The effect of grinding circuit efficiency on the grade and recovery of copper and molybdenum concentrates

The efficiency of grinding and flotation process in copper-molybdenum processing circuit, largely affected by performance thickeners hydrocyclones devices. goal this paper is to investigate the effect rate-limiting factors on these devices consequently separation molybdenum circuit. So, a full mineralogical study have been carried out outputs hydrocyclone molybdenite According results, coarse-grained fractions (>50 μm) planar will not necessarily be recovered thickener hydrocyclones. This especially true for when inlet-load rate high, i.e., erroneous discharge particles from overflow hydrocyclone, as well their floatability overflow, can attributed particle shape size. issue harms grade recovery due increase amount circulating load (regrinding) generation fine (<10 hydrocyclone-milling On other hand, almost spherical copper minerals, nonplanar fine-grained particles, are easily removed underflow or settled thickeners. introduction mineral into concentrate vice versa has reduced quality produced undesirable performance.
