Postdoctoral Researcher in Autogenous Grinding and Phosphate Ore Valorization

About the role

GSMI is looking for a Postdoctoral Researcher for a 12-month project on the sustainable use 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, and aims to optimize grinding performance and resource recovery while reducing energy consumption. It fits into broader goals of circular economy and innovation in the Moroccan phosphate mining sector.

Key responsibilities

• Carry out a detailed literature review on autogenous grinding and phosphate-rich mining waste.
• Design and run mechanical, mineralogical and rheological characterizations of MATs.
• Select and size an autogenous mill for pilot testing and lead lab-scale autogenous grinding trials.
• Contribute to numerical modeling of beneficiation circuits (e.g. with USIMPAC or similar software).
• Analyze and report results from 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 ability to work independently and in a multidisciplinary team.
• Excellent written and oral communication in English or French.
• Preferred: experience in grinding technology, familiarity with process simulation software, prior collaboration with industry, and 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.
