选别物料平衡计算数学模型的探讨

Discussion on the Mathematical Model of Material Mass Balance Calculation for Mineral Processing

经典的多金属矿石选矿流程平衡数学模型充分尊重了化验的精矿品位,忽视了调整后的原矿和尾矿品位的合理性。针对经典数学模型的不完善之处,进行了升级改造,新的数学模型兼顾了原、精、尾品位,对各产物的品位进行了更系统、更全面、更贴近实际的调整,因而调整的结果更科学、更合理、更可靠,能满足矿山选别指标调整的需要。

The classic mathematical model of multi-metallic mass balance fully respected the concentrate grade in testing,bur ignored the reasonability of adjusted raw ores＇ and tailings＇ grade.In view of these disadvantages,this classical mathematical model was upgraded and improved.The upgraded mathematical model takes into account the grade of raw ores,concentrates and tailings.The grade analysis of each product is more systematic and comprehensive,making it closer to the actual adjustment.So after adjustment,the results are more scientific,rational,reliable,which can meet the needs of the index adjustment for beneficiation.
