PREPARING METHOD OF SINTERED NEUTRAL MANGANESE ORE HAVING SUPERIOR USABILITY AND SINTERED NEUTRAL MANGANESE ORE

摘要

The present invention relates to a manufacturing method for a neutral sintered manganese ore with excellent usability in a ferromanganese electric furnace and a neutral sintered manganese ore manufactured by the same. According to the present invention, the manufacturing method for a neutral sintered manganese ore includes: a step of obtaining a neutral mixed fine ore which is a mixture of basic manganese fire ore and an acidic manganese fine ore, by mixing the basic manganese fine ore and the acidic manganese fine ore so that a weight ratio of CaO/SiO_2 is in a ratio of 0.5-2.0 after being sintered; and a sintering step. According to the present invention, a basicity ratio of the neutral sintered manganese ore is optimized, and the neutral sintered manganese ore is suitable to be used for the ferromanganese electric furnace. According to the present invention, the Fe element ratio of the neutral sintered manganese ore is optimized. So, the neutral sintered manganese ore is suitable to be used for the ferromanganese electric furnace.
