The granulation of iron ore is an important process in the iron ore sintering. It strongly affects the permeability of sinter bed and then affects the productivity and properties of produced sinter such as strength and reducibility. The granulation ability of limonite ores was poor; they should be used with high granulation ability iron ores to ...

The iron and steel industry has made an important contribution to China's economic development, and sinter accounts for 7080% of the blast furnace feed charge. However, the average grade of domestic iron ore is low, and imported iron ore is easily affected by transportation and price. The intelligent ore blending model with an intelligent algorithm as the core is studied.

The target basicity of iron ore sinter is set by blast furnace slag composition requirements, and therefore varies with the proportion of acid burden such as lump iron ore and pellets. Increasing the lump proportion of the burden will increase the target sinter basicity. The mineralogy of sinter produced with a range of basicity between and was analysed using optical point counting ...
