摘要
2003年,贱金属冶炼副产硫酸预计为46.8 Mt,其中大多是铜冶炼副产。到2010年,冶炼副产硫酸将达到60 Mt。最近几年,酸浸法制镍和湿法炼铜硫酸消耗量有所增加。根据今后15年镍的供需情况预测,到2020年酸浸法制镍硫酸消耗量将增加23 Mt,另外湿法炼铜硫酸消耗量也将增加4.2 Mt。
Production of sulphuric acid from the base metals smelting in 2003 is expected to attain 46. 8 Mt, most of this coming from copper smelting. By 2010, byproduct sulphuric acid will reach 60 Mt. In the recent year, sulphuric acid has been used in increasing quantities for leaching of copper deposits in SXEW system and nickel acid leach (AL) operation. Based on supply and demand of nickel in the next 15 years, sulphuric acid consumption via AL is expected to increase by 23 Mt. On the other hand, sulphuric acid consumption via SXEW will increase by 4. 2 Mt.
