In this paper the technology of dry and wet recovery of electrode materials which was widely used in the market was introduced According to the investigation and analysis of the production cost and the income data of the recovery process the economic profit obtained was calculated and analyzed
Therefore the wet extraction process is challenging to apply to other SC When the composition of SC changes the recovery process parameters need to change which seriously restricts the popularization and application of the wet recovery process In recent years it has been an emerging harmless treatment method to incorporate the SC into the
The maximum REE recovery of 62% in the acid leaching process with sulfuric acid was obtained for La in the condition of 12 M acid concentration leaching time of 4 h process temperature of 25°C
Three cases of coke production process based on the quenching mode and waste heat recovery are researched through thermodynamic techno economic and CO 2 emissions analysis Case CWQ represents the process with coke wet quenching CWQ Case CDQ represents the process with coke dry quenching CDQ and Case WHR represents the
Several methods have been used for the recovery and elimination of uranium from wet process phosphoric acid including ion exchange [12][13][14] membrane [15] solvent extraction [7 16
Oxalic acid was used as a stripping agent to recover the associated metal resource Fe from wet process phosphoric acid by solvent extraction and ferrous oxalate was prepared by the photochemical reaction of Fe III oxalate complexes
The wet sulfuric acid process WSA process is a gas desulfurization process After Danish company Haldor Topsoe introduced this technology in 1987 it has been recognized as a process for recovering sulfur from various process gases in the form of commercial quality sulfuric acid H 2 SO 4 with the simultaneous production of high pressure WSA process can be
The amount of energy that is consumed is a crucial factor in wastewater treatment plants Mallu et al 2021 Sean et al 2020 The distillation column plays a crucial role in the chemical separation process and consumes a disproportionately large amount of the plant s overall energy supply; hence any efforts made to reduce its energy footprint are highly
The importance of phosphorus Phosphorus is a primary element in nature and an indispensable element in the process of life activities Phosphorus is ubiquitous in all organisms and accounts for about 2 4% of the dry weight of most cells [] Phosphorus exists in the basic genetic structure of DNA and RNA and plays an irreplaceable role in the inheritance and reproduction of all living
The cyanidation process was invented in 1887 when the gold recovery started to have some problems due to the lack of good technology Basically the process is supported by two facts gold is soluble in dilute solutions of cyanide and second the pregnant solution can be processed successfully by using zinc powder or activated carbon and
Wet recovery and regeneration process of LiFePO4 500 600 ℃3 5 h 85 ℃ 。 m ∶m H2O =1∶3 。
A novel process of lithium recovery as lithium ion sieve from the effluent obtained in the process of spent lithium ion batteries recycling is developed Through a two stage precipitation process using Na 2 CO 3 and Na 3 PO 4 as precipitants lithium is recovered as raw Li 2 CO 3 and pure Li 3 PO 4 the best reaction condition both the amounts
To enhance gasification efficiency during the concentration process of WPA a great deal of work has been conducted In long term experiments researchers have demonstrated that active silicon reagents in amorphous states possess the capability to facilitate the gasification of liquid H 2 SiF 6 Ning 2010 Consequently solid mineral reagents
The potential of a new wet chemical process for phosphorus and aluminium recovery from sewage sludge ash by sequential elution with acidic and alkaline solutions has been investigated SESAL Phos sequential elution of sewage sludge ash for aluminium and phosphorus recovery Its most innovative asp
In this paper a process route for the recovery and resynthesis of spent ternary lithium battery cathode materials was proposed combined with the recovery process of hydrometallurgy and pyrometallurgy The results showed that NCM622 could be completely decomposed into a mixture of Co Ni MnO and Li2CO3 by carbothermal
Acid leaching is the main process for wet recovery Wet acid leaching usually includes sulfuric acid hydrochloric acid nitric acid and phosphoric acid The roasting leaching method is a relatively mature recovery process of waste SCR catalyst with simple operation and high product purity During the roasting process vanadium tungsten
In the process of flue gas purification for coal fired boiler wet flue gas desulfurization WFGD is one of the most important sections [1] [2] In a WFGD system the injection of a large amount of sorbent solution can remove SO 2 effectively while causing the gas temperature to decrease and the flue gas to be saturated with water Generally the
The wet process is low cost but produces a large amount of PG the characteristics of which are mainly determined by the composition and quality of the phosphate ore [39] Recovery of uranium from wet process phosphoric acid Ind Eng Chem Process Des Dev 11 1 1972 pp 122 128
The most used P recovery technologies are based on the precipitation of phosphoric minerals from liquid wastes through the formation of struvite hydroxyapatites or calcium phosphates [7] High quality phosphoric minerals can be obtained from this process with recovery rates of 99 100% and can be applied directly in agriculture [9 10] For instance
The recovery and reuse of highly alkaline caustic in the textile sector are not well covered in the literature despite the fact that many researchers have examined color removal from textile wastewater The mercerization process consumes the most caustic solution; hence it is the primary subject of most writing on caustic recovery
The recovery of fluorine and iodine in the production and concentration of wet process phosphoric acid WPA can not only reduce environmental pollution but also increase the added value of
Foam has been implemented in the field for a wide range of applications such as enhanced oil recovery EOR aquifer remediation and acid diversion among others [1] [2] [3] [4] Foam transport in porous media is a dynamic process of lamellae generation and coalescence which ultimately determines the foam microstructure and hence the gas mobility in porous
Tertiary recovery is the process in which different combinations of chemicals or thermal energy or microbes are infused into the reservoir which alters the reservoir rock and fluid properties relative permeability capillary pressure within the porous medium interfacial tension and wettability to recover crude oil and helps in additional
