World production of ferrosilicon has been approximately 4 million metric tons (gross weight) per year over the past five years. Production of silicon metal in the world, with the exclusion of China, has been about 645,000 metric tons per year. Although firm data are lacking, China"s production of silicon metal is believed to be the world"s largest. China"s annual output of silicon metal was estimated at about 300,000 metric tons in 2002.
On a silicon content basis, Western world consumption of ferrosilicon averages about 1.7 million metric tons per year, and silicon metal averages about 968,000 metric tons per year. Because of its abundance in Earth"s crust, silica reserves around the world are more than adequate to sustain silicon production levels ind
