density for mining rock

Density of Rocks and Soils Chemistry LibreTexts

The Soil and Rock Density Tables show that the density of classic sedimentary rocks varies, becaue it increases (under overburden pressure) as the rocks are progressively buried. A process called cementation, where disolved minerals fill the interstices, also decreases the porosity and increases the density.

What Are the Five Properties of Rocks? Reference

The shape of the rock may be round, square or rectangular. Some rocks form in distinctive shapes, while others do not. In some types of rocks, such as sedimentary, shape may be used to describe the shape of the sediments within the rock. Texture explains how a rock feels. Smooth, rough, hard or soft are common descriptions.
