The BHP smelter at San Manuel produces 450,000 gallons of sulfuric acid a day, or enough to fill 12,500 rail cars or 52,000 trucks every year. BHP Copper uses 18 percent of the sulfuric acid it makes for leaching its own oxide ore. Another 40 percent of its sulfuric acid production is sold to other mining companies for their leaching operations.
