补充资料:矿渣
分子式:
CAS号:
性质:(一)又称浸出渣。铀矿石(或精矿)在酸浸出或碱浸出过程中未被酸或碱浸出的那部分矿物。由于浸出过程的选择性,大部分脉石矿物残留在矿渣中。也有部分已被酸浸出到溶液中的杂质离子(如Fe3+),由于浸出液酸度的降低,又水解沉淀而复人渣中。为了防止浸出到溶液中的铀的水解,浸出液需保持一定的过剩酸。(二)高炉炼铁熔融的矿渣在骤冷时,来不及结晶而形成的玻璃态物质。呈细粒状。熔融的矿渣直接流入水池中冷却的又叫水淬矿渣,俗称水渣。矿渣经磨细后,是水泥的活性混合材料。含SiO2多的矿渣为酸性矿渣,含Al2O3和CaO多的为碱性矿渣。碱性矿渣的活性比酸性矿渣高。矿渣由于具有一定的自身水硬性,不宜长期存放。
