Zusammenfassung

tozero.solutions is seeking an Hydrometallurgy Intern to support process development and R&D in leaching, kinetics, and mass transfer for recovering critical battery materials. You will work with engineers to analyze reaction mechanisms, optimize parameters, and assess process efficiencies through experiments and simulations.

You will design and perform hydrometallurgical experiments, analyze data with DOE and regression tools, and contribute to scaling studies from lab to pilot scale.

Qualifikationen

• Pursuing or completed a Master’s degree in Chemical Engineering, Metallurgical Engineering, Materials Science, or related field.
• Strong knowledge of reaction kinetics, diffusion principles, and hydrometallurgical processes.
• Proficiency with data analysis tools and DOE design.
• Hands-on laboratory experience in chemical or metallurgical processing.
• Familiarity with Minitab or statistical software for experimental design and optimization.
• Fluent in English; German language skills are a plus.

Aufgaben

• Assist in designing hydrometallurgical leaching and separation experiments with a focus on kinetics and diffusion.
• Perform data analysis (kinetic modeling, reaction rate, diffusion studies) for process optimization.
• Contribute to scaling studies and linking lab results to pilot-scale implementation.
• Support evaluation of mass transfer, reaction mechanisms, and process control factors.
• Document findings and contribute to technical reports and presentations.
• Use simulation software for process modeling and apply DOE methods for optimization.
