| Abstract: |
| The iron ore contain Mo 0.954%, Pb 2.67%, Ag 29.07g/t, Fe 26.53%, SiO2 38.52%.Based on the technological mineralogy of ore and the research, using the mineral processing technology, a grinding to -0.074mm employed 83.4%, two times of roughing, the second time of roughing yield directly qualified molybdenum concen -trates; Three times of scavenging; Combined scavenging concentrates and the first roughing concentrates, the two selected outputs another molybdenum concentrates. The closed tests obtained the technical index, concentrate yield of 10.71%, molybde -num grade 8.09%, lead grade 19.27%, molybdenum recovery rate 90.97%, lead recovery rate 77.59%, containing silver 195.6g/t. |
