PURPOSE: A method for manufacturing pretreatment reduced briquette of manganese ore is provided to reduce manufacturing costs for metal manganese and wolfram manufacture and to recycle special steel and high grade steel. CONSTITUTION: A method for manufacturing pretreatment reduced briquette of manganese ore comprises next steps. Manganese inclusion is sorted from rhodochrosite(S10). A manganese mineral is crushed in 10mesh(2mm). The mixed forming of the selected manganese inclusion is manufactured(S20). Bituminous coal is mixed the manganese inclusion as 5~15 weight%. Furnace slag is mixed in the manganese inclusion, mixed with the bituminous coal, as 2~5 weight%(S30). |
