Pit Optimization – How I View It

2015-6-3  Pit optimization is used to define the most profitable pit shell (or nested pit shells) for a given set of economic parameters. The economic parameters include the metal prices, process recoveries, and operating costs. Normally when optimization is done, a range of metal prices or revenue factors is used

A wholeness approach to open pit scheduling and

2021-4-15  Assuming an average mining cost of one dollar per ton, the value of just moving material can be worth more than one million dollars per day for large operations. So, if the value of a mine plan can be worth hundreds of millions of dollars, in some cases billions of dollars, it’s easy to argue that mine planners increase fortunes every time the mine plan is improved.
