Carbonation conversion of lead-smelting processes generally lead concentrate can be processed, the processing may be low-grade lead concentrate, lead-based gold ore pyrometallurgical treatment process is difficult, and the like, have been tested multi-element chemical analysis of the ore, the following table . The particle size distribution of the ore is shown in the table below. These ore X- diffraction and EDS measurement, the main phase ores galena, pyrite, yellow copper ore, sphalerite and quartz.
