摘    要:对某难选低品位金矿进行的研究结果表明,载金黄铁矿的嵌布粒度微细和易浮脉石矿泥是影响金精矿金品位和回收率的两个重要因素,在强化载金黄铁矿捕收的同时,选择合适的调整剂可以显著提高金的选矿指标。原矿金品位为1.69 g/t时,实验室闭路试验可获得金回收率69.85%、金品位20.47 g/t的金精矿。

关 键 词:金矿  黄铁矿  强蚀变围岩  浮选

Abstract:The result of the benefication experimental study on a low-grade refractory gold ore shows that, the fine-grained dissemination auriferouspyrite and the easy-floating gangue are the two important factors which influent the grade and recovery of the gold concentrate, the gold ore dressing indexes can be improved by choosing appropriate adjustment agents and enhancing the collection of auriferouspyrite. The gold concentrate with the recovery of 69.85% and the grade of 20.47g/t can be obtained through the lab closed-circuit test while the grade of the raw ore is 1.69g/t.
Keywords:gold ore  pyrite  strong wall-rock alteration  floatation
