A variety of volcanic rock was recovered from the flanks of seamounts, guyots, atolls, and islands in the Ratak chain of the Marshall Islands on the U.S. Geological Survey cruise L984CP. The main objective of this cruise was to study the distribution and composition of ferromanganese oxide crusts. Preliminary results of managanese crust composition are reported by Schwab et al. (1985) and

Iron and Arsenic Speciation During As(III) Oxidation by

The redox state and speciation of the metalloid arsenic (As) determine its toxicity and mobility. Knowledge of biogeochemical processes influencing the As redox state is therefore important to understand and predict its environmental behavior. Many previous studies examined As(III) oxidation by various Mnoxides, but little is known concerning environmental influences (e.g., coexisting ions

Manganese dioxide Revolvy

Manganese dioxide Manganese(IV) oxide is the inorganic compound with the formula MnO. This blackish or brown solid occurs naturally as the mineral pyrolusite, which is the main ore of manganese and a component of manganese nodules. The principal use for MnO is for drycell batteries, such as the alkaline battery and the zinccarbon battery.[2]

high carbon ferromanganese production, parameters such as temperature, time and, charge basicity affect the manganese recovery. Generally, an increase in these parameters increases the extent of carbothermal reduction reactions, thus increasing the manganese recovery from charge. In this study, holding time, basicity of charge,

of alkaline batteries was incorporated into the charge for an electric furnace at Birmingham Steel's Birmingham, AL, plant. Addition of this scrap to the charge at rates of 1% to 3% was not found to affect properties of the steel produced and to give some benefit in reducing ferromanganese requirements.

Infrared absorption spectra of some Manganese Dioxide

The infrared absorption spectra of α‐, β‐, γ‐ and δ‐ MnO 2 prepared by different methods, were measured and discussed. It was found that the ratio of absorbancies of the bands at 595 ± 20 cm −1 und 535 ± 20 cm −1 (φ) is related to the amorphous content. Each preparation is characterized by a certain value of φ.

Major elements in manganese and iron oxides precipitated

The concentrations of alkaline earths and alkali metals in the iron oxide were lower than in the manganese oxides this is especially true of the alkali metals. On the basis of these results, mineralogical control on the major element composition and the chargebalancing ions of marine ferromanganese oxide deposits are discussed.
