Developing a Low Hazardous Method to Determine Fe Grade of Iron Ores

The presence of iron sulfide minerals and the lack of dissolution of iron in these minerals in hydrochloric acid causes the titration results to be not accurate, and consequently, the obtained Fe grades to be less than the actual amount. In the proposed method, Fe–S bonds are broken in nitric acid a...

Description
Summary:The presence of iron sulfide minerals and the lack of dissolution of iron in these minerals in hydrochloric acid causes the titration results to be not accurate, and consequently, the obtained Fe grades to be less than the actual amount. In the proposed method, Fe–S bonds are broken in nitric acid and then iron is dissolved using hydrochloric acid. Increased safety and reduced analysis time are some of the advantages of this method.
