Determination of optimal cut-off grade policy to optimize NPV using a new approach with optimization factor
One of the most difficult problems in mining operation is how to determine optimum cut-off grades of ores at different periods over the lifespan of the mine that will maximize the net present value (NPV) of the mine. Maximizing the NPV of a mining operation, subject to different constraints is a nonlinear programming problem. Cut-off grade optimization is used to arrive at an operating strategy...
متن کاملApplication of Single Objective Genetic Algorithm to Optimize Heat Transfer Enhancement from a Flat Plate
The optimal shape of a two dimensional turbulator above an isothermal flat plate is found by using numerical simulation. The turbulent boundary layer over the flat plate was disrupted at various situations by inserting a quadrilateral bar where the boundary layer thickness kept more than three times greater than the insert\'s height. As a result, the overall heat transfer coefficient of the wal...
متن کاملCut-off Grade Optimization for Maximizing the Output Rate
In the open-pit mining, one of the first decisions that must be made in production planning stage, after completing the design of final pit limits, is determining of the processing plant cut-off grade. Since this grade has an essential effect on operations, choosing the optimum cut-off grade is of considerable importance. Different goals may be used for determining optimum cut-off grade. One of...
متن کاملClassifications and Properties of Materials for Chairside Computer-Aided Design/Computer-Aided Manufacturing Dentistry: A Review
Background and Aim: Chairside computer-aided design/computer-aided manufacturing (CAD/CAM) systems have become considerably more accurate, reliable, efficient, fast, and prevalent since 1985 when CEREC was introduced. The inceptive restorative material option for chairside CAD/CAM restorations was limited to ceramic blocks. Today, restorative material options have been multiplied and include me...
متن کاملAn Optimum Algorithm for Cut-off Grade Calculation Using Multistage Stochastic Programming
Cut-off grade is one of the very important technical and economic parameters, which affects the economic and social efficiency in a mine enterprise. It is also the basis of the deposits technical economy evaluation, feasibility study, mining planning and design and the foundation of the decision-making in mining investment. Thereby, cut-off grade optimization is one of the core contents and the...
