iron slag processing

The process of extracting iron from ore produces great quantities of poisonous and corrosive gases In practice these gases are scrubbed and recycled Inevitably however some small amounts of toxic gases escape to the atmosphere A byproduct of iron purification is slag which is produced in huge amounts
