通过对大厂１００号特富矿石的选矿试验研究，从小型试验四个流程中优选出磁─浮─重和磁─重─浮─重两类原则流程进行扩大试验，均获得较好的选别指标。巴里选矿厂和长坡选矿厂采用磁─浮─重流程，硫化矿浮选分别采用两段混浮分离和优先混浮分离无氰工艺，生产实践表明，磁─浮─重优先混浮分离工艺具有流程简单、分选指标好的特点。
Through the beneficiation test research on Dafu 100 Tefu ore, we choose two principles of Magnetism-Float-weight and Mag-weight-Float-weight principle from the four small-scale experiments, Do not target. Barry beneficiation plant and the long slope beneficiation plant using magnetic ─ ─ ─ ─ heavy flow, sulfide ore flotation were separated by two-stage mixed floatation and preferential mixing floatation cyanide-free process, production practice shows that the magnetic ─ floating ─ heavy priority floatation separation process With a simple process, sorting indicators and good features.
