  • Title: Evaluation and beneficiation of silica sand and

    Attrition scrubbing trials were performed on various size fractions to assess the benefit of attrition scrubbing in upgrading the silica sand Upgrading the silica sand included removing or reducing the content of the contaminant oxides (ie, Al2O3, Fe2O3, TiO2, CaO, and MgO) and the heavy mineralsSilica purifying process can include various steps such as comminution, washing and desliming, attrition scrubbing, drying, hot acidic leaching, scrubbing, flotation, magnetic separation and so onReduction of Iron Content from Silica Sand by Scrubbing31 Scrubbing Time The silica yield improved to an optimum of 9987% using an attrition scrubber operated at 1,250 rpm for 20 min (Fig 3) The SiO2 content was decreased by 15% with further increase in attrition time beyond optimum where no remarkable improvement in silica content was noticed The silica rocks achieved Fe2O3PhysicoChemical Study of Silica Rocks from the East
