白音诺尔铅锌矿南矿带矿石性质复杂,精矿质量差、回收率低,铅精矿含锌9%左右,锌精矿含铅2%5～2.5%。铅精矿品位63%,回收率84%;锌精矿锌品位46％,回收率82％。针对上述问题在试验室进行多种磨选流程的试验,脱(选)泥碳分支阶段磨选流程和脱(选)泥碳分支浮选部分铅粗精再磨流程都能降低铅、锌精矿中锌、铅互含量,同时能提高铅、锌精矿品位和回收率,这两种脱泥碳流程与目前该矿采用的生产流程(用同一矿样试验指标)相比:铅精矿含锌分别降低1.45％和1.41％,锌精矿含铅分别降低0.63％和0.39％;铅精矿品位分别提高6.23％和1.70％,回收率分别提高4.27％和0.71％;锌精矿品位分别提高4.54％和0.12％,回收率提高2.39％和接近。
The ore quality of Baiyinnuoer Lead-Zinc Mine South Mine is complex with poor quality and low recovery rate. Lead concentrate contains about 9% zinc and zinc concentrate contains 2% 5 ~ 2.5% lead. Lead concentrate grade 63%, recovery 84%; zinc concentrate zinc grade 46%, recovery 82%. In view of the above problems in the laboratory test a variety of milling process, de-election (Mud carbon branch of the milling process and de-election (Mud carbon branch) flotation part of the rough lead regrinding process can reduce lead, zinc concentrate Ore zinc, lead mutual content, while improving lead and zinc concentrate grade and recovery rate, both of the stripping carbon flow and the current production process used in the mine (with the same ore test indicators) compared to: lead concentrate Zinc concentrates decreased 1.45% and 1.41% respectively, while lead contents in zinc concentrates decreased 0.63% and 0.39% respectively. The grade of lead concentrates increased by 6.23% and 1.70% respectively, and the recoveries increased by 4.27% and 0.71% respectively. Increased by 4.54% and 0.12%, the recovery rate increased by 2.39% and close.
