“…The removal of metal ions from wastewater using brucite can be carried out by the parallel processes of ion exchange adsorption and chemisorption: adsorption on the surface of the mineral with the formation of bulk aqua-and hydrocomplexes with OH groups, and the replacement of Mg 2+ ions by ions of the sorbed metal (Calugaru et al 2016;Korolev et al 2016;Orekhova et al 2021). At the same time, the sorption of strontium occurs with the formation of strontianite (SrCO 3 ) on the brucite surface (Bochkarev and Pushkaryova 2009).…”

“…It is known that the efficiency of sorption treatment with brucite is directly proportional to the pH; therefore, the decreased efficiency in solutions at initial pH values of 2 and 4 is explained by the established optimal solution pH range of 7.5-9 (Bochkarev and Pushkaryova 2009). At the same time, once dissolved, brucite is capable of alkalinizing water, which is why it is used to neutralize acidic mine waters (Korolev et al 2016).…”

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.

“…It is used as a flocculant for waste water purification from organic compounds, and for neutralizing waste acids in technical processes [2]. It was shown in [3,4] that the natural mineral brucite (consisting mainly of Mg(OH) 2 ) and the synthetic brucite-structured magnesium hydroxide with partial isomorphic substitution exhibit sorption properties with respect to heavy metal ions [5]. Magnesium hydroxide is also used as a filler in pharmaceutical preparations, and as an antacid to neutralize the acidic environment of the stomach [6].…”

The effect of nickel content in Mg 1−x Ni x (OH) 2 nanoparticles produced by reverse co-precipitation on their structural characteristics, morphology and size parameters of crystallites and particles has been studied. The plate-shaped nanoparticles were shown to be predominantly single crystals. It has been determined that when the nickel content x in the hydroxide solid solution is not less than 0.4, the particle size sharply decreases and the number of stacking faults increases. The dependence of the dehydration temperature of Mg 1−x Ni x (OH) 2 nanoparticles on the nickel content has been revealed. KEYWORDS magnesium hydroxide, nickel hydroxide, layered double hydroxide, nanoparticles.

The problem of an increased level of fire danger in the residential sector among private houses and at the administrative and public buildings can be solved by reducing the flammability of both the entire structure and individual components of the building structure. In this paper, the possibility of using a magnesium-containing mineral to protect the chimneys of the sandwich pipe structure from excessive heating and to increase the level of fire safety during the organization of furnace heating is considered. Based on the results of studies using, a positive conclusion was made about the prospects of using the studied material as a filler with or sandwich pipes. The reduction of overheating of the roof elements in this case will occur due to the individual physico-chemical properties of the filler. This will reduce the number of chemical gorenje inhibitors that have a negative impact on the environment and people, to protect the wooden elements of the roof structure. Ill. 5. Ref. 18. Tab. 1.
