| Abstract: | To study the process of ore blending in phosphate stockyard,a multi-objective mathematical model was constructed.The ore quality requirements for mineral processing were selected as the objective function of the multi-objective mathematical model,meanwhile,maximum utilization of the lower quality ore was ensured.Resource and decision variables were constrained by the constrained function.Then multi-objective solving function of the Matlab optimization toolbox was used to solve an example and the multi-objective optimization model of ore blending.And the calculation result was compared with the actual ore blending result.The results show that the process of ore blending is described simply,intuitively and completely by the multi-objective mathematical model;the multi-objective solving method of the Matlab optimization toolbox is simple and effective for solving the multi-objective mathematical model of ore blending. |
| Keywords: | ore blending in stockyard multi-objective optimization mathematical model of ore blending |
