According to the characteristics of a lead concentrate containing high grade of zinc, antimony, silver, using the oxygen-enriched side-blowing continuous smelting technology deal with it. Technical process is that complex lead materials put into oxidation furnace smelting first, then output small amount of lead and high lead slag. high lead slag through chute continuous was put into the smelting reduction furnace, output most lead and reduction slag. Finally, reduction slag through chute continuous put into the fuming furnace smelting, output zinc oxide dust and smouldering slag. Production practice shows that lead recovery is more than 97%, gold and silver is more than 99%, antimony is more than 95%, volatile rate is less than 10%, comprehensive coal consumption is less than 11%, and the average smelting cost is 110 dollar /t Pb. |
