Abstract
The invention discloses a lead-zinc ore preferential flotation method, which relates to the field of mineral processing, and comprises the following steps: S1, pretreating lead-zinc ore to remove impurities in the lead-zinc ore to obtain ore pulp; s2, a lead preferential flotation reagent is added into the ore pulp, lead concentrate and zinc concentrate are obtained, and the adding amount and adding time of the flotation reagent are adjusted through an intelligent control system; s3, according to the ore property and the flotation effect, operating parameters of a flotation machine are intelligently adjusted; and S4, a dynamic simulation model of the flotation process is established, and the flotation process is optimized in real time through a model prediction control algorithm in combination with real-time monitoring data. Through intelligent control and dynamic simulation model optimization, the flotation efficiency and selectivity of the lead-zinc ore are improved, the problems of low flotation efficiency and poor selectivity in the prior art are solved, and the recovery rate and economic benefits of the lead-zinc ore are improved.
