|dc.description.abstract||The object of this investigation was to find a general and
profitable method for the purification and concentration of low
grade Alabama manganese ores, which had little, if any, value
in their present form.
The various samples of Alabama manganese ore examined
on a small scale were readily attacked by even weak solutions
of sulphur dioxide in water and apparently a process applied by
the Bureau of Mines to western manganese ores could be applied
to Alabama ores.
The above process consists of the solution of the manganese
ore in a solution of sulphur dioxide in water and the resulting
solution of manganese sulphate is converted into an oxide of
of manganese by calcination.
The optimum conditions for the extraction of the manganese
have been determined. These, on a plant scale, probably would
be somewhat different.
The probable large scale process has been described and
the cost of the process estimated. The treatment of ores containing
at least twenty-five per cent manganese apparently
shows considerable promise.||en_US
