“…The micropore volume and total pore volume are in line with the work of ElOuahabi et al [25] in which the pore volume and total pore volume of some selected clay materials were recorded as 0.05 cm 3 /g and 0.015 cm 3 /g respectively. Surface area of 234m 2 /g as compared with the works of ElOuahabi et al [25] shows that BSG is a good candidate for Fe (III) ion removal. From the results of Table 2, it was observed that the mass of Iron (III) oxide (Fe2O3) present in BSG is low (1.243g/kg).…”

This work investigated the performance of locally available brewer's spent grain (BSG) as an adsorbent for the removal of Fe (III) from aqueous solution. The brewer's spent grain (BSG) was collected, processed and characterized using scanning electron microscope (SEM) and X-ray fluorescence (XRF) to assess its potential for the removal of Fe (III). Thereafter, batch adsorption technique was employed to evaluate the effects of adsorption variables such as pH, initial metal ion concentration, adsorbent dosage and contact time on the sorption efficiency of BSG. The maximum adsorption time was fixed at 120minutes with a stirring speed of 100rpm. Experimental data obtained were then analyzed using selected isotherms and kinetic models such as Langmuir isotherm, Freundlich isotherm, Pseudo-First order and Pseudo-Second order kinetic models. SEM result revealed the presence of microporous structure within the surface of BSG thus making it a good candidate for metal ion removal. Based on the linear coefficient of determination (r 2), it was observed that the experimental data fitted well with the Langmuir isotherm model (r 2 = 0.9940 for raw BSG and 0.9946 for the treated BSG). In addition, the reaction mechanism that accompanies the adsorption of Fe (III) unto BSG was best described by the pseudo-second order kinetic model (r 2 = 0.9823 for raw BSG and 0.981 for the treated BSG). Finally, maximum adsorption efficiencies of 66% and 77% were obtained for both the raw and treated BSG for optimum adsorption time of 120 minutes, pH 8.0 and adsorbent dose of 1.0g/50ml solution.

“…Due to the growing concern about the economy and the recovery of the basic ceramic industry in Morocco, it is becoming imperative and crucial to look for new raw materials containing magnesium. However, the main focus of discussion only to use three essential minerals forming the rocks: Magnesite, dolomite and lizardite situated in the Rif of Morocco, and which has other secondary materials: perlite, halloysite, diatomite, bentonite and red clays [24][25].…”

Lizardite rich peridotite has never been used to prepare ceramic specimens, especially in Morocco. For this raison, potential use of naturally abundant lazirditic material from the Rif domain (NW morocco), as a supply for ceramic industry, has been evaluated. The effects of lizardite addition to magnesite and dolomite mixtures on the thermomechanical properties of the calcined ceramics were also detailed. To achieve this target, natural lizardite, magnesite and dolomite samples were collected in ultrabasic Beni Bousra massif. Those raw samples were used for the synthesis of a forsterite-monticellite rich ceramics. Both raw and sintered samples were characterized by x-ray diffraction (XRD), scanning electron microscope (SEM) and fourier transform infrared (FTIR). Main physical and mechanical properties were assessed and correlated to their respective microstructural changes. The obtained results showed that both magnesite and dolomite were mainly composed of MgCO3 and CaCO3. In contrast, lizardite sample showed high amounts of silica, magnesia and iron oxide. Technological tests indicated that the prepared mixtures had increased flexural strengths. An increased amount of lizardite in the initial mixtures enhanced mechanical properties of the prepared ceramic specimens. The same data showed that lizardite has led to a decrease in linear shrinkage during calcination and subsequently, the production of ceramics with the required technological properties. Thus, the preparation of lizardite-based ceramics from the raw material deposits of the Rif area, Morocco, is technically feasible, economically justifiable and socially desirable due to the contribution to the economic growth of the raw materials sector, especially ceramic industry.

“…The literature reports that small amount of coloring oxides such as Fe 2 O 3 and TiO 2 less than 0.9 % may be accepted for porcelain wares production. Hematite promotes glassy phase formation and at the same time may affect glassy phase formation due to its reduction to FeO 4 at higher sintering temperature [12,13]. When the porcelain samples were fired up to 1300 o C, high vitrification and densification of the porcelains was observed at 1250 o C, however at the sintering temperature greater than 1250 o C porcelains became more porous and did not maintain their regular shapes and started to melt as shown in Figure 2.…”

The present work has evaluated Kalalani vermiculite as a potential raw material for the production of high strength porcelain insulators. Three porcelain compositions were prepared to contain 0, 20 and 30 wt% of Kalalani vermiculite. Porcelain samples were fabricated using a semi-drying method. The chemical, mineralogical phases and microstructural characterization of the raw materials were carried out using XRF, XRD, and SEM techniques, respectively. Water absorption, bulk density, dielectric and bending strengths were performed on porcelain samples fired up to 1300 o C. However, at the sintering temperature of 1250 o C, the porcelain sample with 20 wt% of Kalalani vermiculite gave the dielectric strength of 61.3 kV/mm, bending strength of 30.54 MPa, bulk density of 2.21 g/cm 3 and low water absorption value of 0.21 % which is the prerequisite properties for high strength porcelain insulators. It was therefore concluded that Kalalani vermiculite has the potential to be used for the production of high strength porcelain insulators.
