One emerging area where Utilization of waste sodium sulfate from battery chemical production
The market capacity of sodium sulfate is limited and its economics is poor. Therefore, it is important to develop a new process to utilize sodium sulfate economically. Release to the environment of this substance can occur from industrial use: in processing aids at industrial sites, as processing aid, formulation in materials, as an intermediate step in further manufacturing of another substance (use of intermediates), in the production of articles and formulation of mixtures.

Description. Sodium sulfate anhydrous is used primarily for drying non-aqueous solvents by removing traces of water. It is used as a fining agent for molten glass, levelling agent in textile processing, and filler in detergents. It is also used in Kraft process for paper pulping, defrosting windows, manufacture of starch, glass, and soap.The present invention provides a kind of methods of sodium chloride processing sodium sulphate ammonium sulfate mixture.Its process characteristic is directly heated after mixing sodium chloride and mixed waste, removes the ammonium ion in mixture, and side product sodium chloride.This method small investment, simple for process, energy consumption CN108203106A A kind of method that sodium sulphate

Sodium Sulfate: Handbook of Deposits, Processing, Properties, and Use will be the authoritative and up-to-date distillation of all that is known about naturally occurring sodium sulfate, detailed information on formation, worldwide deposits, processing technologies, and usage over time. Garrett provides a comprehensive overview of sodium sulfate from Lithium carbonate is an important chemical raw material that is widely used in many contexts. The preparation of lithium carbonate by acid roasting is limited due to the large amounts of low-value sodium sulfate waste salts that result. In this research, bipolar membrane electrodialysis (BMED) technology was developed to treat waste sodium Recovery of Acid and Base from Sodium Sulfate Containing
Abstract Current efficiency in the sodium chlorate process is a key issue in the evaluation of the power consumption. A pilot cell unit for executing the sodium chlorate process was constructed to study the current efficiency of the anode and cathode separately. The effects of sodium dichromate and sodium sulphate concentrations and Recovering by-product sodium sulfate allows the recycling of the mother liquor, saturated in boric acid, to the beginning of the process thus minimizing the liquid discharge. Sodium sulfate is also valuable as it is used, for example, in dyeing and stamping of fabrics (textile industry), and eliminating calcium from brines in order to obtainSodium sulfate recovery from boric acid liquors ScienceDirect
Sodium Sulfate (Na2SO4) -Sodium sulfate is the sodium salt of sulfuric acid. Anhydrous sodium sulfate is a white crystalline solid also known as the mineral thenardite. While the decahydrate sodium sulfate has been known as Glauber’s salt or mirabilis. To learn more about the Structure, Properties, Preparations, Uses and FAQs of Sodium sulphate, Visit Similar results were found by Li et al. (2015) for molybdenite as they reported that addition of sodium sulphate, potassium sulphate or calcium sulphate all depressed molybdenite flotation in alkaline pH conditions. However, it was reported that sodium sulphate (0–10 −2 M) had no or little effect on chalcopyrite flotation (Ikumapayi Understanding the effect of sulphate in mining-process
Finnish Minerals Group’s research and development on the processing of sodium sulphate has been a long-term effort. The company launched the monitoring and evaluation of developing processing technologies in 2015. In the years that followed, different technologies were researched, and piloted, and technical-economical In this process, sodium sulfate values from the spin bath are recovered via an evaporative crystallization step. The mother liquor from the evaporation step is returned back to the spin bath. Solid sulfate from the crystallizer, typically Glauber salt, is then dissolved in water and purified to remove metals such as Ca, Mg, and Zn.Sodium Sulfate an overview ScienceDirect Topics
