Oxidation of Pyrite to Maghemite.
For Reference Only At Bureau Libraries :143 pages
Investigation of the alteration processes of pyrite revealed that several magnetic chemical species are formed, depending upon oxygen and sulfur fugacities, temperature, and ph. Oxidation in both a dry and aqueous environment was studied. The primary purpose of the work included attempts to understand the processes wherein magnetic substances can be created from pyrite with the ultimate goal of aiding in the magnetic separation of pyrite, and hence sulfur from coal. This report presents a detailed description of the investigation.
