Evolutionary and Revolutionary Technologies for Mining
Author: National Research Council
Publisher: National Academies Press
ISBN: 0309169836
Category : Science
Languages : en
Pages : 102
Book Description
The Office of Industrial Technologies (OIT) of the U. S. Department of Energy commissioned the National Research Council (NRC) to undertake a study on required technologies for the Mining Industries of the Future Program to complement information provided to the program by the National Mining Association. Subsequently, the National Institute for Occupational Safety and Health also became a sponsor of this study, and the Statement of Task was expanded to include health and safety. The overall objectives of this study are: (a) to review available information on the U.S. mining industry; (b) to identify critical research and development needs related to the exploration, mining, and processing of coal, minerals, and metals; and (c) to examine the federal contribution to research and development in mining processes.

Basics of Metal Mining Influenced Water
Author: Virginia T. McLemore
Publisher: SME
ISBN: 9780873352598
Category : Science
Languages : en
Pages : 116
Book Description
Basics of Metal Mining Influenced Water is a must-read for planners, regulators, consultants, land managers, students, researchers, or others concerned about the environmentally sound management of metal mine wastes and drainage quality. The first of a series of six handbooks on technologies for managing metal mine and metallurgical process draining, this book offers a unique, comprehensive perspective on the subject. Unlike other texts that focus primarily on acid drainage from coal mines, the authors examine both acidic and neutral pH waters that can be hazardous to the environment. Planning a new mine in today s increasingly contentious regulatory and political environment demands a different philosophy. Basics of Metal Mining Influenced Water takes an innovative, holistic approach by considering all aspects of the mine life cycle, including closure. Written by a team of experts from state and federal governments, academia, and the mining industry, Basics of Metal Mining Influenced Water also discusses the major physical and chemical relationships between mining, climate, environment, and mine waste drainage quality. The authors have included an extensive glossary defining hundreds of technical terms for easier reading and understanding.

Mining and Engineering Methods and Costs of the Hanover Bessemer Iron & Copper Co., Fierro, N. Mexico
Author: Lloyd M. Kniffin
Publisher:
ISBN:
Category : Copper mines and mining
Languages : en
Pages : 32
Book Description
This paper is one of series being prepared by the United States Bureau of Mines on mining methods, practices, and costs in the various mining districts of the United States. It describes the mine of the Hanover Bessemer Iron & Copper Co. at Fierro, Grant County, N.M., which is the only operating iron mine in the southwestern part of the United States. This mine is in a district noted for the great variety of ores that it produces. Within a small area, as shown is Figure 1, there are noteworthy deposits of nearly all the common metals. The ore occurs in lenticular masses dipping at about 50°. An underhand stoping method has been developed that requires but a very small amount of handling of ore. As the ore is very irregular in iron content and also in the distribution of the impurities--chiefly sulphur, silica, and magnesia--a method has to be used that will permit selective mining and will also allow ore and waste to be taken out separately as conditions change. A magnetic cobbing plant raises the grade of the ore shipped about 10 per cent. Nealy all of the iron ore is shipped to Pueble, Colo., a distance of 694 miles, where it is smelted by the Colorado Fuel & Iron Co. The mine is not a large producer, as the long distance from blast furnaces limits its output. In recent years the annual shipments have amounted to about 200,000 tons. The property is noteworthy chiefly on account of this long transportation by rail and the economical methods that have been developed to make the operation profitable. About 175 men are employed.
