Description
Positions:
- Chemist - Solvent Extraction & Electrowinning (SX-EW)
- Conduct chemical analyses of copper-bearing solutions, organic solvents, and electrolytes.
- Monitor and control key parameters in the SX-EW process, such as pH, redox potential, and copper concentrations.
- Provide recommendations to optimize copper extraction and ensure efficient electrowinning, maximizing copper recovery and purity.
- Perform routine sampling and testing of leach solutions, organic and aqueous phases, and electrolyte for copper concentration, impurities, and acid content.
- Use analytical techniques such as Atomic Absorption Spectroscopy (AAS), Inductively Coupled Plasma (ICP), titrations, and other wet chemistry methods to ensure product quality and process efficiency.
- Prepare and interpret data reports to support process control decisions. ncy.
3. Troubleshooting and Problem Solving:
Identify process deviations or inefficiencies and provide real-time recommendations for corrective actions.
- Collaborate with process engineers to investigate root causes of process issues, such as organic phase separation problems, chemical degradation, or low copper cathode quality.
- Develop chemical treatment programs to manage impurities in the SX-EW circuit (e.g., iron, manganese, or chloride management).
4. Chemical Inventory and Management:
- Manage the supply and usage of reagents such as solvents, extractants, acid, and anti-scalants.
- Ensure safe handling, storage, and disposal of chemicals in compliance with environmental and safety regulations.
- Optimize reagent consumption to reduce operational costs without compromising process efficiency.
- Work with operations and engineering teams to evaluate new extractants, solvents, and electrolytes for potential process improvements.
- Develop new procedures for enhanced copper recovery, reduced organic losses, and longer electrowinning cell life.
- Participate in process scaling and piloting new technologies for continuous improvement in copper cathode production.
6. Safety and Compliance:
- Follow all company safety standards and ensure safe laboratory and plant practices.
- Support environmental compliance by monitoring effluent quality and ensuring adherence to regulatory guidelines related to chemical usage and disposal.
7. Reporting:
- Prepare daily, weekly, and monthly reports on chemical analysis, process performance, and reagent usage.
- Document any process changes, troubleshooting actions, and improvements implemented.
Requirements
- Bachelor’s degree in chemistry, Chemical Engineering, or related field.
- 2+ years of experience in a chemical processing or metallurgical environment, preferably in solvent extraction and electrowinning.
- Strong knowledge of copper hydrometallurgy and SX-EW processes.
- Proficiency with laboratory equipment and analytical techniques such as ICP, AAS, and titrations.
- Familiarity with industrial solvent extraction reagents, electrolyte composition, and impurity control.
- Strong analytical and problem-solving skills.
- Ability to work effectively both independently and within a multidisciplinary team.
- Excellent written and verbal communication skills. Preferred Skills:
- Experience with copper production and electrowinning technologies.
- Knowledge of process control systems in hydrometallurgical operations.
- Understanding of reagent management and chemical cost control.
- Familiarity with safety standards and environmental regulations in metallurgical operations.
