Low global iron ore prices have reduced Liberia’s production and exports over the last few years as multinational iron ore companies around the world significantly scaled down their operations. However, ArcelorMittal continues mining Mount Gangra, one of the mountains within its concession area.
The sample mass can then be reduced to 1 g through a sequence of mass reduction and size reduction (C to D to E to F). 1.9. Problems. 1.1. Iron ore was sampled before stock piling with a stacker. One hundred samples taken from the stacker–conveyor showed a standard deviation in the iron assay of ±0.5%. The ore assayed, on average, 59% Fe.

In general, metals are more dense than non-metals. (1) For example, at 25°C the density of metallic lead is 11.4 g mL-1 while the density of non-metallic sulfur is only 2.0 g mL-1. This means that the mass of 1 mL of lead would be 11.4 g while the mass of 1 mL of sulfur would be only 2.0 g.
