Analyze whether the temperature needs to be raised to 1200 for pyrite slag℃
Thread Content
I would like to ask the experts: Is it necessary to raise the temperature to 1200°C for analyzing pyrite slag, and is there any such analytical procedure? Thank you.
What project is being analyzed?
If it is to analyze sulfur, it is very likely.
In the sulfuric acid industry, only the available sulfur needs to be analyzed; that is, even when the temperature in the tubular electric furnace is kept at 800°C, if the slag is to be used in the steel industry, it is necessary to know the total sulfur content. In other words, when conducting analyses, the temperature in the tubular electric furnace should be controlled at 1200°C.
When analyzing available sulfur, the temperature is 800 and that for total sulfur is 1200; the operating procedures remain the same, as do the equipment used
It seems that in the sulfuric acid analysis procedures, precipitation is used to determine the total sulfur content; if a temperature of 1200 degrees is used, copper oxide must be added. Is the result the same without adding it?
