FINDING ADDED VALUE AT NEWMONT THROUGH LARGE-SCALE MINING SEQUENCE, CUTOFF GRADE AND PROCESS OPTIMIZATION USING MIXED INTEGER LINEAR PROGRAMMING

摘要

Through the systematic application of mine schedule optimization tools Newmont is identifying added value at its operations. The current state-of-the-art tools, however, lack the specific features needed at its more complex project's to optimize infrastructure size, mining and/or processing rates and cutoff grades. Ultimately the objective of these tools is to assess the optimal scale of a project and provide operating guidance for its mines.
