During the 1890s, Thomas Edison launched a New Jersey mining operation to address an iron ore shortage. He designed rockcrushing technology and an electromagnetic ore separator to extract lowgrade ore from crushed boulders. The final product a briquette made of powdered iron ore didn't do well commercially, especially after highgrade ore was discovered around Lake Superior.

Ore. a rock in which a valuable or useful metal occurs at a concentration sufficently high, relative to average rocks, to make it economically worth mining. Concentration Factor. The way a given ore is described in terms of the enrichment. The higher the concentration factor, the richer the ore, and the less of it needs to be mined to extract a ...
Preconcentration relies on heterogeneity in the ore. That is, at some scale, there must be discrete highergrade and lowergrade zones in the ore that have the potential to be separated. For example, there may be discrete veins of valuable minerals within poorly mineralized hostrock or sulphide breccias containing clasts of unmineralized rock.
