本发明公开了一种用于浸取离子型稀土矿的浸取剂及其浸矿方法，采用含稀土尤其是镧、铈的盐溶液作为浸取剂，控制浸取剂中除氢离子以外的阳离子浓度为0.06-0.12mol/L，利用高价阳离子对离子型稀土矿浸取能力高的特点，在低浸取剂浓度的条件下实现稀土的高效浸取，同时新增了富余镧铈元素的应用领域，减少了镧铈元素的浪费。特别的，采用浸取剂管道浸出的方式，有效提高稀土浸出液浓度。 According to the leaching agent and the ore leaching method, a salt solution containing rare earth, especially lanthanum and cerium is adopted as the leaching agent, the concentration of positive ions except hydrogen ions in the leaching agent is controlled to be 0.06-0.12 mol/L, the characteristic that high-valence positive ions have high leaching capacity on the ionic rare earth ore is utilized, the leaching efficiency of the ionic rare earth ore is improved, and the leaching efficiency of the ionic rare earth ore is improved. Efficient leaching of rare earth is achieved under the condition of low leaching agent concentration, meanwhile, the application field of surplus lanthanum and cerium elements is increased, and waste of the lanthanum and cerium elements is reduced. Particularly, a leaching agent pipeline leaching mode
