Excerpt from Relation Between Specific Gravity and Iron Content of Rocks From the Red Mountain Formation, Alabama An understanding of specific gravity is useful for purposes other than the estimation of the iron con-tent of rocks. The bulk specific gravity of ores is needed ln order to calculate ore reserves. Measure ments based on differences of specific gravity of rocks are recorded by both gravity and seismic geophysical surveys; and, although suc cessful geophysical techniques for prospecting for hematite ores have not yet been developed, a study of specific gravities of the ores and surrounding rocks will be basic to the development of future tech niques. Porosity of the rocks can be quickly estimated from petro graphic studies made in conjunction with specific-gravity measure ments. Finally, sampling programs can be conducted more cheaply by using rapid specific-gravity determinations as the first step in the selection of samples for further work. For example, iron-rich beds from diamond-drill cores can be selected for chemical analysis on the basis of high specific gravity. The dilemma of either having to analyze large quantities of low-grade rock chemically or overlooking ore zones can be cheaply resolved by using mathematical quality-control tech niques, which have revolutionized production-line control in industry.
