical, and Policy oriented. It will be a useful reference material for mining undergraduate students on beneficiation and value addition of each of the minerals found in Africa. The book, while presenting a broad overview of beneficiation and value addition of Africa’s minerals, provides crucial starting material for postgraduate research students and R&D institutions who wish to delve into more advanced methods of extraction and utilization of mineral-derived materials that are in Africa for the purpose of industrialization of the continent.

The Coeur d'Alenes, a twenty-five by ten mile portion of the Idaho Panhandle, is home to one of the most productive mining districts in world history. Historically the globe's richest silver district and also one of the nation's biggest lead and zinc producers, the Coeur d'Alenes' legacy also includes environmental pollution on an epic scale. For decades local waters were fouled with tailings from the mining district's more than one hundred mines and mills and the air surrounding Kellogg, Idaho was laced with lead and other toxic heavy metals issuing from the Bunker Hill Company's smelter. The same industrial processes that damaged the environment and harmed human health, however, also provided economic sustenance to thousands of local residents and a string of proud, working-class communities. Living with Leadendeavors to untangle the costs and benefits of a century of mining, milling, and smelting in a small western city and the region that surrounds it.

Humans first used carbon as chars from firewood in ritual paintings and primitive metallurgical processes. Natural forms of carbon have been known since antiquity, yet the knowledge of the carbon element in chemistry and its technical applications on a larger scale are a relatively recent development. The industrial revolution in Europe two centuries ago led the way to the numerous applications of these graphitic forms that are still used today. Graphite and Precursors features short tutorial articles on different topics related to the science and technology of carbons intended for engineers, students of Materials Science and scientists who are seeking a fundamental understanding without "reinventing the wheel." This first volume of the World of Carbon book series focuses on graphite and its precursors, including its origin and various implications. The basic properties of hexagonal graphite are developed, and several theoretical and experimental approaches explain why this crystalline solid is fascinating in solid state physics. Also featured are the numerous applications connected to thermal, mechanical and chemical graphites, as well as their various industrial uses in polycrystalline form. Finally, carbon precursors are introduced.

Primal man benefited from a powerful cure-all that continually coursed through his blood vessels. This substance -- made in the liver -- protected him from an overwhelming list of health challenges that, until recently, were rare causes of death. Due to a genetic error of metabolism, the vast majority of us no longer produce this panacea, making us increasingly susceptible to cancer, heart disease, osteoporosis, dementia, diabetes, and many other very costly, and often fatal maladies. Thousands of scientific studies prove that sufficient quantities of this substance in the bloodstream still provide the same protective and curative properties experienced long ago. Dr. Levy cites over a thousand of these published reports as he relates the history and science of the "primal panacea" in an easy-to-read and entertaining way. He also relates simple and powerful ways to boost blood levels to those once enjoyed by our ancient ancestors. Primal Panacea is chock full of proof, resources, and practical how-to. It will save you money, it will greatly improve your odds for a long and healthy life -- we guarantee it
