Silica sand is the raw material for the production of silicon metal and ferrosilicon. Silicon metal is used in the production of alloys based on aluminium, copper and nickel, Ferrosilicon is a major alloying ingredient for iron and steel. Metal ores are purified in the furnance by silica sand that is transformed into metal slag.
