摘要
铜冶炼炉渣中二氧化硅含量是一个重要指标,直接决定熔炼过程的特性,氟硅酸钾容量法测定二氧化硅简单,快速,重复性较好。本文探讨了用氟硅酸钾容量法在测定铜炉渣中注意事项及操作要点。
The content of silica in copper smelting slag is an important index that directly determines the characteristics of smelting process. The determination of silica by potassium fluosilicate capacity method is simple, rapid and reproducible. This article explored the use of potassium fluosilicate capacity method in the determination of copper slag Matters needing attention and operation.
