Report issued by the U.S. Bureau of Mines discussing the development and use of fire doors in non-coal mines. As stated in the abstract, "this report discusses current fire-door technology in the context of the underground mine environment and the design, fabrication, lab testing, and in-mine field testing of a mine-worthy fire door" (p. 1). This report includes tables, illustrations, and photographs.

Report discussing the production and export or chromite from the U.S.S.R, including an overview of the industry (raw material base, mining and processing facilities, foreign trade, and policies and programs controlling its operations) as well as observations on the outlook for the future.

Report presenting a study of the Soviet manganese industry, which is intended to aid in assessing the present and future role of the U.S.S.R. on the world supply. Information is provided on reserves, mining, technology, ferroalloy production, trade, and consumption.

Bulletin issued by the U.S. Bureau of Mines containing a compilation of thermodynamic data regarding sulfides. There are tables for standard heat capacities (includes equations), standard entropies, high-temperature relative enthalpies (includes equations), Gibbs energy functions, enthalpies of formation (includes equations), Gibbs energies of formation (includes equations) and logarithms of the equilibrium constants. Documentation in the introduction explains how the tables are organized and use of the data.

From introduction: During the spring and fall of 1979 the U.S. Bureau of Mines made a mineral investigation of the North End Roadless Area, including a literature search, a search of claim records in the Cochise County courthouse and the State office of the Bureau of Land Management, a search for mining claims and mineralized zones, and examination of known mines and prospects. Local residents and officials of mining companies the U.S. Forest Service, and Arizona State government agencies provided information regarding mining activity and mineral deposits.

From introduction: During 1981 the Bureau of Mines conducted a field investigation of the Bureau of Land Management's Lime Hills, Narrows, and Sand Cove Wilderness Study Areas (WSA's), Mohave County, Arizona as part of a joint effort with the Geological Survey to make a mineral survey of the area. Surface workings and outcrops were examined and samples taken from rock sections that appeared to represent most of the mineralized area. Complete analytical results and sample descriptions are available for public inspection at the Bureau of Mines, Intermountain Field Operations Center, Building 20, Denver Federal Center, Denver, Colo. Part of the area also was examined and sampled in 1979 by L. W. Hamm, Bureau of Mines (Villalobos and Hamm, 1980), during a mineral resource study of the Paiute Primitive Area.

From introduction: While much has been written concerning nodule resources, conceptual mine-process systems, and economics, no published work is available which addresses the question of profitability of mining a specific nodule deposit. Therefore, the purposes of this report are to analyze available information on deposits in the northeast Pacific high-grade zone in an attempt to identify areas of high grade and abundance, and determine their minability and profitability based on existing technology and economics. A final purpose, irrespective of profitability, is to analyze the potential beneficial impacts nodule production could have on the U.S. supply of nickel, copper, cobalt, and manganese.

From foreword: This report is on the Arnold Mesa RARE II Further Planning Area, Yavapai County, Arizona.

This report presents the results of the mineral survey of the Sierra Ancha Wilderness and Salome Study Area conducted by the U.S. Bureau of Mines. A combined summary report of work done by the U.S. Geological Survey and U.S. Bureau of Mines has been previously published.

From summary: The Harquahala Mountains BLM Wilderness Study Area is in the Basin and Range physiographic province of west-central Arizona. The present study covers 24,735 acres of the 72,675 acre wilderness study area, preliminary recommended as suitable for inclusion in the National Wilderness Preservation System in La Paz and Maricopa Counties, Arizona. During the winter of 1983-84, under authority of the Federal Land Policy and Management Act (Public Law 94-579), the Bureau mapped and sampled mines and prospects in and near the WSA to determine the mineral resources present.

From summary: In January-April 1984, the Bureau of Mines conducted a mineral survey of the Lower Burro Creek Wilderness Study Area as required by Federal Land Policy and Management Act (Public Law 94-579, October 21, 1976). The Lower Burro Creek Wilderness Study Area comprises 21,700 acres in southeastern Mohave and Yavapai Counties, Arizona.

From summary: In January-April 1984, the Bureau of Mines conducted a mineral survey of the Lower Burro Creek Wilderness Study Area as required by Federal Land Policy and Management Act (Public Law 94-579, October 21, 1976). The Lower Burro Creek Wilderness Study Area comprises 21,700 acres in southeastern Mohave and Yavapai Counties, Arizona. Mines and prospects are located on deposits and (or) occurrences of gold, bentonite, magnesite, and agate in the eastern and southeastern part of the study area.
