and Bedding Section,Tata Steel Ltd.摘 要:The Linz-Donawitz(LD) steelmaking process produces LD slag at a rate of about 125 kg/t. After metallic scrap recovery...Phosphorus partitioning and recovery of low-phosphorus iron-rich compounds through physical separation of Linz-Donawitz slagDilip Makhija1,Rajendra Kumar Rath2,Kaushik Chakravarty1,Abhay Shankar......
Dynamic test on waste heat recovery system with organic Rankine cycleWANG Zhi-qi(王志奇)1, 2, LIU Li-wen(刘力文)1, XIA Xiao-xia(夏小霞)1, ZHOU Nai-jun(周乃君)2(1. Institute of Mechanical Engineering, Xiang Tan... and monitoring of the organic Rankine cycle(ORC) system so to avoid the occurrence of unwanted conditions. A small scale waste heat recovery system with organic Rankine cycle was constructed and the dynamic......

. The partition coefficient, separation factor and recovery rate were used to evaluate the effects of MMT, and the selection factor was primarily proposed to define the selectivity of mine gas hydrate... mechanism explores the effect of MMT enrichment methane from mine gas. Key words: mine gas; hydrate; montmorillonite; separation effect; partition coefficient; separation factor; recovery rate; selection......
29 July 2020 Abstract: A novel process of composite roasting with CaO/MgO and subsequent acid leaching was proposed to improve the recovery rate of vanadium from Linz–Donawiz (LD) converter vanadium... and a vanadium recovery rate of approximately 90% can be achieved [13], problems such as large-scale emission of corrosive gases (HCl, Cl2, SO2, and SO3) [14], easy slag fusion and agglomeration......
solution achieves high extraction rate of V2O5 or Na2Cr2O7·2H2O. All results suggest that high pH and NaHCO3 favors the recovery of vanadate and chromate from CVR. Furthermore, the Na2Cr2O7·2H2O... J. Cent. South Univ. (2018) 25: 2349-2359 DOI: https://doi.org/10.1007/s11771-018-3919-0 Safe utilization of chromium-bearing vanadate residue by recovery of vanadium and chromium based on calcium......
recovery rate of above 52% is lost in the tailings (Tailing 1+2). On the other hand, OAF process using 7.1 kg/t transformer oil as collector and bridging reagent can obtain a superior molybdenum concentrate... surface, which will render the mineral particles more hydrophobic and a high recovery rate of molybdenite will thus be achieved [30]. At the same time, the flotation of pyrite may also be intensified......
permeability, well penetration (especially fracture permeability), vertical-to-horizontal permeability ratio, aquifer size and gas production rate have considerable effect on water coning... in which the breakthrough of water coning is delayed.Key words:water coning; fractured gas reservoir; water cut; recovery factor......
recovery process with joint production of spherical calcium carbonate was designed. This process is technically viable and considerable in economic benefit. Key words: sintering dust; potassium salt; recovery experiment; spherical CaCO3 1 Introduction Potassium chloride is one of the most important potassium fertilizers, and also is the major raw material of non-chloride potassium fertilizers......
