PhD candidate/researcher (f/m/d): Developing new concepts for the efficient extraction of critical metals from an Fe-Zn-(Ag)-(Cu) skarn deposit, Kalimantan, Indonesia

As member of the Helmholtz Association of German Research Centers, the HZDR employs about 1,400 people. The Center's focus is on interdisciplinary research in the areas energy, health and matter.

The Department of Analytics is looking for a PhD candidate/researcher (f/m/d) interested in developing new concepts for exploration and the efficient extraction of critical metals from an Fe Zn-(Ag)-(Cu) skarn deposit, Indonesia. The position will start on 01 April 2021, or as soon as possible thereafter, and will run for 3 years and will be remunerated according to grade E13 of the German Collective Wage Agreement for the Civil Service (TVÖD), commensurate with professional experience. In the first year, this will be a 50% position, with the possibility to increase to 75% in the second year, and 100% in the third year.

Scope of your job

This position is part of a larger international consortium project financed by the German Federal Ministry of Education and Research (BMBF) and coordinated by the Helmholtz-Institute Freiberg for Resource Technology (Helmholtz-Center Dresden-Rossendorf). The goal of this project is to investigate the mineralogy and geochemistry of Indonesian ore deposits (Fe-Ni-laterite, polymetallic skarns, orthomagmatic Cu-Ni-PGE) in order to improve the exploration and extraction efficiency.Your main task will be to conduct a detailed geometallurgical sampling and characterization campaign on a polymetallic skarn, Kalimantan, indonesia, integrate the collected data, and use it to develop new concepts for the beneficiation and exploration of critical metal-rich ores. In the final stages of the project, these concepts will be tested by targeted processing tests and research drillings.


  • Planning and conducting a sampling campaign to collect representative samples from the deposit

  • Sample characterization by a combination of different methods, including: whole rock geochemistry, optical microscopy, XRD, H-XRF, MLA/QEMScan, EPMA and LA-ICP-MS

  • Data evaluation and integration

  • Development of new exploration and beneficiation concepts for the deposit using the collected data set

  • Planning and supervision of research drillings and minerals processing test work to verify the developed concepts


  • MSc Degree in economic geology or a closely related field

  • Proficiency in relevant analytical methods (Raman spectroscopy, MLA/QEMScan, EPMA, LA-ICP-MS)

  • Willingness and physical fitness to do fieldwork in a tropical climate

  • Strong motivation to work in a collaborative research environment

  • Excellent communication skills in English in a professional context (presentation of research results at scientific meetings, writing of manuscripts, discussions with colleagues)

We offer:

  • A vibrant research community in an open, diverse, and international work environment
  • Scientific excellence and high-quality training, coaching, and mentoring programs
  • Broad national and international scientific networks
  • Comprehensive benefits package (30 vacation days per year, company pension plan (VBL)
  • Salary and social benefits in conformity with the provisions of the Collective Agreement TVöD-Bund
  • A good work/life balance for which we offer assistance in the form of:
    • possibility to work part-time

    • flexible working hours

    • in-house health management
