Traditional interpolation techniques in geostatistics were used to represent density spatial distribution in a block model, similarly to those used for grade estimation. This approach was developed and applied at a Brazilian iron ore mine. The results indicate MRMR are underestimated if density uncertainty is not considered.

The density of iron ore dust is typically around 2,500-3,000 kg/m³, while the density of solid iron ore is around 4,000-5,000 kg/m³. The higher density of solid iron ore is due to the particles being closely packed together in a solid state compared to the looser arrangement of particles in dust form.
