Main purpose of this study was to investigate the production of high carbon
ferromanganese by smelting a manganese ore located in Erzincan. Time, charge
basicity, fluorspar addition and coke to ore weight ratio were used as experimental
variables.
After characterization of the ore, a mixture of 100 grams of uncalcined
manganese ore and carefully weighed amounts of coke powder, lime, fluorspar and
scrap iron were put into a conical graphite crucible. The graphite crucible with its
contents was covered with a graphite lid and placed in an electronically controlled
muffle furnace. The furnace was heated to 1600 oC and held at this temperature for a
predetermined time and cooled to room temperature. The crucible was taken out of
the furnace and the metal and slag phases formed were removed from the crucible by breaking the crucible and carefully weighed. Finally, the metal and slag phase were
subjected to chemical analysis.
The experimental results show that Erzincan manganese ore can be used in
the production of high carbon ferromanganese.
