Preparation method of sectional type phosphorite impurity removal flotation collecting agent and flotation process of sectional type phosphorite impurity removal flotation collecting agent

The invention relates to the technical field of phosphorite flotation, in particular to a preparation method of a sectional type phosphorite impurity removal flotation collector and a flotation process of the sectional type phosphorite impurity removal flotation collector, and the preparation method comprises the steps of raw material preparation, raw material treatment and vacuum drying. According to the invention, anions and cations lose alkaline metal ions and H < + > ions in an organic solvent in advance, charge entanglement or precipitation is avoided, and a stable ionic state is kept. The agent is added in the flotation process, positive and negative ions exist in ore pulp at the same time and can react with minerals at the same time, the synergistic effect of the negative ion collecting agent and the positive ion collecting agent is greatly achieved, and the purpose of good mineral separation is achieved. 本发明涉及磷矿浮选技术领域，具体为一种分段式磷矿除杂浮选捕收剂的制备方法及其浮选工艺，制备方法包括原料备用、原料处理和真空干燥，有益效果为：相较于现有的捕收剂，本发明使得阴阳离子在有机溶剂中提前失
