我厂处理原矿为矽化较深的矽质白云石。主要有用金属矿物:铅矿物以方铅矿、白铅矿为主,次为铅矾矿。锌矿物以菱锌矿、异极矿为主,次为闪锌矿。脉石矿物以白云石、石英为主,次为重晶石、萤石等。人选原矿含铅10～16％,铅氧化率50～55％;含锌3～5％,锌氧化率70～75％,为铅高锌低的铅锌氧化矿石。采用先硫后氧浮选流程生产硫化铅精矿与氧化铅精矿两种产品。锌由于氧化率较高,目前尚未进行回收,弃之于尾矿。硫化铅浮选药剂有碳酸钠、硫酸锌、丁基黄药、二号油。氧化铅浮选药剂原有碳酸钠、硫酸锌、水玻璃、硫化钠、丁基黄药与二号油,用量见表1。
I plant for the processing of ore for the siliconized deeper dolomite. The main useful metal minerals: lead minerals to galena, mainly white lead, lead times for lead ore. Zinc ore to calamine, hemimorphite-based, secondary sphalerite. Gangue minerals to dolomite, quartz, followed by barite, fluorite and so on. Raw ore ore lead 10 ~ 16%, lead oxidation rate of 50 ~ 55%; zinc 3 ~ 5%, zinc oxidation rate of 70 ~ 75%, for the lead high zinc zinc lead-zinc oxide ore. Sulfur flotation process using sulfur after the lead sulfide concentrate and lead oxide concentrate two products. Due to the higher oxidation rate, zinc has not yet been recovered and is discarded at the tailings. Lead sulfide flotation reagents are sodium carbonate, zinc sulfate, butyl xanthate, two oil. Lead oxide flotation reagent The original sodium carbonate, zinc sulfate, sodium silicate, sodium sulfide, butyl xanthate and the second oil, the amount shown in Table 1.
