Our country is in industrialized primary level, future is quite long period, to all sorts of mine product requirement will be in high level condition, accumulative total demand is tremendous. The United States is to develop the industrialized big country that rise first, wear out condition of product of the mine in its industrialization process can offer our country to consult. The finite sex of mineral products resource and the mankind of infinite sex requirement that industry expands demand must be developed abstinently moderately use mineral products resource, to assure ten population of our country can can develop continuously, development of resource of our country mineral products should change contented home to need in the round, export mine product and relevant product actively no longer.
One, product of American main mine is produced and consume a circumstance
American mouth is made an appointment with 300 million, it is to develop the industrialized big country that rise first, nearly hundred years come to the United States product of of all kinds mine and relevant product production and consumption present different metabolic pattern, development of resource of its mineral products is produced and metabolic rule of consumption weaves to our country mineral products resource develops long-term program to have referenced sense.
Iron ore and steel: Crop of American iron ore achieved the history 1952 top level 120 million tons, iron ore consumption achieved 145 million tons 1954, maintain nearly 5 years in 71 million ~5600 10 thousand tons between 1900~1949 year during iron ore of most a particular year inspects consumption to be more than crop, iron ore imports a quantity not to exceed 5 million tons completely (it is only outlet 8 years only, the amount does not exceed 2 million tons) . 1954~1990 year iron ore inspects consumption to be more than crop, its are poor in 1200~7000 10 thousand tons between, 1991~2007 year narrow 15.8 million ~400 10 thousand tons between. 1900~2007 year crop of accumulative total of American iron ore 7.045 billion tons, accumulative total inspects consumption 8.253 billion tons. American steel output achieved the history 1973 highest 137 million tons, inspect consumption to achieved the history 2006 top level 120 million tons. 1914~1958 year American steel is only outlet, 1959~2007 year for only import. 1900~2007 year crop of American steel accumulative total 7.664 billion tons, accumulative total inspects consumption 6.694 billion tons (graph 1) .
Capacity of resources of American iron ore is 110 billion tons, reserve 6.9 billion tons, basically be low grade Tie Suiyan iron ore, course of study of commercial chemical industry uses need mineral separation and nodulizing. Resource of American iron ore does not have an advantage on quality, although the United States has advanced iron and steel to manufacture a technology, but it did not enlarge iron and steel to produce total dimensions, satisfy domestic need through increasing steel to import an amount however.
