Synopsis Alluvial Prospecting and Mining by : S. V. Griffith

Alluvial Prospecting and Mining (Second Revised Edition) focuses on the emergence of improved mining techniques and methods used in the excavation of alluvial deposits. The book first offers information on the prospecting methods, sampling, and valuation. Discussions focus on preliminary systematic prospecting, drilling in difficult ground, supervision of drilling, rate of excavation, pitting and drilling compared, sampling of bore holes, and calculation of reserves. The publication then examines water supply, including earth dams, spillways, leats, ditches, or canals, and design of pipelines. The manuscript ponders on sluicing and dry concentration of minerals. Topics include rock pavements, undercurrents, false bottoms, glean up, tailings, ground sluicing, water required, exploitation of plants, electrostatic separation, and high intensity magnetic separators. The book also reviews forward preparation of overburden, hydraulic mining, and gravel pumping. The publication is a dependable reference for miners and readers interested in alluvial prospecting and mining.

Synopsis Quarrying Opencast and Alluvial Mining by : John Sinclair

Quarrying and all other branches of surface mining rather than diminishing in importance have become of more and more consequence economically, industrially and particularly with the depletion of high-grade deep-mined mineral reserves. Low-grade minerals require low cost extraction and this in many cases necessitates very expensive mechanized equipment with the cost of individual units running into millions of pounds in the case of large scale operations with high productivity. There has been, and there still is, a tendency for the smaller single quarries to be amalgamated into groups with large financial resources and therefore with the ability to purchase these expensive machines so necessary to make operations viable. This in turn requires wider administrative and technical knowledge in executives of these groups and as these often handle a wide range of products from widely differing systems of working, this technical knowledge should embrace the exploitation of many different types of deposits. There is, at present, a great dearth throughout the world of such qualified executives as is apparent from advertisements of vacancies in the technical press. It would appear that these industries offer an attractive career to the widely qualified and experienced technologist in these fields. This book deals with methods of working in the surface extractive indus tries, quarry management and power supply-but does not deal with related ancillary processes except where these affect quarrying operations.
