In the practice of production, Xinhai usually adopts bulk flotation process that floats copper-molybdenum bulk concentrate firstly then separates copper-molybdenum. What's more, single molybdenum ore and copper-molybdenum ore have low hardness, they are easy to become sliming in the grinding process, so Xinhai often uses stage grinding+stage ...

A comparison of the amount of molybdenum recovered in the final concentrate with that of the rougher concentrate shows an 8.39% reduction in metal recovery. Considering the circuit shown in Fig. 1, as well as grade values, are shown in Table 1, molybdenum content increased from 0.86% to 48.70% after 8 stages of cleaner flotation.
