    In addition, the full utilization of the method is dependent on a complete understanding of the density relationships of ores and their contrast with the country rocks. This is made particularly difficult by the wide range of densities of Fe ores that can lead to the association of both positive and negative gravity anomalies with Fe ore bodies.

  • DENSITY and SPECIFIC GRAVITY

    2015-6-6 · Densities of minerals Most common minerals in Earth’s crust have specific gravities ranging from 2.6 to 2.8. Quartz, for example, has a specific gravity of 2.65, calcite 2.72, and the common feldspars from 2.60 to 2.75. Among all minerals, densities range widely, from about 1.5 to almost 23. Here’s a short list, in three categories:
