Influence of laboratory techniques on the geotechnical

The stone density of mining wastes is highly dependent on the mineralogy of the deposit rock and can vary substantially. Li & Rutherford (1996) found values of relative density varying between 2.70 to 2.87 for most of the bauxite from the southeast of Brazil. These values were justified due the high presence of gibbsite and low levels of iron ore.
