Postdoctoral Researcher in Autogenous Grinding and Phosphate Ore Valorization

About the role

GSMI is seeking a Postdoctoral Researcher for a 12-month multidisciplinary project on the sustainable valorization of phosphate-rich mining waste through autogenous grinding, a low-energy method for liberating indurated phosphates stored in mining waste deposits (MATs). The project combines mineralogical and mechanical characterization, pilot-scale testing and process simulation to optimize grinding performance and resource recovery, and fits into circular economy goals for the Moroccan phosphate mining sector.

Key responsibilities

• Conduct a detailed literature review on autogenous grinding and phosphate-rich mining waste.
• Design and carry out mechanical, mineralogical and rheological characterizations of MATs.
• Select and size an autogenous mill for pilot testing and lead lab-scale autogenous grinding trials based on experimental design.
• Contribute to numerical modeling of beneficiation circuits (e.g. with USIMPAC or similar software).
• Analyze and report the results of simulations and pilot tests, and draft technical reports and scientific publications.
• Coordinate with internal researchers, external labs and industrial partners.

Required profile

• PhD in Mineral Processing, Mining Engineering, Georesources Engineering or a related field.
• Proven experience in ore characterization techniques (mechanical, mineralogical, physical).
• Solid knowledge of comminution technologies and mineral beneficiation processes.
• Strong analytical and problem-solving skills, and excellent written and oral communication in English or French.
• Ability to work independently and within a multidisciplinary team.

Preferred qualifications

• Experience in grinding technology.
• Familiarity with process simulation software such as USIMPAC, MODSIM or METSIM.
• Prior collaboration with industrial partners.
• Good knowledge of phosphate ores and the North African mineral context.

To apply, candidates must submit a cover letter, detailed CV, list of publications, copies of diplomas and at least two professional references.
