Pelletization is one of useful processes for the agglomeration of iron ore or concentrates. However, manganese ore fines are mainly agglomerated by sintering due to its high combined water which adversely affects the roasting performance of pellets. In this work, high pressure roll grinding (HPRG) process and optimization of temperature …
The present work proposes a novel process to sinter porous iron ore (porosity ~23–24%) with enhanced productivity and quality. The iron ore is pre-processed in the presence of calcined lime for the temporary closure of pores, which further prevents water absorption during the granulation process in drum in the presence of water. The …
Abstract. Manganese ores differ extensively in their mineralogical and bulk chemical composition. Consequently these ores follow different mineralogical …
In 1970, the first sintering machine for fine manganese ore (18m2) was built and put into operation in Xiangtan Manganese Mine. In 1972, two 24m2 sintering machines were built in Xinyu Iron and ...
