Lead zinc ore refers to a mineral rich in the metal elements lead and zinc, with a blue gray color and a hardness of 1.5. It is the softest metal lead and one of the earliest metals extracted in history. Lead zinc has been widely used in various fields. The main type of lead-zinc ore is sulfide ore, while oxide ore is relatively rare. The main minerals that make up lead-zinc sulfide ore are galena, sphalerite, or sphalerite; The main minerals of lead-zinc oxide ore are galena, siderite, and sphalerite.

After being ground by a ball mill, the fine ore will be sent to the next process: grading. Spiral classifier is an efficient new equipment for reselection and sorting. The spiral classifier uses different proportions of solid particles to precipitate at different liquid velocities, washing and classifying ore mixtures. Then the mineral particles are sent into the flotation machine, and different drugs are used according to the characteristics of the minerals to separate them from other substances.
