Sodium polytungstate is a water-miscible, nontoxic, high-density and inorganic heavy liquid. 多钨酸钠是一种无毒、易配制、可循环使用、密度高的新型无机重液(HL)。
Results show that this method prohibits the poisonous heavy liquid and improves the gain rate of the fossil. 结果表明,该方法摒弃有毒重液(HL),提高了化石收获率。
Elementary discussion is made separately on improving the vibration sorting, introducing the magnetic separation, applying the heavy liquid separation, exploring the floatation technology and using the selective fragmentation principle and intensifying the screen sizing. 在采用振动选形技术的基础上,对应用磁分离技术、引入重液(HL)分离技术、探索浮选技术和应用选择性破碎原理及强化筛分分级几方面进行了探讨。
