ROLE SUMMARYThe Process Chemist will run bench-scale hydrometallurgy experiments to recover critical minerals and rare earth elements from black mass and sintered magnets. Working under the R&D; Lead, the role turns experiment plans into reliable data on recovery, purity and process conditions, which feeds into scale-up.

KEY RESPONSIBILITIES● Leaching trials: Conduct acid and reductive leaching experiments on black mass and magnet feeds, varying acid strength, temperature, solid-liquid ratio, time and reductant dosage.
● Purification: Run impurity removal steps such as pH-controlled precipitation, cementation and filtration.
● Solvent extraction: Perform solvent extraction,



scrubbing and stripping trials, including shake-out tests, isotherms and multi-stage simulations.
● Product recovery: Carry out precipitation and crystallisation of metal salts / oxides (e.g. Li, Co, Ni, Mn compounds and REE oxalates / oxides) and evaluate product quality.
● Parameter studies: Execute experiment plans (including DoE), study kinetics and generate data for recovery, selectivity and reagent consumption.
● Records: Maintain detailed lab notebooks, trial logs and mass balances, and prepare summary reports for the R&D; Lead.
● Scale-up support: Support preparation of data for the pilot plant team when needed.
● Lab upkeep & safety: Manage reagent preparation, set-ups (reactors, filtration, SX equipment) and protected handling and disposal of acids, solvents and residues.

QUALIFICATIONS● M.Sc in Chemistry (Inorganic / Physical / Industrial), OR B.Tech / M.Tech in Chemical Engineering or Metallurgy.

EXPERIENCE● 2–5 year
