摘要
对新疆地区石英石的提纯流程进行了初步探索。以新疆某地石英矿石为原矿,采用"粗碎-水淬-中碎-细碎-磁选-浮选-酸浸"工艺流程,在破碎、水淬后,对磁感应强度,浮选过程中的pH值、捕收剂用量,酸浸的浸出时间、液固比、浸出温度等条件进行了详细试验,结果表明,通过磁选、浮选等物理提纯后,在浸出时间4 h、液固比2:1、浸出温度80℃的情况下,对SiO_2含量99.27%的原料进行提纯,最终可以得到SiO_2含量99.99%以上,总杂质含量小于75 μg/g的高纯石英砂。
A preliminary study on the purification process of quartz in Xinjiang region was carried out.After crushing and water quenching,the process of"coarse crushing-water quenching-intermediate crushingfine crushing-magnetic separation-flotation-acid leaching"was adopted with quartz ore in a certain area of Xinjiang as the original ore.The magnetic induction intensity,pH value in flotation process,dosage of collector,leaching time of acid leaching,liquid-solid ratio and leaching temperature were tested in detail.The results show that after physical purification,such as magnetic separation and flotation,the raw ore with SiO2 grade of 99.27%is purified under the conditions of leaching time of 4 hours,liquid-solid ratio of 2 to 1and leaching temperature of 80℃.Finally,high purity quartz sand with SiO2 taste over 99.99%and total impurity content less than 75μg/g can be obtained.
