Ore Conservation is a Major Benefit When Scrap
The methods for extracting iron ore include drilling, blasting and excavating. Once iron ore is removed from the ground, the next production phase is beneficiation. That involves dissolving rock material to get the mineral. Iron in its purest form is then shipped to global markets. Mining and refining metal ores
