ChemTeam Density

Density (whose most common symbol is the lowercase letter d) is defined as mass per unit volume. Density is calculated by dividing the mass of an object by its volume. This is shown in equation form, as follows Density = mass volume. By the way, the lower-case Greek letter rho, ρ, is also used to symbolize density.

Density (unit weight) is a measure of weight per unit volume and is expressed in lbs/ft or kg/m. The density of fresh concrete is similar to the density of hardened concrete. After the unit weight is determined, yield can be calculated. Yield is the ratio of total weight of mix material batched for a designed volume to the actual concrete

3. Crushing At the processing plant, the taconite is crushed into very small pieces by rock crushing machines. The crushers keep crushing the rock until it is the size of a marble. The rock is mixed with water and ground in rotating mills until it is as fine as powder. 4. Separation The iron ore is separated from the taconite using magnetism.

How do I Calculate Density? Calculating Density

Another tricky thing about density is that you can't add densities. If I have a rock that is made up of two minerals, one with a density of 2.8 g/cm 3, and one with a density of 3.5 g/cm 3, the rock will have a density between 3.5 and 2.8 g/cm 3, not a density of 6.3 g/cm 3.
