Металлургийн хэд хэдэн арга бий: 1. Пирометаллурги бол дулааны аргаар маш өндөр температурт хүдрийг хайлж цааш нь шат дараалан химийн урвал явуулан цэвэр металл гаргадаг арга юм. Энд төмрийн хүдрийг хайлуулах байшин зуухны аргыг хамааруулж болно. 2. Карботермийн арга. Үүнд нүүрс буюу нүүрсний оксидоор хүдрийг ангижруулдаг.
