Effects of low concentrations of sulfur dioxide on oxidized manganese ores at elevated temperatures

Abstract

"Although there are large quantities of manganese ore in the United States, most of it is low-grade and cannot be used for the production of ferromanganese. Much government and private research has been done to concentrate the domestic low-grade ores but many problems have been encountered. A large number of treatments have been found necessary for ores from various sections of the country. Low-grade ores have been sulfated with sulfur dioxide in the gaseous state at elevated temperatures and the soluble manganous sulfate extracted with water. This gave a solution of manganous sulfate that may be used for the recovery of manganese by many available methods. It was believed that with proper conditions of temperature, concentration of sulfur dioxide, and other variables, it would be possible to use a non-commercial supply of sulfur dioxide and obtain a soluble manganese salt of commercial significance. These factors led to the selection of this subject as a research problem"--Introduction, page 1-2.
