Reaction Behavior of Phosphorus in Coal-Based Reduction of an Oolitic Hematite Ore and Pre-Dephosphorization of Reduced Iron
Coal-based reduction followed by magnetic separation is an effective way to recover iron from high phosphorus-containing oolitic hematite ore. Given that high quantities of dephosphorization agent are needed to obtain low phosphorus reduced iron, a novel approach is proposed by the authors. Without prior phosphorus removal, the phosphorus was enriched in the reduced iron during a reduction proc...
متن کاملRecovery of Manganese and Phosphorus from Dephosphorization Slag with Wet Magnetic Separation
The dephosphorization slag has a great potential as the secondary resources of manganese and phosphorus, while quite a large amount of slag is landfilled and simply reused such as cement. The objective of this study is to investigate the recovery of manganese and phosphorus by wet magnetic separation technique. The hot metal pretreatment slag (dephosphorization slag) generally contains a Ca3P2O...
متن کاملThe Effect on Activated Sludge of Chemical Coagulants Applied in Synchronization Dephosphorization
Combined with the practical experience of wastewater treatment plant, the chemical coagulants have inhibition effects on microorganism activity, with the influence degree of PAC (polyaluminium chloride) > AlCl3> Fe2(SO4)3. In synchronization dephosphorization, the inhibition rates of PAC in 10 ppm and 20 ppm are 11.9% and 33% respectively; while the inhibition rates of AlCl3 and Fe2(SO4)3 in 20...
متن کاملDry Sintered Metal Coating of Halloysite Nanotubes
Halloysite nanotubes (HNTs) are a naturally-occurring aluminosilicate whose dimensions measure microns in length and tens of nanometers in diameter. Bonding defects between the alumina and silica lead to net negative and positive charges on the exterior and interior lumen, respectively. HNTs have been shown to enhance the material properties of polymer matrices and enable the sustained release ...
متن کاملHot Deformation Behavior of Haynes 25 by the Hot Tensile Test
In the present work, hot tensile behavior of Haynes 25 Co-base alloy was investigated in the temperature range of 950-1200 ˚C and 0.1 s-1. Thermodynamic calculations showed that M23C6 and M6C carbides were stable below 1000 ˚C and above 1050 ˚C, respectively. Stress-strain curves also indicated an unusual trend of strain fracture. It was observed that with increasing temperature from 950 to 105...
