The Electrodeposition of Iron-Manganese Alloys

Although the alteration of properties resulting from the alloying of metals in their usual commercial forms has been extensively investigated, the field of electrodeposition of alloys is believed generally not to have received the atten­tion that it merits.

The Continuous Electrodeposition of Manganese

The object of this research was to produce a workable electrolytic cell for the continuous deposition of manganese from aqueous sulphate solutions and determine the critical factors in its oper­ation.

Concentration of Manganese Dioxide from Philipsburg, Montana

Imports of manganese ore probably supply a major proportion of the needs of the United States. Domestic production is reported to be higher than pre-war levels, but does not equal that of the peak production year of 1943. In 1946, the Anaconda Copper Mining Company ac­counted for 90 percent of the total shipments of mangan­ese nodules, and this company is the largest producer of domestic metallurgical ore in the United States.

A Mineral Dressing Study of the Benefication of Philipsburg Manganese Carbonate Ore

The beneficiation of rhodochrosite ore to the extent that it is suitable for nodulizing and subsequent use in the steel industry is intriguing. Such ores from certain mines is relatively easy to beneficiate, but the rhodo-chrosite ore from several deposits of the Philipsburg district has never been successfully up-graded by any of the several known beneficiating methods.

Broadband emission from a multicore fiber fabricated with granulated oxides

We demonstrate a multicore multidopant fiber which, when pumped with a single pump source around ∼800 nm , emits a more than one octave-spanning fluorescence spectrum ranging from 925 to 2300 nm . The fiber preform is manufactured from granulated oxides and the individual cores are doped with five different rare earths, i.e., Nd3+ , Yb3+ , Er3+ , Ho3+ , and Tm3+ .
