Sio Sand Grinding Process

In this work nanoparticle silica was synthesized using silica sand and quartzite by top down approach using ultrafine grinding. Silica sand was obtained from Bangka island while quartzite rocks from Rokan Hulu, Riau. Both samples have good SiO2 value about 98% and increase up to 99.7% after leached with sulfuric acid in room temperature

    Low temperature production of wollastonite from limestone

    Mar 01, 2014 Limestone had to be ground for an hour to get a median size (d 50) of 11.57 μm, while silica sand had a median size (d 50) of 12.28 μm after 2 h of grinding. By performing the grinding process separately, a uniform degree of liberation was achieved which involved the reduction of a similar particle size and resulted in isolation of minerals of the limestone and silica sand
