| Abstract: | The paper introduced a method of measuring free calcium oxide in dolomite half roasting product,by using magnesium chloride solution to leach calcium oxide as soluble calcium salt,then titrate calcium ions using EDTA standard solution.This method is different from other traditional methods,it can be easily operated,and needs short analysis time,accurately and quickly,with good repeatability.It's suitable to the control analysis of dolomite roasting process. |
