45.5g displaces 30.8 ml,,what is the density
The solid density of iron ore generally lies between 3.35 and 5.6 tonnes per cubic metre, depending on the particular characteristics of the ore being considered. When the ore is broken up, air spaces are formed between the particles of ore, and the "apparent" density will be lower. The loose bulk density is one measure, the compacted bulk density is another, and the fluidised bulk density is yet another. The loose bulk density is measured on a sample of loose ore, that has not been allowed to self-compact over time, and has not been mechanically compacted. It will generally measure between 50% and 60% of the value of the solid density.
The density of Iron ore solid is 4/4.5 T/cu.m as against dust at 2.8/3 T/cu.m
abrasive bulk density: 120-150 lb/cu.ft
Specific gravity is equal to the density of the iron ore divided by the density of water. The densities change with temperature, so I will assume a temperature of 4 degrees C for this calculation. At this temperature the density of water is 1000kg/m^3. There are various types of iron ore with varying densities. I found a reference table that states the density if iron ore ranges from 2100 to 2900kg/m^3. I will use the average: 2400kg/m^3. The reference table doesn't give a temperature, but oh well. I would choose 4 degrees C if I could. This gives us: specific gravity=(2400kg/m^3)/(1000kg/m^3) =2.4 Notice there are no units. This is a dimensionless parameter. It says iron is 2.4 times as dense as water. It will sink.

The density of iron ore is variable. Iron ore refers to a rocktype that contains iron minerals. The type and concentration of the iron minerals as well the type and concentration of non-iron minerals determines the density of the iron ore. Typical high grade iron ore is approximately 65% hematite and 35% other (commonly silicate). The density of hematite is approximately 5 g/cc and a general density for crustal rocks (silicates) is approximately 2.67 g/cc. Therefore iron ore that is 65% hematite and 35% silicate would have a density of approximately 4 g/cc.

Spiral Concentrators are used in Iron ore beneficiation plants for Gravity Separation. It separates the higher density Iron Ore from Silica based on density difference as concentrate, middling & tailing.
Density is just one property of rock that can be utilized in the discovery of ore deposits.
Density = mass/volume, So, Density = 57g/29cm3 = 2.0g/cm3* The number on the calculator is 1.965517241, which is rounded to 2.0 because of significant figures.

Uranium is rarely found as a free metal, it is combined with other materials as uranium ore.
density = mass / volume = 62g / 21.9 cm³ ≈ 2.8 g/cm³

Uranium ore is not...uranium ore !
