...SAG MILL GRINDING DESIGN VERSUS GEOMETALLURGY – GETTING IT RIGHT FOR COMPETENT ORES J Starkey1 and P Scinto2 ABSTRACT Smarter processing for the future, in the area of SAG mill design involves accurate grinding test data, completing final mill design in less than three months, and at a cost of less than $80 000 US. More detailed variability testing on the other hand takes longer, is more expensive, and is used for throughput optimization for an existing or newly purchased mill. This paper shows that SAGDesignTM testing is excellent for new SAG plant design due to relatively low cost per test and the ability to do more testing for a limited budget on larger projects. It also briefly examines a way to develop proper geometallurgical ore hardness information on every block in the mine model, from the more detailed analysis data. Keywords: comminution tests, bond work indices, grinding mill design, database, ore hardness measurements, SAGDesign test, JK dropweight test INTRODUCTION The selection of SAG and ball milling sizes and configurations for new projects is complicated by the fact that grinding characterisation data is typically limited at best. The use of this grinding characterisation data by different grinding consultants, to specify totally different equipment and or configurations for the same project is becoming a major concern for the industry. This is highlighted by the fact that a number of new projects are following the concept of selecting the largest proven equipment...

...Marie Curie: A martyr to Physics As a symbol of the human quest for knowledge and the ability to sacrifice oneself for a higher cause, Marie Curie helped shape the world as we know it with her discoveries and personal interest in the welfare of mankind. Born in 1867, of Polish parents, Marie garnered an early appreciation for education, with her father, a mathematics and physics professor, and mother, a pianist, stressing the importance of diligent study. At eleven, Marie was left with her father as her sole guardian after the tragic death of her mother to tuberculosis. As a result, Marie became increasingly interested in physics, graduating at the top of her high school class at a mere fifteen years of age. Post-graduation, Marie worked for eight years as a private tutor and governess to earn sufficient money to attend the Sorbonne University in Paris, having been denied admittance to the University of Warsaw on account of being a woman. In what little spare time she was left, Marie pursued a study of mathematics and physics, while attending what many dubbed “a poorly organized school” conducted by Polish professors in defiance of the Russian edict banning their organization, composed of “a group of men and women who tried to quench their thirst for knowledge in secret sessions” (Quinn 1). In1891, Marie finally realized the first of her goals, leaving for Paris to attend the Sorbonne. Despite poor living conditions, a distinct lack of food and sleep, which rendered...

...Title: Technology and society : some insights on the development of metallurgy in the Southern Levant in the light of new dates of slag deposits Author: Ben-Yosef, Erez Acceptance Date: 01-01-2008 Series: UC San Diego Electronic Theses and Dissertations Degree: M.A., UC San Diego Permalink: http://escholarship.org/uc/item/03f2f3vx Local Identifier: b6636008 Abstract: An ongoing project for reconstructing the behavior of the geomagnetic field intensity during the last seven millennia has yielded several new dates for archaeometallurgical sites in the Southern Levant. These dates shed new light on the dawn of metallurgy in the region as well as on the quality of technological development and its relation to social and political structures. This paper introduces the methodology and concepts behind the archaeomagnetic project as well as the principles of the applied dating technique. In addition, the paper presents the archaeomagnetic results, discusses the alternative dating of several archaeometallurgical sites and explores the implication of these results on our understanding of the interaction between technology and society in the past. For the latter, the results particularly challenge the "Standard View of Technology" (Pfaffenberger, 1992), and suggest a complex, nonlinear evolution of copper industry in the Southern Levant eScholarship provides open access, scholarly publishing services to the University of California and delivers a dynamic research platform to scholars...

...EXTERNAL ANALYSIS of the PHILIPPINES Filipinos are food lover. Filipinos do not consider it a meal if rice is not served. Plain steamed rice is the basis of the diet. Three crops a year are harvested to provide enough rice for the population, and the government keeps surpluses stored for times of drought. Salt water and freshwater of fish and shellfish are eaten daily, served either fresh or salted. Fish, chicken and pork are usually fried, although people are becoming more health-conscious and often choose alternative methods of cooking. Garlic is added to food because it is considered healthful. Filipino food is not spicy. All food is cooked on gas burners or wood or charcoal fires and is allowed to get cold before it is eaten. Rice is cooked first, since it takes longer. When it is ready, rice will be placed on the table while the next items of the meal are prepared and served. Table knives are not used. Forks and spoons are used for dining. The food is eaten from a spoon. The traditional method of placing food on a banana leaf and eating with one's hands is also used throughout the country. It is acceptable to eat food with one's hands at restaurants as well as in the home. Breakfast is served at 6 A.M. and consists of food left over from the night before. It is not reheated. Eggs and sausage are served on special occasions. Small buns called pan de sol may be purchased from vendors early in the morning. At midmorning and in the afternoon, people eat merienda.

...Data Mining Nabeel Ahmed University of Northern Virginia Abstract ‘The vein of research data is almost always richer than it appears to be on the surface, but it can only be of value if mined.—Morris Rosenberg’ (AGOSTA, 2000) Recent years, Data Mining has become hot topic of enterprises. More and more companies intend to introduce data mining techniques. One report from the United States treats data mining as one of the ten favorable fields in the 21st century, of which by means shows its importance. Generally speaking, data mining are often applied in those fields, such as insurance and finance industries, retailing and direct marketing industries, communication industry, manufacturing industry and Medical service industry, etc. The data related to management decision making has been accumulating surprisingly quickly because of the improvement in high technology. As the byproduct of internet, e-commerce, e-banking, pos system, barcode scanner and intelligent robot, the acquirement of electronic data has already become cheap and existing everywhere. These data are normally stored in data warehouse and data marts to provide assistance for management decision-making. Data mining is a fast growing field, its main target is to develop some techniques to assist the managers in intelligent analyzing and utilizing mass data. Data mining was already being reported in successfully utilized in the aspects of credit rating, fraud detection, database marketing, customer relationship...

It also exa mines the Malay sian labo ur mark et situation a nd trends in salary and wage administration together with the role of unions in compensation determination. INTRODUCTION Malaysia is a country of more than 20 million located at the southernmost tip of mainland Asia. Besides being a leading exporter of commodities such as natural rubber, tin, palm oil, timber, petroleum, and natural gas, Malaysia is also one of the world’s leading exporters of electronic semicond uctors, roo m air-cond itioners, and a udiovisual e quipmen t. Prior to July 199 7, Asia was seen as a region exemplifying success in economic growth and development. Between 1991 to 1996, the Malaysian econom y grew at an ave rage rate of m ore than 8% . Howev er, Mala ysia could no t shield itself from being negatively impacted by the 1997 Asian Financial Crisis where the nation suffered a 7.5% c ontraction in its Gross D omestic P roduct (G DP) in 1 998. In 2000, M alaysia had a workforce (defined as persons between 15-64 years old) of slightly above 9 million. About 60% of the workforce were below 35 years of age. Union members accounted for about 8.15% of the labour force. Unemployment was reported at 3% of the labor force, and foreign workers accounted for one out of every seven jobs (Malaysia 1996-1998, 1996 ). This scenario shapes the Malaysian...

...Acknowledgments ix Acknowledgments This book owes a great deal to the mental energy of several generations of scholars. As an undergraduate at the University of Cape Town, Francis Wilson made me aware of the importance of migrant labour and Robin Hallett inspired me, and a generation of students, to study the African past. At the School of Oriental and African Studies in London I was fortunate enough to have David Birmingham as a thesis supervisor. I hope that some of his knowledge and understanding of Lusophone Africa has found its way into this book. I owe an equal debt to Shula Marks who, over the years, has provided me with criticism and inspiration. In the United States I learnt a great deal from ]eanne Penvenne, Marcia Wright and, especially, Leroy Vail. In Switzerland I benefitted from the friendship and assistance of Laurent Monier of the IUED in Geneva, Francois Iecquier of the University of Lausanne and Mariette Ouwerhand of the dépurtement évangélrlyue (the former Swiss Mission). In South Africa, Patricia Davison of the South African Museum introduced me to material culture and made me aware of the richness of difference; the late Monica Wilson taught me the fundamentals of anthropology and Andrew Spiegel and Robert Thornton struggled to keep me abreast of changes in the discipline; Sue Newton-King and Nigel Penn brought shafts of light from the eighteenthcentury to bear on early industrialism.
