Most new steel mills were located near the southern end of Lake Michigan- Gary in Indiana Chicago and other communities. The main raw materials continued to be iron ore and coal but changes in steelmaking required more iron ore in proportion to coal. Thus new steel mills were built closer to the Mesabi Range to minimize transportation cost.

Silica Minerals Education Coalition

Silicon compounds are the most significant component of the Earth s crust. Since sand is plentiful easy to mine and relatively easy to process it is the primary ore source of silicon. The metamorphic rock quartzite is another source. Silicon (Si) is a semi-metallic or metalloid because it has several of the metallic characteristics.
