Experimental Study on Mineral Processing and Purification of Quartz Rock in a Certain Area of Jiangxi Province
Taking into account the high Al2O3 and Fe2O3 content of a quartzite deposit in Jiangxi Province,this study conducted mineral processing experiments to purify the raw material using a crushing-grinding-classification-magnetic separation-flotation-acid washing process.The SiO2 content of the original quartzite ore was 94.54%,while the Al2O3 and Fe2O3 contents were 2.42%and 0.76%,respectively.The study resulted in a quartz concentrate with a SiO2 content of 99.36%,Al2O3 and Fe2O3 contents of 0.062%and 0.008%,respectively,with a recovery rate of 77.16%and a yield of 73.34%.The results meet the requirements for industrial grade products and have good application prospects.
