摘　　要：在铜冶炼系统当中,铜精矿,辅料石英石及铜炉渣都是含硅的复杂化合物,准确测定硅的含量对铜冶炼生产至关重要。简要阐述了硅酸脱水重量法、氟硅酸钾容量法及硅钼杂多酸光度法测定硅的方法原理及相关注意事项。在实际分析工作当中,应根据物料含硅量不同,选择合适的方法,就能得到准确的结果。In the copper smelting system, copper concentrate, auxiliary quartzite and copper slag are complex compounds containing silicon. It is very important to accurately determine the content of silicon for copper smelting production. The principles of silicic acid dehydration gravimetric method, potassium fluosilicate volumetric method and silicon molybdenum heteropoly acid photometric method for the determination of silicon were briefly described as well as some points for attention. In the actual analysis work, the right method should be chosen according to the different silicon content of the material, and the accurate result can be got.
