Dephosphorization of manganese-containing oxide melts

Dephosphorization of Manganese Ore Raw Materials

“…This conclusion is supported by the experimental results on the phosphorus reduction by carbon monoxide for manganese-containing concentrates [4]. The degree of dephosphorization reached in that work does not exceed 80-90% and it is even lower in some cases.…”

“…As a result of blowing of carbon monoxide through the manganese-containing oxide melt, a dephosphorized product is obtained. If the starting manganese ore or concentrate contains 0.2-0.3% of P, then the resulting product will contain 0.01-0.03% of P [19]. processes does not exceed 65-70%.…”
