Gruminex services consist of providing development of engineering and project management for the mining industry, covering the multidisciplinary engineering, such as Civil Engineering, Mechanical Engineering, Electrical Engineering, Instrumentation and Automation of those processes focused to the construction and/or upgrading of such areas.
Each discipline is applied in the different stages of the mining processes, in accordance with the client´s needs. Such stages of the mining processes include:

  • Extraction
  • Transportation
  • Crushing
  • Material Conveying
  • Milling
  • Floating, lixiviation, solvent extraction, etc. (Depending on the Process)
  • Thickening
  • Filtration
  • Tailings Dam



Engineering work is carried out in the main office of Gruminex by a multidisciplinary team of specialized, trained and experienced engineers, applying technical resources, equipment and software, such as

“Permanent and mobile computer equipment, Special programs for Information Analysis and Processing, and Specific Trainin”.

Gruminex provides project Supervision and Management services primarily for Mineral Processing plants, implementing a General Work Program and an adequate Cost Control project, pursuant to the client´s needs, obtaining feedback from the different areas involved in the Construction and from the client himself.
