| 摘 要： | 针对餐饮废油脂的危害，为实现废油脂有效再利用，实验将废油脂经过皂化-盐析-水洗-酸化-水洗-干燥处理制得混合脂肪酸，在温度为120 ℃、赤磷为催化剂的反应条件下，以稳定的速率通入M，反应8 h后制得一种α衍生脂肪酸浮选药剂-M-105，并将其用于尖山磁选铁精矿反浮选，获得铁精矿品位为70.26%，回收率为83.00%的良好指标。

| Abstract: | In order to eliminate the waste cooking oil harm on human health and reuse it effectively, mixed fatty acid extracted from waste cooking oil by a series of processing:saponification-salting-out rinsing-acidification-drying, reacted with M inputed at a steady rate, when the reaction temperature at 120 ℃，red phosphorus as catalyst and reaction time is 8 h. The α derived fatty acid--M-105 was obtained and applied into the reverse flotation of Jianshan magnetite. The satifactory results of a grade of 70.26%, recovery of 83.00% was obtained. |
