“…The antagonistic effects of magnesium and aluminum and resulting reduction of Al-induced oxidative stress in plants have been reported in many studies [ 83 , 84 , 85 ]. Notably, brucite can effectively remove metal ions, arsenic, and organic pollution [ 86 , 87 , 88 , 89 ]. The sorption properties of opoka with respect to heavy metals, phosphates, and other substances have been studied as well [ 90 , 91 ].…”

This paper presents an assessment of the effect of various reagents on the qualitative indicators of anti-deflationary single-species sowing phytocenosis on enrichment waste from rare earth ores. It has been established that tailings of loparite ores are not suitable for biological reclamation due to low values of hygroscopic moisture (0.54–2.85%) and clay particles (17.6 ± 0.6%) and high content of bioavailable forms of aluminum (504 ± 14 mg/kg). Seeds of red fescue (Festuca rubra L.) were grown on the tailings of loparite ore enrichment with the addition of opoka (O), brucite (B), and vermiculite (V). The quality of the seed cenosis was assessed by the dry biomass of the above-ground parts of the plants and the plant height. A positive effect (one-way ANOVA followed by Tukey’s HSD test (p < 0.05 and p < 0.01)) of the considered combinations of reagents on the growth of above-ground biomass from 31.5% (V) to 70.3 (V + O), 82.4% (V + B), and 81.8% (V + O+B) and on plant height from 53.8% (V) up to 78.6 (V + O), 83.8% (V + B), and 75.4% (V + O+B) was revealed. The use of a combination of V + O and V + B reagents made it possible to significantly reduce the content of Al (by 19.0% and 52.8%), Sr (by 16.5% and 12.9%), La (by 65.2% and 40.6%), and Ce (by 66.8% and 41.9%) in the aerial part of the sowing phytocenosis compared to control. The results obtained here can become the basis for development of a combined sorption technology for the reclamation of technogenically disturbed lands.

“…The conducted researches on arsenium sorption recovery using modified forms of brucite showed that [22]: 1) brucite effectively removes arsenium from aqueous media in the form of hardly soluble compounds suited for disposal (ПРMg 3 (AsO 4 ) 2 -2.1·10 -20 );…”

The article presents the theoretical and experimental research findings aimed to create a basis for the development of innovative integrated processing technologies for complex ore and mine waste. It is found that introduction of nonmechanical energy treatment by an accelerated electron beam in the ore dressing circuits increases rebellious mineral processing data. The features of a flotation unit process are analyzed from the viewpoint of improvement of collecting and selecting abilities of a reagent and relationship between these abilities and molecular structure of the reagent. The authors define flotation activity of reagents and offer a flotation contact formation criterion. It is proved to be effective and promising to use magnesium-and manganese-bearing minerals for sorption purification of mine effluents in order to reduce metal loss in the wastewater discharge and to minimize damage of natural water bodies.

“…The main functional groups providing binding sites for sulfate uptake onto the biosorbent are the amine and quaternary ammonium groups. Brucite can remove metal ions, arsenic, and organic pollution effectively (Akinwekomi et al 2016;Bochkarev and Pushkaryova 2009;Bochkarev et al 2010Bochkarev et al , 2014Makarov et al 2009;Masliy et al 2012;Orekhova et al 2021;Pushkaryova 1999;Sulaiman et al 2018). For both, the removal mechanism is based on the principle of ion exchange.…”

Removal of Sulfate and Metals from Wastewater of a Mining Enterprise by a Dual Sorbent System: A Case Study

This paper presents the results of wastewater treatment at a mining enterprise developing a complex ore deposit in the Murmansk region, Russia. The main pollutants are sulfate, manganese, and strontium. For this complex wastewater treatment, a two-stage scheme was proposed and tested using two sorbents (at a pH of 6): an aminated peat biosorbent to remove sulfate and a commercial sorbent based on the mineral brucite to remove metals. Optimal conditions were established for purifying the wastewater of sulfate and manganese and strontium ions to the level of maximum available concentrations in water bodies for fishery purposes.
