Job Description
Job Summary We are seeking a motivated Bio-Process Engineer/Technician to support the development and scale-up of bioleaching processes for the recycling of industrial waste using bacteria or other microorganisms. The roleinvolves conducting laboratory- and pilot-scale experiments, managing process flows to produce pregnant leach solutions, and evaluating key technical parameters to support process optimization and scale-up. Key Responsibilities Design and conduct laboratory-scale experiments on the bioleaching of industrial waste using bacteria or other microorganisms. Prepare, operate, and monitor bioleaching systems (e.g., flasks, bioreactors, leaching columns) under controlled conditions. Handle and manage the overall process flow from feedstock preparation through bioleaching to obtain pregnant leach solutions (PLS). Monitor and analyze critical process parameters such as pH, temperature, redox potential, microbial activity, metal recovery rates, and leaching kinetics. Scale exper...
