Two-Stage Continuous Process for the Extraction of Silica from Rice
A two-stage continuous process was developed for improved silica extraction from rice husk. The two-stage continuous process consists of attrition ball milling and alkaline leaching methods. To find the optimum conditions for the continuous process, the effects of alkaline leaching parameters, such as the alkaline solution type and reaction conditions, on the silica extraction yield were

Development of a Beneficiation Flow Sheet for Processing Silica Sand
The silica sand is an assemblage of individual silica grains in the size range upto 2 mm. Sand can be formed in nature by natural weathering of sandstone and quartzite or mechanically by crushing a sandstone /quartzite or by a process of flotation whereby the various constituents in a pegmatite or kaolin mixture are separated.
