Process Flow Test of Grinding and Separation System in Nanfen Concentrator
In order to provide data support for the grinding separation process flow and equipment se-lection,aiming at the problem that the grinding and separation process flow does not match the particle size of the existing treated ore in the production operation of Nanfen concentrator,on the basis of process miner-alogy research,the laboratory grinding and separation process flow test is carried out on the high-pressure roller mill -3 mm wet-polishing concentrate treated by the new grinding and separation system.The test re-sults show that under the condition of the first grinding fineness of -74 μm 64.70% and the second grinding fineness of -43 μm 78.21%,the low intensity magnetic concentrate with yield of 33.63%,TFe content of 68.02%,mFe content of 66.42%,TFe recovery of 79.41% and mFe recovery of 98.23% is obtained by stage grinding-low intensity magnetic separation process,and satisfactory test indexes are obtained.
