Book Description
Mining and mineral processing operations in Canada produce about 650 x 106 metric tons of mineral waste annually. This waste is composed of broken rock from open pits and underground mines, coarse mill rejects from screening and heavy media separation processes, and fine mill tailings from screening, magnetic separation, and flotation processes. Most wastes have limited potential for reuse because of their high impurity content or remote location. However, some are favorably located and of interest because of contained metals and minerals or inherent physical and chemical characteristics. Waste utilization is an attractive alternative to disposal because disposal costs and potential pollution problems are reduced or even eliminated and resources are conserved. Waste rock could be used as landfill, in roadbed and dam construction, as railroad ballast, as aggregate in concrete and asphalt mixes, and, for the finer sizes of waste, as construction sand, as an additive to concrete and asphalt mixes, in brick and block manufacture, in the manufacture of thermal insulation, for the recovery of valuable metals or minerals, and as mineral fillers. Examples of the commercial utilization of a number of such wastes are noted.

Book Description
"This report provides background information on waste rock and mill tailings in the Atlantic Provinces where more than 45 x 106 t of such wastes are produced annually. Data on the occurrence, mineralogy, petrography, and physical and chemical characteristics of wastes from 17 operating mines are provided in tabular form for three principal types of mines - metal, non-metallic or industrial mineral, and coal. Potential uses for these wastes are noted along with relevant research"--Synopsis, p. i.

Book Description
"This report provides background information on waste rock and mill tailings in the Prairie Provinces where more than 90 x 106 t of such wastes are produced annually. Data on the occurrence, mineralogy, petrography, and physical and chemical characteristics of wastes from 21 operating mines are provided in tabular form for 4 principal types of mines - metal, uranium, non-metallic or industrial mineral, and coal. Potential uses for these wastes are noted along with relevant research"--Synopsis, p. i.

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.
