Solution of the problem may involve metallurgical processing of low-grade (7–20%) concentrates and middlings, whose extraction of tungsten and molybdenum in the concentration stage is 93–95%. Development of rational methods for processing this lean raw material would make it possible to increase considerably the yield of metals from ore in ...

4 Summary Processing technology of middlings should be adapted to the mineral and petrographic properties of the processed ore. Therefore, in the case of Polish copper ores, which tend to produce large quantities of difficult to treat middlings, separate processing of these middlings should be preferred.

Consequently, Erdenet PP tailings are composed of three process products: recleaner bulk flotation tailings (tailings I); middling cycle tailings (tailings II); Cu–Mo flotation tailings (tailings III). Structurally, the final concentration cycle is a canonical flow chart of the rougher, recleaner and scavenger flotations.
