钼精矿铅高原因分析及对策

ANALYSIS AND COUNTERMEASURE ON HIGH CONTENT OF LEAD IN MOLYBDENUM CONCENTRATES

查清原矿含铅升高 ,认为抑制剂用量不足及方铅矿过磨是钼精矿含铅高的主要原因。指出加强再磨分级管理 ,改变磷诺克斯合成配比及添加制度是保证钼精矿含Pb≤ 0 .0 40

It is proved that the reason of higer content of Pb is increasing of content of Pb in primary mineral,deficiency of inhibitor and over grinding of Pbs.It is pointed that enhancing management by different regrinding levels and changing compound proportion of P-Nokes are the key technical measures to ensure the content of Pb is no more than 0.040%.
