Colorado Molybdenum Mine – In-Pit Dewatering EI&C Design

At a high-altitude molybdenum mine in Colorado, dewatering the main pit meant getting power and controls down the pit wall to a series of skid-mounted pump stations. CEI produced the construction-ready electrical, instrumentation, and controls design: an overhead pole line carrying power and aerial fiber from the pit rim to the floor, pole-mounted transformers feeding…

Nevada Copper Mine – Power Study & Arc-Flash Analysis

A copper mine in Nevada needed a current picture of its mine-area electrical distribution to operate and maintain it safely. Working from the mine’s one-line diagrams and on-site field data collection, CEI performed a power-system study across the mine’s distribution circuits. The study evaluated the distribution and delivered an arc-flash hazard analysis, giving crews accurate…

Nevada Gold Mine – Feasibility Study (Electrical & I&C)

For a planned new gold concentrator at a gold mine in northern Nevada, CEI provided the electrical and instrumentation scope of a feasibility study. To feasibility-level rigor, CEI developed the electrical design criteria, load and equipment lists, high- and medium-voltage single-line diagrams, cable list, and E&I material take-offs, along with package specifications and CapEx/OpEx pricing…
