“…The existence of Al and Si elements causes the deviation of the band from 407 cm −1 verified in the standard pyrite FTIR spectrum to 474 cm −1 in the pyrite waste. 32,33 The FTIR spectra also confirm the existence of muscovite, quartz, and pyrite in pyrite waste. Furthermore, compared with fresh pyrite waste, there is no new absorption peaks appearing in the FTIR spectra of pyrite waste after Xe-lamp irradiation and Fenton catalytic reaction, indicating the superior stability of pyrite waste.…”

“…The phenomenon is well consistent with previous studies which have discovered that increasing temperature enables expedite diffusion rate and mass transfer and is an efficient pathway to facilitate the removal of pollutants. 33,55,56 Therefore, making full utilization of the stored thermal energy originating from the photothermal effect is expected to be a better choice.…”

“…Moreover, the other prominent peaks (900-1250 cm -1 ) centered at around 1000 cm -1 are attributed to the stretching band of S-S bonds that shows the pyrite facets [28]. Lastly, the presence of the peaks centered around 600 cm -1 is denoted by the stretching vibration of a Fe-S bond [27], [29].…”

Heavy metals with high level of toxicity have negative impact on public health and the environment. In this research, Cu 2+ as a type of heavy metal was removed by using synthesized oxalate pyrite-alginate beads as an adsorbent. Pyrite is abundant in nature, and considered to be an omnipresent mineral. It is then functionalized with oxalate to improve its colloidal stability and increase its surface charge. The impacts of bead amount on Cu 2+ adsorption, initial Cu 2+ concentration, and recyclability test are three parameters that were studied in batch adsorption experiments. The highest removal of Cu 2+ can be achieved at 96.66% for 5 ppm Cu 2+ solution using 3 g of oxalate pyrite-alginate beads. The beads still can maintain the adsorption efficiency of 66.4% after 5 cycles of usage. The adsorption is best fitted in Freundlich isotherm. Hence, the composite shows high potential for heavy metals removal, especially Cu 2+ from aqueous environment.

“…Thus produced NPs were rinsed with a mixture of ethanol and deionized water (50/50) and dried at 105 • C [38]. The obtained NPs were studied for their ability to function as a catalyst for the activation of peroxymonosulfate (PMS) and peroxydisulfate (PDS) to oxidize tetracycline (TTC).…”

Mining waste can generate environment pollution including acid mine drainage (AMD). AMD is dangerous for its surroundings and can pollute surface and groundwater it is contacting with. Nanomaterials are advanced materials used in all fields of human activity and development. However, their production is still expensive and may pollute the environment due to the chemicals’ used and/or production of the energy needed for their synthesis. A smart solution could be use of mining waste and AMD to produce nanomaterials with properties similar to the properties of nanomaterials obtained from clean chemicals. Thus both waste will be valorised / decontaminated and useful and needed materials produced. This paper presents production of nanoparticles and nanomaterials from mining waste and AMD with emphasis on iron- and copper-based materials, as well as some applications of the obtained materials.
