“…The amount of water that a specific SAP can absorb depends on its chemical composition and morphology as well as the quality of absorbed water [ 41 ], particularly with respect to the presence of ionic salts. The recycled water used in mining plant operations generally contains a significant concentration of salts [ 42 ] that needs to be managed to maximize the polymeric absorption potential.…”

This review focusses on the use of recycled and virgin polymers in mineral and metallurgical processing, both high and ambient temperature processes, including novel applications. End of life applications of polymers as well as the utilisation of polymers during its life time in various applications are explored. The discussion includes applications in cleaner coal production, iron and steel production, iron ore palletisation, iron alloy manufacturing, manganese processing, E-wastes processing and carbon sequestration. The underlying principles of these applications are also explained. Advantages and disadvantages of using these polymers in terms of energy and emission reductions, reduction in non-renewables and dematerialisation are discussed. Influence of the polymers on controlling the evolution of micro and nanostructures in alloys and advanced materials is also considered.

Brown Coal Dewatering Using Poly (Acrylamide-Co-Potassium Acrylic) Based Super Absorbent Polymers

With the rising cost of energy and fuel oils, clean coal technologies will continue to play an important role during the transition to a clean energy future. Victorian brown coals have high oxygen and moisture contents and hence low calorific value. This paper presents an alternative non evaporative drying technology for high moisture brown coals based on osmotic dewatering. This involves contacting and mixing brown coal with anionic super absorbent polymers (SAP) which are highly crossed linked synthetic co-polymers based on a cross-linked copolymer of acryl amide and potassium acrylate. The paper focuses on evaluating the water absorption potential of SAP in contact with 61% moisture Loy Yang brown coal, under varying SAP dosages for different contact times and conditions. The amount of water present in Loy Yang coal was reduced by approximately 57% during four hours of SAP contact. The extent of SAP brown coal drying is directly proportional to the SAP/coal weight ratio. It is observed that moisture content of fine brown coal can readily be reduced from about 59% to 38% in four hours at a 20% SAP/coal ratio.

“…Acrylic acid (AA, K a = 5.6 × 10 −5 ) is a fairly cheap and common monomer [14], and 2-acrylamide-2-methyl propane sulfonic acid (AMPS) are anionic monomers consisting of a hydrophilic sulfonic acid group (K a = 2 × 10 −1 ) and a nonionic amide group [15], in which the non-ionic amide group gives the polymer better salt tolerance has attracted attention due to its stability, non-toxicity, and low cost [16]. The combination of both ionic hydrophilic groups (carboxyl groups, sulfonic acid groups, tertiary amine groups, etc) and nonionic hydrophilic groups (hydroxyl groups, ester groups, amide groups, etc) greatly improves the ability of salt tolerance and water absorption rate of the polymer [17]. Yeqiao Meng and Lin Ye have synthesized superabsorbent polymers based on starch and AA, AMPS has shown several advantages such as improved water absorption, swelling rate, high water retention, and salt tolerance [18,19], Elżbieta Czarnecka and co-workers showed that the -SO 3 H groups present in the AMPS groups of the potato starch-based superabsorbent polymer PVA/PS-g-P(AA-co-AM-co-AMPS) are responsible for the adsorption capacity higher water absorption than PVA/PS-g-P(AA-co-AM ) [20].…”

In this study, a novel superabsorbent polymer tapioca starch-g-poly(acrylic acid-2-acrylamido-2-methylpropane sulfonic acid)/ammonium polyphosphate (TS-g-AA-AMPS/APP) was synthesized based on the graft copolymerization of tapioca starch (TS) with acrylic acid (AA) and 2-acrylamido-2-methyl-1-propanesulfonic acid (AMPS) via free radical polymerization in aqueous solution with ammonium polyphosphate (APP) additive added for study. The synthesized superabsorbent polymer material was characterized by Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectroscopy (EDS), and thermogravimetric analysis (TGA). Research investigating the material synthesis conditions to absorbance in distilled water and 0.9 wt% NaCl solution has also been studied. Under optimal synthesis conditions, the absorbance in distilled water and 0.9 wt% NaCl solution were 416 g/g and 61 g/g, respectively, for the sample with 3 wt% APP content. The introduction of APP units has improved the absorption properties of the material such as the water retention capacity reaching 55.25% in 10 hours at 60 oC. TS-AA-AMPS/APP exhibits reversible swelling ability, with the swelling level not being reduced compared to the initial after 5 swelling-drying cycles at 60 oC, and water absorption reaches swelling equilibrium after about 270 minutes. Additionally, TGA thermogravimetric analysis results showed an improvement in the thermal stability of TS-AA-AMPS/APP compared to the pure polymer. These results show that the TS-AA-AMPS/APP polymer with excellent swelling properties, low production cost, and environmentally friendly has the potential for practical applications in agriculture, gardening, and water retention materials.
