Techniques Used to Analyze Minerals

Jan 28, 2019· It should be noted that minerals (or the mineral-containing sample) need to be ground (powdered) and solubilized first—but this is the case for almost all mineral analysis methods. Titrations that use EDTA are widely used for calcium-containing and sodium-containing minerals, but it can be used for many metallic minerals.
