Mining Engineering, EPCM & Equipment OEMs

Engineering, procurement and construction management (EPCM) contractors and original equipment manufacturers (OEMs) are the firms that design, build and equip mining operations worldwide. EPCM contractors provide project management, detailed engineering, procurement management and construction oversight for mine concentrators, hydrometallurgical plants and smelters. Equipment OEMs supply the haul trucks, drills, crushers, mills and flotation cells that make up the physical mining process. This directory lists the principal firms across both categories.
