从金宝山铂钯浮选尾矿中再回收铂钯的研究

Recovery of Pt and Pd from the flotation tailings of Pt-Pd ore in Jinbaoshan Mine

根据金宝山铂钯浮选尾矿的矿石性质 ,采用磁选 -磨矿 -浮选工艺能有效地回收铂钯 .在铂钯浮选中用丁黄药和丁胺黑药作联合捕收剂 ,用 L 10 1作微细脉石抑制剂 ,选别效果理想 .在给矿品位为 Pt 0 .2 16 g/ t和 Pd 0 .6 0 3g/ t时 ,获得精矿品位为 Pt 16 .5 40 g/ t和 Pd 19.5 30 g/ t,回收率为Pt4 1.6 4%和 Pd2 3.37% .

Based on the mineral characteristics of the flotation tailings of Pt\|Pd ore in Jinbaoshan Mine, a magnetic separation\|grinding\|flotation process was used to effectively recovery Pt and Pd. In the flotation of Pt and Pd, butyl xanthate and butylamine dithiophosphate were used together as a combined collector and L101 was used as a depressor to micro\|grained gangue, with satisfactory results. When the feed contained 0\^216 g/t Pt and 0\^603 g/t Pd, the resultant concentrate contained 16\^540 g/t Pt and 19\^530 g/t Pd, the recovery of Pt and Pd was 41\^64% and 23\^37%,resp..
