The properties of fibrosis bentonite and its performance in iron ore pelletizing were studied. The results show that the dehydration rate of fibrosis bentonite......
indicate water carrying ability and foam viscosity, respectively. The performance of four frothers in a two-phase (solution-air) system was tested and batch flotation tests on a copper ore were carried...; copper ore 1 Introduction Froth flotation is a separation process widely used in mining industry and froth phase is of crucial importance since it can affect both recovery and grade through selective......
of lime slurry and iron ore fines helped to improve the granulation effect, and optimize the carbon distribution in granules. When the mass ratio of coke breeze, quick lime, water and iron ore fines was 2:1:1:1, the average NOx emission concentration was decreased from 220 mg/m3 to 166 mg/m3, and the conversion ratio of fuel-N was reduced from 54.2% to 40.9%. Key words: iron ore sintering......
