Slag recycling With high quality iron ore grades with an iron content of 64 to 67 a blast furnace typically produces about 0.25 to 0.30 t of slag per t of pig iron In the case of inferior grade ores below 60 the amount of slag is typically 0.35 to 0.50 slag/t of pig iron 1 .Why Mineral Processing is Very Important for the Mining For example the extraction of 1 ton of lead from 30 grade ore by smelting requires almost 1.3 more energy than to extract the same quantity of Pb from 60 grade ore Besides in the grinding section there is a tip to reduce energy consumption As far as the ore requires fine liberation more energy for further grinding is needed But you can
