Process development of silica extraction from RHA: a cradle

India is one of the major rice-producing countries. Rice husk is a major agricultural by-product from rice production, which is used as a fuel in boilers. Its use as fuel produces huge amounts of silica-rich rice husk ash (RHA). This paper aims at providing an overall assessment of environmental impacts associated with the extraction of silica from In this figure, the size distribution for the silica sand before milling is d(0.5) = 293.148 µm 9 (Fig. 1a) and after ball milling process the size distribution of silica change to d(0.5) = 5.020Particle size distribution (a) before milling and (b) after 4
