通过对复杂难选的大厂锡石多金属硫化矿尾矿的矿石性质的分析，提出了采用先进的选矿工艺流程和先进技术，特别是合理地利用好分级技术，能实现在流程的前段大量丢尾，并为微细粒锡石的重选回收创造良好的分选条件，是成功回收大厂矿区低品位复杂难选锡石多金属硫化矿尾矿的关键。%Based on the complex nature of refractory ore cassiterite Dachang polymetallic sulfide ore tailings analysis, proposed the use of advanced beneficiation process and advanced technology, especially the use of reasonably good classification technology, to achieve in the process lost a lot of front end, and create good conditions for micro-fine sorting cassiterite re-election recovery, is the key to successful recovery of low-grade cassiterite mining giant polymetallic sulfide ore tailings complex and difficult choice.
