Pit Optimization – How I View It

Jun 03, 2015 · One of the first steps in open pit mine design is the completion of a pit optimization analysis. Pit optimisation is used to define the most profitable pit shell (or nested pit shells) for a given set of economic parameters. The economic parameters generally include the metal prices, process recoveries, and operating costs.

capital cost is estimated at $286,645,232, annual fixed cost at $46,759,088 and processing cost of US$ 7.59 / ton. The planned pit design incorporates 15.2 m high and 50 m wide

(PDF) COST ESTIMATION FOR OPEN PIT MINES: TACKLING COST ...

COST ESTIMATION FOR OPEN PIT MINES: TACKLING COST UNCERTAINTIES. In this paper, cost uncertainty is considered as cost of under production, and cost of over production. The cost uncertainty model is developed using the real option techniques. The proposed cost model is applied through an example case study of the hypothetical copper mines.

Amankwah, H. (2011). Mathematical Optimization Models and Methods for Open-Pit Mining. Doctoral dissertation. ISBN 978-91-7393-073-4. ISSN 0345-7524. Open-pit mining is an operation in which blocks from the ground are dug to extract the ore contained in them, and in this process a deeper and deeper pit is formed until the min-ing operation ends.

Ecological Costs Internalization in Ultimate Pit Optimization

Dec 01, 2014 · The tradition way of open pit mine design just takes the operating and capital costs into account while the ecological costs of mining to ecological environment is not a concern at all. For this concept, based on the mine ecological footprint and eco-cost models which have been built by author, the ecological cost allocation models which take mining, stripping and …
