Near complete conversion of calcium silicate minerals such as wollastonite (CaSiO 3) and magnesium silicate minerals such as olivine ((Mg,Fe) 2 SiO 4) were achieved on reacting for 3–6 h 22–24. In contrast, the reactivities of alumino-silicate bearing minerals and rocks do not exceed 50% at comparable reaction conditions 22.

Magnesium silicate hydrate (M─ S─ H) cement has many excellent properties, but its resistance to corrosion by SO 4 2 − and Cl − has not been investigated. In this study, M─ S─ H cement was prepared from light burned magnesia powder obtained from magnesite tailings, and its erosion resistance for SO 4 2 − and Cl − was investigated. X-ray diffraction (XRD) and flight …

Some rocks in nature contain a large number of calcium–magnesium silicate minerals, such as calcium-rich wollastonite (CaSiO 3), magnesium- and iron-rich olivine (Mg 2 SiO 4 and Fe 2 SiO 4), serpentine (Mg 3 Si 2 O 5 (OH) 4), and talc (Mg 3 Si 4 O 10 (OH) 2).

The mineral talc is a hydrous magnesium silicate. A massive talcose rock is called steatite, and an impure massive variety is known as soapstone. Talc is used commercially because of its fragrance retention, luster, purity, softness, and whiteness. Other commercially important properties of talc are its chemical inertness, high dielectric ...

In order to explore a wider range and lower cost of raw materials for the preparation of magnesium silicate hydrate (M-S-H), an acid-leaching method was employed to extract …

Magnesium silicates includes various types, such as talc-type [15,16], chrysotile-type [17], and sepiolite-type [18], etc., in which talc-type magnesium silicate has been widely investigated for adsorption of pollutants due to its high surface area and the presence of active silanol groups on the surface.

The use of alternative sources of nutrients, such as mining co-products, is an ancient practice that has been increasingly applied in recent years to reduce production costs and increase the residual effect of soil fertilisation (Toscani and Campos, 2017).Silicate rocks and mining co-products contribute to medium and long-term increases in soil fertility according to …

Silicate minerals rich in Mg 2+, Ca 2+ and Fe 2+ are the main resource base for mineralisation owing to their geographic distribution, reactivity and enrichment with Mg 2+, Ca 2+ and Fe 2+ …

Talc is a hydrous magnesium silicate mineral with a chemical composition of Mg 3 Si 4 O 10 (OH) 2. Although the composition of talc usually stays close to this generalized formula, some …

The formation of magnesium silicate hydrates (M-S-H) with MgO to SiO 2 ratios from 0.7 to 1.6 has been studied at 20, 50 and 70 °C. TGA and XRD data reveal that initially brucite and M-S-H are formed while amorphous silica is still present as indicated by FT-IR and 29 Si MAS NMR experiments. In this first step M-S-H with Mg/Si ∼1 with pH values ∼9.4 is …
