摘要
锡铁山铅锌矿选矿车间有Ⅰ、Ⅱ、Ⅲ、Ⅳ共4个系列生产线,生产流程复杂,且各个流程所用药剂及pH值的调节均不相同。生产中为合理控制矿浆pH值,通过单因素试验,考察了不同阶段浮选pH值对铅锌精矿品位及回收率的影响。考察结果表明:在一定的pH值范围内,铅锌矿才能有较好的可浮性,高于或低于该范围,对铅锌矿的可浮性有较大影响;同时pH值还影响浮选药剂活性,浮选药剂需要在特定的pH值环境下才能稳定存在,锡铁山铅锌矿选矿车间Ⅰ、Ⅱ、Ⅲ系列采用的是低碱浮选工艺流程,主要回收铅、锌、硫;Ⅳ系列采用的是高碱浮选工艺流程,主要回收铅、锌。
Xitieshan lead-zinc mine mineral processing workshop has four series production lines,that is Ⅰ,Ⅱ,Ⅲ,Ⅳ,production process is complex,not only reagent used but also pH adjust value are different. To reasonably control pulp pH,via single factor tests,influence of flotation pH on lead concentrate and zinc concentrate grade and recovery about various stages was investigated. Investigated results showed that,lead-zinc ore has good floatability in a certain pH range,higher or lower than this range,floatability of lead-zinc ore will great influenced. Also,pH value can influence activity of flotation reagents,flotation reagents needs certain pH to stable existence. Xitieshan lead-zinc mine mineral processing workshop production lines Ⅰ,Ⅱ,Ⅲ uses low alkaline flotation process,mainly recovery lead,zinc,sulfur. Ⅳ series uses high alkaline flotation process,mainly recovery lead,zinc.
