Iron Mining: The Problems Of Plenty

There are no particular nor unique features of iron mining that are not shared in some degree by all mining ventures everywhere. There are, however, at least three problems that have acquired a special emphasis from a unique cause. That cause is the embarrassment of riches under which the industry is suffering. The most obvious' feature of iron mining today is the copious abundance of usable ore and its almost universal distribution over the face of the earth. By the term "usable ore" is meant ore that is amenable to reduction by the usual and conventional processes. Amidst this plenty, three problems become acutely emphasized: 1. The geographic location that will provide a mine with the best market opportunity. 2. The size of the orebody that will be required to' return the preproduction investment. 3. The geometry and configuration of the orebody that will permit quality control measures to be effectively executed.
