The boosting of microwave roasting technology on the desulfurization of phosphate rock

Recent Advances in Elimination of SO2 and NOx from Flue Gas Employing Phosphorus Sludge and Phosphate Rock

“…The composition of phosphate rocks in different regions also varies due to geographical environmental factors, as shown in Table . The research by He et al shows that the specific surface area, pore volume, and average pore size of phosphate rock from China are 3.78 m 2 /g, 0.011 cm 3 /g, and 11.27 nm, respectively . Özer et al investigated the phosphate rock in Mazidagı (Turkey) and found that the specific surface area, pore volume, and density are 15.68 m 2 /g, 0.0867 cm 3 /g, and 1.93 g/cm, respectively …”

“…Therefore, improving mass transfer efficiency is the key to efficient desulfurization. To improve the sustainability of efficient desulfurization of phosphate rock, He et al 36 used microwaves to heat the phosphate rock. Microwave heating of phosphate rock can cause structural damage, giving rise to an ascent of 40.25% in the specific surface area of phosphate rock.…”
