Experimental study on beneficiation and purification of a quartz sandstone ore in Hunan
摘要
Abstract
In view of the high content of harmful components such as Al2O3 and Fe2O3 in quartz sandstone ore in Hunan,it was found that there were many cements such as illite,chlorite and iron-disseminated clay among quartz particles through process mineralogy research.In order to develop a suitable beneficiation purification process and improve the added value of products,the effects of scrubbing,flotation and acid leaching on the removal of cements,as well as the effects of the number of magnetic separation sections,the type of mixed acid,the amount of acid and the time of acid leaching on the purification of quartz sand ore were investigated by separation process test.The results show that the quartz sandstone ore with SiO2 grade of 94.23%,Al2O3 and Fe2O3 mass fraction of 4.52%and 0.14%can be purified to quartz concentrate with SiO2 grade of 99.63%,Al2O3 and Fe2O3 mass fraction of 0.06%and 0.01%by crushing-scrubbing-classification-magnetic separation-acid leaching process.The process has a significant purification effect on the quartz sandstone ore,and the obtained concentrate meets the requirements of quartz sand for high transmittance solar photovoltaic glass,which can provide technical reference for the beneficiation and purification of similar quartz sandstone ore.关键词
