| Abstract: | Some main calcutating methods to ditermining cut-off grade were discussed by tbe way of this the drawing incoming and outgoing balance. The causes of the lower results to calculate cut-off grade according to the averaga recovery of mieral procesing was analyzed. The calculating formula of cut-off grade was proposed by the average recovery or the recovery corresponding to cut-off grade.While there are some difficulties in this calculation. The calculating method to ditermining cut-off grade according to the tailing grade was given out. This method is recommened because it is simple,convenient and dependable. |

| Keywords: | This time drawing Incoming and outgoing balance method Cut-off grade Recovery of mineral processing Tailing grade |
