根据矿石磁性和表面光学性质,从理论上论证大屯选厂原矿的最高拣选效率。对大屯硫化矿块矿的磁性与光度的测定和分离结果表明,它们可采用磁—光拣选法拣选出约占原矿10—20％的可以丢弃的废石。在磁性—光度拣选法中,磁拣法较为优越。当原矿品位为:Sn0.251％、Cu0.355％、Fe24.88％、S12.53％,丢弃的
According to the magnetic and surface optical properties of ores, the highest sorting efficiency of ores in Datun dressing plant is theoretically demonstrated. The determination and separation of magnetic and photometric results of the Datun sulphide ores have shown that they can use the magneto-optical sorting method to pick out the discarded waste rock which accounts for about 10-20% of the ore. In the magnetic-photometric sorting method, magnetic sorting method is superior. When the ore grade: Sn0.251%, Cu0.355%, Fe24.88%, S12.53%, discarded
