Maghnite-H+ xM” were prepared by a method similar to that described by Belbachir et al. raw maghnite (20 g) was crushed for 20 min using a Prolabo ceramic ball grinder. It was then dried by baking at 105 °C for 2 h. The maghnite was then weighed and placed in an Erlenmeyer flask together with distilled water (500 mL) and magnetically stirred maghnite/water mixture was combined with sulfuric acid until saturation was achieved. After 2 days at room temperature the mineral was washed with water until it became sulfate free and then dried at 150 °C. Sulfuric acid solutions of 0.05M, 0.10M, 0.15M, 0.20M, 0.25M, 0.30M and 0.35M concentration were used to prepare “Maghnite-H+0.05M”, “Maghnite-H+ 0.10M”,”Maghnite-H+ 0.15M”, “Maghnite-H+ 0.20M”, “Maghnite-H+ 0.25M”, “Maghnite-H+ 0.30M” and “Maghnite-H+ 0.35M”, respectively. The best yield was obtained using “Maghnite-H+ 0.25M”, so for this reason this sample was used to study the effects of catalyst on polymerization. Acid treatment of “Raw-Maghnite” causes a reduction in octahedral content (Al2O3) and resulted in an increase in the proportion of silica (SiO2) observed.
