THE EFFECT OF ATTRITION IN THE QUARTZ SAND BENEFICIATION

The quality of quartz sand can be improved by reducing the oxide coatings on the quartz grains. In this direction, a study has been made to consider the possibility of coatings removal from quartz sand by attrition cleaning. Tests were conducted in a laboratory attrition cell at different values of operating parameters: suspension density, attrition time and stirrer speed. Indicators of attrition efficiency were the content of the particles –0, 063 mm and content of main impurities (Al2O3, Fe2O3) removed through attrition process.
