摘要
Abstract
This paper takes natural quartz sand from a certain area in Indonesia as the research object.A systematic analysis of the raw sand was conducted using methods including polarizing microscopic analysis(PLM),X-ray diffraction(XRD),X-ray fluorescence spectroscopy(XRF),and standard sieve sieving.The results show that the raw sand has a SiO2 content of 99.62%,.Its particle size is concentrated in the range of 0.1～0.6mm,accounting for 84.53%,and fluid inclusions account for 4%～6%.Through process mineralogical analysis and experimental research,the raw sand was subjected to pre-classification followed by scrubbing,magnetic separation,and acid leaching operations.The optimized test conditions for each operation were determined(scrubbing time:15min;sodium hexametaphosphate dosage:7.5kg/t;three-stage magnetic separation;magnetic field strength:1.5T;acid leaching with 10%HCl+1%H2C2O4;acid leaching temperature:70℃).The final concentrated sand obtained has a SiO2 content of 99.89%,Al2O3 content of 0.0361%,Fe2O3 content of 0.0017%,and TiO2 content of 0.0220%,which meets the specifications for Grade III special optical glass sand.This mineral processing technology is simple and low-consumption,and is expected to provide technical support and reference for the industrial development and application of quartz sand resources in Indonesia.关键词
