Iron ore grindability improvement by microwave pre-treatment

The high-grade iron ore fines contain 64% Fe, 2.25% LOI, and Blaine number 2975 cm²/g, whereas iron ore slimes contain 52.45% Fe, 5.60% LOI, and Blaine number 7046 cm²/g. Pellets were producedprojection area of iron ore before and after sintering [9–11]. Some scholars also evaluated the degree of reaction between the original melt and iron ore by placing 15 wt.% CaO and Fe 2O 3 chemical reagent on the pressed iron ore sheet [12–14].

Investigation on Iron Ore Grinding based on Particle Size Distribution

The feed samples of X, Y, and Z iron ores were ground in the BBM (ball mill refers to a BBM of size 300 mm × 300 mm with smooth liners) to identify the PSD, BWI, and RT of each ore. Grinding experiments were conducted according to Bond’s standard test procedure [].For each iron ore sample, the RT taken to produce 250% circulating tertiary crushing application. • More efficient grinding than Ball Mill. • Utilising more of the capability of the.
