Download or read book Managing Gold Mine Production and Operation written by Arega Yirdaw and published by Independently Published. This book was released on 2023-01-15 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author has dedicated many years of his life to the reconstruction of this work as manager of a gold mine with a view that this book would serve as a practical guide for young practitioners as well as for those who manage gold mining operations in Ethiopia and elsewhere. As it is written in clear and lucid language, it is helpful and convenient for practitioners and professionals to make utmost use of it as a quick referencing guide in their efforts to maximize the quantity and quality of gold mining production. The sharing of experiences of leaders and managers in such a manner will have a profound contribution to the sustainable growth of professions as well as institutions. This act is worth emulating. Based on the author's engineering, science, aviation, and aerospace background, the author has provided in great detail how gold is processed from ore/rock to marketable bullion bars for the benefit of all those engaged in gold mine operations. The practical examples and the detailed description of gold processing with proper mitigation to potential impacts on the community and environment make the book an excellent management/leadership tool for practitioners in the gold mine industry.

Download or read book Artisanal Small Scale Gold Mining written by Katherine von Stackelberg and published by World Bank Publications. This book was released on 2022-06-13 with total page 125 pages. Available in PDF, EPUB and Kindle. Book excerpt: This framework document provides a pragmatic approach for designing representative studies and developing uniform sampling guidelines to support estimates of morbidity that are explicitly linked to exposure to land-based contaminants from small-scale artisanal gold mining activities. A primary goal is to support environmental burden of disease evaluations, which attempt to attribute health outcomes to specific sources of pollution. The guidelines provide recommendations on the most appropriate and cost-effective sampling and analysis methods to ensure the collection of representative population-level data, sample size recommendations for each contaminant and environmental media, biological sampling data, household survey data, and health outcome data. This framework focuses on small-scale artisanal gold mining (ASGM) activities that are known to use and generate mercury (Hg) as well as other metals, such as arsenic (As) and lead (Pb), depending on the specific ores being mined. A particular concern with Hg is the conversion to methylmercury (MeHg) in aquatic environments, leading to bioaccumulation and biomagnification in fish that may be locally consumed. Exposure to Hg, MeHg, and Pb are strongly associated with neurodevelopmental health outcomes in children. Exposure to Hg and MeHg are also associated with neurological illnesses in adults. Exposures to Pb are associated with renal outcomes in children and adults, and cardiovascular outcomes in adults. Exposure to As are associated with neurodevelopmental health outcomes in children, arsenicosis and skin disorders in children and adults, and potential cancers in adults, including skin, bladder, and lung. The primary objective of this framework is to guide research to assess the relationship between environmental contamination, exposures, and health outcomes related to a subset of contaminants originating from ASGM activities for particularly vulnerable populations (such as children) and the general population within a single household in the vicinity of ASGM sites in low- and medium-income countries. To achieve this objective, biomonitoring and health outcome data are linked to household survey and environmental data (for example, soil, dust, water, agricultural products, fish) at the individual level from an exposed population compared to individuals from an unexposed (reference) population. Data on exposures and health outcomes in the same individual across a representative set of individuals is required to support an understanding of the potential impact of ASGM activities on local populations. These guidelines can also assist in building local capacity to conduct environmental assessments following a consistent methodology to facilitate comparability across ASGM sites in different geographic areas. Sampling strategies and methods are prioritized given information needs, resource availability, and other constraints or considerations. The framework includes a number of supporting appendixes that provide additional resources and references on relevant topics.

Download or read book The Gold Resources and the Gold Mining Industry of the Far Eastern Republic written by Various and published by Pringle Press. This book was released on 2007-10 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: PREFACE. THE Author of this very practical treatise on Scotch Loch - Fishing desires clearly that it may be of use to all who had it. He does not pretend to have written anything new, but to have attempted to put what he has to say in as readable a form as possible. Everything in the way of the history and habits of fish has been studiously avoided, and technicalities have been used as sparingly as possible. The writing of this book has afforded him pleasure in his leisure moments, and that pleasure would be much increased if he knew that the perusal of it would create any bond of sympathy between himself and the angling community in general. This section is interleaved with blank shects for the readers notes. The Author need hardly say that any suggestions addressed to the case of the publishers, will meet with consideration in a future edition. We do not pretend to write or enlarge upon a new subject. Much has been said and written-and well said and written too on the art of fishing but loch-fishing has been rather looked upon as a second-rate performance, and to dispel this idea is one of the objects for which this present treatise has been written. Far be it from us to say anything against fishing, lawfully practised in any form but many pent up in our large towns will bear us out when me say that, on the whole, a days loch-fishing is the most convenient. One great matter is, that the loch-fisher is depend- ent on nothing but enough wind to curl the water, -and on a large loch it is very seldom that a dead calm prevails all day, -and can make his arrangements for a day, weeks beforehand whereas the stream- fisher is dependent for a good take on the state of the water and however pleasant and easy it may be for one living near the banks of a good trout stream or river, it is quite another matter to arrange for a days river-fishing, if one is looking forward to a holiday at a date some weeks ahead. Providence may favour the expectant angler with a good day, and the water in order but experience has taught most of us that the good days are in the minority, and that, as is the case with our rapid running streams, -such as many of our northern streams are, -the water is either too large or too small, unless, as previously remarked, you live near at hand, and can catch it at its best. A common belief in regard to loch-fishing is, that the tyro and the experienced angler have nearly the same chance in fishing, -the one from the stern and the other from the bow of the same boat. Of all the absurd beliefs as to loch-fishing, this is one of the most absurd. Try it. Give the tyro either end of the boat he likes give him a cast of ally flies he may fancy, or even a cast similar to those which a crack may be using and if he catches one for every three the other has, he may consider himself very lucky. Of course there are lochs where the fish are not abundant, and a beginner may come across as many as an older fisher but we speak of lochs where there are fish to be caught, and where each has a fair chance. Again, it is said that the boatman has as much to do with catching trout in a loch as the angler. Well, we dont deny that. In an untried loch it is necessary to have the guidance of a good boatman but the same argument holds good as to stream-fishing...

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Model of an Arizona Gold Mine This model represents a small gold mine of med ium richness in a vertical quartz vein six feet wide. The vein and mine workings are presented in section, that is, as they would appear if they were cut through along the center of the vein and one-half removed. This model is intended to illustrate the ordinary features present in some form in the great majority of all metal mines and to show the orderly manner in which mines are developed and the ores extracted. Great diversity in the nature and structure of ore deposits compels a corresponding variety in the details of workings by means of which the ores of these de posits are extracted. However diverse these details may be, they all may be grouped as parts of major features which are common to nearly all metal mines. In this respect these excavations resemble the more familiar structures on the surface. As build ings, however much as they may differ in appearance, are all built up of units, as walls, floors, windows and doors, so these underground workings are composed of groups of such units, as drifts, cross-cuts, stopes, raises, etc. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

Book excerpt: Excerpt from The Organization of Gold Mining Business, 1897: With Specimens of the Departmental Report Books and the Account Books The "Departmental Report Books" required may be suitably made of the same size of paper as the Specimens shewn in the following pages. The "Account Books" should be larger in size than the Specimens, preferably of what is known as demy paper. The copies of the Departmental Reports and Accounts, for transmission monthly to the Head Office, should be on the same Form and size of paper as the originals. This Book should always be in duplicate - one copy at the Mine and one at the Head Office of the Company - for reference purposes. Any local variations which are authorized by the Head Office should be noted in both the Books. Convenient spaces have been left for this purpose, and for other MS. notes. The system is applicable to Transvaal and Australian Gold Mining, in both of which it has been used: but in the hands of intelligent officers no difficulty should be found in adapting it to the requirements of other countries.
