That seems like a very large number for the construction of any industrial installation. Just poking around the net the numbers I found were $220/ton of pig iron produced, and another source that claimed a $2.5b cost in 1980 and $5b today. If the $220/ton figure is accurate a $100b blast furnace would be producing 455m tons of pig iron a year. According to wikipedia a modern furnace can produce about 5-6m tons per year.
