supplier of iron and manganese ore. The global manufacture of 780 million tons of raw steel in 1999, for example, required the mining of 992 million tonnes of iron ore and approximately 18 million tonnes of manganese ore. This production is from a nonrenewable reserve base. The size of this reserve base is certainly finite, but estimates
