Short summaries of 3,026 essays by Bill H. Ritchie, artist, teacher and visionary drawn from his journals written between 1969 - 2009. He structured the headings of each article according an imaginary place he calls "Emeralda," imagining ten islands on a lake where he, as a recipient of a mythical prize, is encouraged to write freely about anything that seems important to an artist, teacher and philosopher. Mindful of the use of new technologies, each essay summary has key index features which would allow a reader having a computer and optional CD/ROM to retrieve the full text of any article. Or, using freely chosen keywords of their own, find the articles which have those words in them.
This book is not designed to be an exhaustive work on mine wastes. It aims to serve undergraduate students who wish to gain an overview and an understanding of wastes produced in the mineral industry. An introductory textbook addressing the science of such wastes is not available to students despite the importance of the mineral industry as a resource, wealth and job provider. Also, the growing imp- tance of the topics mine wastes, mine site pollution and mine site rehabilitation in universities, research organizations and industry requires a textbook suitable for undergraduate students. Until recently, undergraduate earth science courses tended to follow rather classical lines, focused on the teaching of palaeontology, cryst- lography, mineralogy, petrology, stratigraphy, sedimentology, structural geology, and ore deposit geology. However, today and in the future, earth science teachers and students also need to be familiar with other subject areas. In particular, earth science curriculums need to address land and water degradation as well as rehabili- tion issues. These topics are becoming more important to society, and an increasing number of earth science students are pursuing career paths in this sector. Mine site rehabilitation and mine waste science are examples of newly emerging disciplines. This book has arisen out of teaching mine waste science to undergraduate and graduate science students and the frustration at having no appropriate text which documents the scienti?c fundamentals of such wastes.
