补充资料:离子吸附型稀土矿
分子式:
分子量:
CAS号:

密度:2.0~2.5
性状:为白色、灰色、红色、黄色的松散沙粘土。
用途:用于提取稀土。
制备或来源:采矿是露天人工开采,不需粉碎,直接用小推车送进浸取池。化学处理提取稀土。
备注:离子吸附型稀土矿又称风化壳淋积型稀土矿,是仅我国才工业利用的新稀土矿物。由于含中度稀土高,冶炼方便,具有很强的国际市场竞争力。它是由富含稀土矿物和烯土副矿物的花岗岩和火山岩风化后,形成粘土矿物,解离出的稀土离子以水合离子或羟基水合离子吸附在粘土矿物上。吸附在粘土矿物上的稀土离子在水中不溶解也不水解,但遵循离子交换规律,可用化学法提取稀土。矿石为松散的沙粘土。
