Introduction
Mintek has an exciting opportunity for Engineers/Scientists who will undertake commercial commissions and research projects in the field of percolation leaching (heap leaching) of low-grade ores under the guidance of a Principal Investigator, execute defined research activities with increasing independence.
Job description
KEY PERFORMANCE INDICATORS:
- Execute laboratory, column, and pilot-scale test work for chemical and biological heap leaching systems in line with project scope, timelines, and quality requirements.
- Analyse and interpret experimental data, including microbial performance, mass balances, metal recoveries, leach kinetics, and reagent consumption.
- Display a sound understanding of the inter-related biological and chemical processes in heap leaching systems.
- Prepare clear, accurate, and high-quality technical reports, including participation in meetings and oral presentations to internal and external stakeholders.
- Collaborate within multidisciplinary teams and demonstrate progression towards independent execution of defined research activities and small projects.
- Contribute to ideation, conceptual development, and preparation of research funding proposals, including Science Vote submissions and commercial project proposals.
