Sintering Pot Test of Manganese Ore with Addition of Manganese
For sintering of manganese ore with added manganese furnace dust in sinter pot A (150 300mm) in test series 1 and 2, both sinter yield and zinc removal rate consistently decreased with increasing sintering time, and the overall zinc removal rate was low, in the range of 115–23% depending on the sintering time It increased to 17–32% when
Phase compositions of manganese ores and their change in the process
The focus of this paper is on the phase composition of the ore in the temperature range 800–1200 °C when the ore is exposed to the CO or H 2 gas; under these conditions manganese oxides are reduced only to MnO The paper also studies the phases formed in this temperature range in air, as these conditions are relevant to the sintering
Reduction behavior of medium grade manganese ore from Karangnunggal
An increase of the keeping time up to 45 minutes during the sintering process leads to an increase of the MnO concentration, while at 90 minutes, the concentration decreases The analysis based on the interpretation of both XRD patterns and FTIR spectrum allows one to explain the blockage in the particle surface of the ore by an
Influence of Al2O3induced MnO2–SiO2 smelting on
Melting of MnSiO 3 and Mn 2 SiO 4 in the liquid phase at temperatures above 1250 °C is crucial for the consolidation of lowAl manganese ore This study examines the influence of Al 2 O 3 content on the sintering consolidation behavior of manganese ore fines, particularly the phase and micromorphological changes in silicate
