Mined lead-zinc ore first by Jaw crusher for initial crushing, and after fine crushing to a reasonable degree through by elevator and vibrating feeder evenly sent into ball mill, the ball mill for ore crushing and grinding. After ball mill grinding, the fine ore will sent into next process: classification. Spiral classifier is efficient re-election new equipment for sorting, spiral classifier with different proportion of solid particles precipitated in the liquid velocity different principles, the ore mixture was washed, grading. And then the mineral particles are fed into flotation machine, depending on the mineral characteristics with different drugs, the minerals and other substances to be separated
