“…[23][24][25] Some of the studies address the use of serpentinite tailings from mineral processing. 22,23 The use of serpentinites in ceramics and civil construction ( Figure 7) is mainly due to its mechanical properties and also to its dark green color. Serpentinite has also been used as a thermal and electrical insulator in industrial applications.…”

Serpentine is a versatile mineral family rich in Mg silicate with several polymorphic phases, mainly antigorite and lizardite, all of them with similar chemical composition (Mg 3 Si 2 O 5 (OH) 4 ). Their structures are generally composed of octahedral layers rich in Mg[MgO 2 (OH) 4 ] 6− , attached to a tetrahedral silicate [Si 2 O 5 ] 2− sheet. The unique physicochemical properties of serpentinites and the existence of large reserves in Brazil create new important opportunities for research and technological applications. In this work, serpentinites structures and properties are reviewed, as well as its occurrence and literature describing its applications in construction/ceramics, agriculture, as a silica source, in steel production, as an additive/filler in polymers, in the production of composites, adsorption of cations and organics contaminants, CO 2 capture and catalysis. The presence of harmful chrysotile associated with serpentinites, some of its properties and uses are also described.

“…The aim of this study is to evaluate the main chemical and mineralogical characteristics of these waste rocks (peridotites). The study also aims to investigate the possibility of enriching these waste-(as they are currently considered) or by-products with the application of a convenient magnetic separation process [8,9], alongside the investigation of the effect of thermal treatment and with the addition of different metal oxides (CaO, Al 2 O 3 , SiO 2 , MgO, Cr 2 O 3 ), [1][2][3][4]10]. The aim is to initially develop a laboratory-based-but later a potentially industry-applicable-technology, regarding the conversion of a waste material into a useful product with commercial added value, i.e., applying the principles of a circular economy to mining operations.…”
