Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

Equipment selection effects economic considerations in openpit design, specifically overburden, waste rock and ore mining costs and cost escalation parameters as a function of plan location and depth. Mining costs are a function of site conditions, operating scale and equipment. The purpose of equipment selection is to select optimum equipment ...

FCX operates seven openpit copper mines in North America — Morenci, Bagdad, Safford, Sierrita and Miami in Arizona, and Chino and Tyrone in New Mexico. Molybdenum concentrate, gold and silver are also produced by certain of FCX's North America copper mines. All of the North America mining operations are wholly owned, except for Morenci.

Optimum pit design plays a major role in all stages of the life of an open pit: at the feasibility study stage when there is a need to produce a wholeoflife pit design; at the operating phase when pits need to be developed to respond to changes in metal prices, costs, ore reserves, and wall slopes; and towards the end of a mine's life where ...

Misery operations will transition from open pit to underground mining in 2018, subject to permitting approvals. The current mine life of Ekati, including the Misery underground and the Jay project, is 2034. Several exploration and project evaluation activities are ongoing, including the Fox Deep project which would extend the life of Ekati to 2042.
