如果在利用各種不同鐵品位和雜質(zhì)的精礦時(shí)，獲得同樣成分（等級(jí)）的生鐵，則按每噸生鐵計(jì)算。在生鐵的質(zhì)量（按有用成分或有害雜質(zhì)含量計(jì)）不同時(shí)，經(jīng)濟(jì)計(jì)算則進(jìn)行到獲得每噸鋼和相應(yīng)的副產(chǎn)品為止。在此種情況下，在煉鋼生產(chǎn)中與生鐵加工有關(guān)的附加費(fèi)用（或去掉銷(xiāo)售刮產(chǎn)品的收益，如磷渣、釩渣等）加到每噸生鐵中去的條件下，計(jì)算工作可限于高爐冶煉。蘇聯(lián)確定鐵礦石選礦深度的技術(shù)經(jīng)濟(jì)計(jì)算是由黑色冶金科學(xué)研究設(shè)計(jì)院的研究員進(jìn)行的。
