A comprehensive recovery process of iron symbiotic non-ferrous metal copper, lead and zinc, including medium and weak activation and weak collection of copper, lead and zinc mixed floating, strong drug removal and low concentration copper and lead and zinc separation, and small stroke and large stroke times. The fine mud shaker separates lead and zinc mineral. With the help of the hydrophobicity of copper-lead-zinc minerals after iron selection, the total mixing selection of copper-lead-zinc weak activation and weak collection is realized, which saves the cost of chemicals and avoids the poor separation technical indicators of copper and lead-zinc caused by the strong activation and strong collection of the traditional process. The problem of high mutual content of concentrates; copper and lead and zinc are separated by low concentration and strong drug removal. On the basis of dilute sulfuric acid and pyrosulfite cleaning and activation, the natural floatability of copper minerals is used to realize the separation of copper and lead and zinc minerals; The lead-zinc concentrate adopts a fine mud shaker, small strokes and large strokes without flushing water to strengthen the separation process of fine-grained lead and zinc minerals, and obtains a single lead concentrate and zinc concentrate, which solves the problem of iron symbiotic copper, lead and zinc separation. It is impossible to obtain a single lead concentrate and zinc concentrate, and the separation efficiency is low, the concentration of the concentrate is high, and the value of the concentrate is low. |
