Abstract
This paper is confined to a discussion of some of the experimental work by the Bureau of Mines metallurgical staff at the North Central Experiment Station, Minneapolis, and in particular to a progress report describing a sulfur dioxide-air roast process now under development on a small pilot-plant scale. Although individual steps of this process have been carried out successfully on a unitized basis, further investigation will be required on a variety of manganese-bearing materials from the Cuyuna range, Minnesota, to obtain the data necessary for designing a continuous process plant. Only the Cuyuna carbonate slate formation has been studied on a pilot-plant scale.
