The Density of Common Rocks and Minerals
Jan 23, 2020 The densities of rocks and minerals are normally expressed as specific gravity, which is the density of the rock relative to the density of water This isn't as complex as you may think because water's density is 1 gram per cubic centimeter or 1 g/cm 3 Therefore, these numbers translate directly to g/cm 3, or tonnes per cubic meter (t/m 3)Nov 25, 2014 Rock density information is needed for the estimation of ore tonnage, and also for determining the amount of contained metal; this is because mineralisation grades are usually reported as a ratio of the economically viable components, metals or minerals, to weight units (eg grams/tonne)Measuring and modelling of dry bulk rock density for Density (in lb/cu ft) = SG X 624 Density (SI units) = SG X Density of water (10 g/cc or 1000 kg/cubic metre) Specific Gravity and Porosity of Various Rock TypesRock Types and Specific Gravity
How to Find and Determine the Specific Gravity of a Rock
To determine the specific gravity of a mineral, you simply take a sample of ore of known size and put it into a volume of waterWeigh the water that was displaced by the mineral This will give you the ratio between the mineral and the water An example is if a mineral that weighs one hundred grams displaces twenty grams of water the specific gravity of the mineral is 5*0 or the mineral weighs Calculating density from mass and volume requires a simple formula: density equals mass divided by volume (D=m÷v) So, if the measured rock mass equals 9842 grams and the measured volume equals 3829 milliliters, using the formula gives the equation D=9842÷3829, showing the density of the sample equals 257 grams per cubic centimeterHow to Find the Density of a Rock SciencingCrushed aggregate, oneinch crushed concrete, recycled asphalt, 3/8inch pea gravel, 2inch sewer filter rock, and concrete and asphalt aggregate blends all weigh in at 107 tons Pit run gravel follows at 125 tons per cubic meter, regardless of whether it is 2inch or 4inch The heaviest of the crushed rock selections are Angular Rip Rap and Standard Weights for Crushed Rock Per Meter Hunker
