Heavy Mineral Analysis - Heavy Minerals Analysis

Heavy minerals. Most sands are composed for 99% of light minerals such as quartz (s.g. 2.65) and feldspar (s.g. 2.54 – 2.76). Therefore, sands are mainly distinguished on the basis of their variable heavy mineral content. Heavy minerals are considered to be those minerals with a specific density greater than 2.8. Separation
