“…The purification of low-grade talc ores represents an area of great interest, owing to the limitations, economics and environmental impacts of current technologies, and the wide array of possible accessory minerals associated with talc and their distinct intrinsic reactivities. Examples of such technologies include flotation, wet attrition, magnetic separation, and acid leaching (Table 1; Piga and Marruzzo, 1992;Ahmed et al, 2007;Hojamberdiev et al, 2010;Orosco et al, 2011;Dumas et al, 2015;Barani and Aghazadeh, 2018;Katircioglu-Bayel, D., 2020).…”

“…In a former paper, we suggested a firing temperature of up to 1200 °C, but the use of talc (melting of samples) did not allow performing heat treatments above 1100 °C. On the other hand, talc is a magnesium hydrosilicate with the theoretical formula 3MgO•4SiO 2 •H 2 O, corresponding to 63.35 mass% SiO 2 , 31.90 mass% MgO, and 4.75 mass% of chemically bound water (hydroxide) [20]. In contrast, other minerals can be associated with talc, such as, chlorites, mica, actinolite, feldspars, rutile, pyrrhotite, carbonates, pyrite, magnetite, and hematite [12].…”

In recent decades, talc and kaolinite have been widely used as raw materials for the ceramic industry. In this study, the final characteristics of kaolinitic clay mixed with 6 mass% of magnesite obtained in our previous work were compared with those obtained with mixtures of kaolin (kaolin BIP) and talc (as the source of magnesium oxide). However, different amounts of talc in the kaolin powder were studied, namely 10, 30, and 50 mass% of added talc (with respect to kaolin + talc). The tape casting process was used during this work in order to manufacture the green tapes in an aqueous system with 0.2 mass% of dispersant. Subsequently, the green tapes were heated to 1000 and 1100 °C with a dwelling time of 12 min. The green and sintering tapes were characterized using the following techniques: DTA/TG, X-ray diffraction, porosity, and flexural strength analyses. The results obtained from our previous work indicate that the specimen with 6 mass% of MgCO3 sintered at 1200 °C for 3 h exhibited the best performances, with high flexural strength and weak porosity value—117 MPa and 27%—respectively. As results from this study, the optimal mechanical and thermal properties of sintering tapes were obtained for the specimen with 10 mass% of added talc sintered at 1100 °C. Indeed, this specimen exhibited 50 MPa and 43% of stress to rupture and apparent porosity, respectively.
