دانلود کتاب Ninth Mill Operators' Conference Proceedings 2007

That the Mill Operators’ Conference series has reached its ninth inning is a testament to the regard with which it is held by mineral processing operators around Australia and overseas. While more formal forums play an important role in the industry, the Mill Operators’ Conference has tended to lean as much, if not more, toward practical experiences in operating plants as it does to purely academic research. These 2007 conference proceedings provide the mineral processing industry with the opportunity to improve on two fronts; by continuing to improve throughput and metal production from current best practice, or by looking to improve efficiencies, and minimize the trade-off. Whether this is done through research leading to new or improved technology, or simply through showing how to do things more safely or more efficiently doesn’t matter; the result is positive for the operating sites in both cases. It is hoped that in the selection of papers compiled in this volume, the reader will find at least one idea that can be used or developed further to improve their organization’s business.
