Mica Beneficiation (open access)

Mica Beneficiation

From Abstract: "The micaceous schist ores yielded concentrates containing 95 to 98 percent mica, with recoveries ranging from 70 to 83 percent. Part 1 of this report summarizes the process development work and demonstrates the feasibility of producing commercial-grade mica concentrates. The report also includes details of commercial beneficiation and grinding of mica. Also included in part 2 of this report are details of commercial mica production, including methods of mining, recovering, and grinding mica, and information on the production, uses, and prices of mica."

Potash Salts from Texas-New Mexico Polyhalite Deposits: Commercial Possibilities, Proposed Technology, and Pertinent Salt-Solution Equilibria (open access)

Potash Salts from Texas-New Mexico Polyhalite Deposits: Commercial Possibilities, Proposed Technology, and Pertinent Salt-Solution Equilibria

From Introduction: "Figure 1 shows the location of sources that have been either exploited or seriously considered at one time or another, super-imposed upon a map indicating by small letters the order of consumption of K2O in the leading States; the amount used in these States, together with the percentage of the total consumption of potash used as fertilizer in the United States in 1939, is given in table 1. Figure 2 shows the domestic production and total consumption of potassium salts, in terms of tons of K2O, with the value per unit at the plants, for each year since 1913. Considered together, these two figures tell a significant story."

Progress Report of Southeastern Monazite Exploration, 1952 (open access)

Progress Report of Southeastern Monazite Exploration, 1952

Report about monzanite placers in streams of the western part of the Piedmont in Virginia, North Carolina, South Carolina, and Georgia. The objective of the report is to describe local monazite deposits, to determine geologic controls of monazite placers in the southeastern Piedmont, and to evaluate placer potentialities of the area.

Uranium in the Southern United States (open access)

Uranium in the Southern United States

From introduction: In this study on raw material sources of uranium the Southern Interstate Nuclear Board has catalogued all known occurrences of uranium and some references to thorium in a 17-state area (P1. 1). These occurrences have been evaluated as potential sources of uranium by the State Geological Surveys and the consultant group of SINB. Favorability guides have been applied to the known occurrences and recommendations have been made for future action by the states involved, federal agencies, or by industry. State recommendations are included in state-by-state summaries. The state reports were written either by personnel of the State Geological Surveys or were abstracted from State geological survey data by members of the consultant group...The purpose of this study was to compile information on and systematically assess uranium and other radioactive occurrences in the region. The SINB undertook the project because of its statutory, interstate capability as an extension of government in each of the 17 states, an arrangement that lends itself effectively to this cooperative undertaking.
