Our Metallurgy Team is responsible for safely processing and recovering precious metals from the materials that come through

Working across gold and silver, the team manages specialist melting, casting and recovery processes to turn mixed materials into consistent precious-metal bars while protecting material value, maintaining accurate records and operating to high safety standards.

It’s a technical environment where precision matters. The team works closely together to maintain safe, reliable operations, improve recovery and share specialist knowledge as our capabilities continue to develop.

As a Senior Smelter, you’ll bring specialist knowledge and experience to some of our most complex precious-metal processing activity.

You’ll operate and oversee melting and casting processes across gold and silver, working carefully with high-value materials to achieve consistent output, protect metal recovery and maintain accurate records throughout each melt.

Alongside your own technical work, you’ll support the development of other Smelters, share knowledge and help maintain strong standards around safety, equipment care and ways of working.

Working closely with the Metal Melting Director and the wider Metallurgy Team, you’ll also use your experience to identify opportunities to improve processes, reduce material loss and strengthen the reliability of our foundry operation.

• Complex melt cycles are completed safely, consistently and in line with agreed processing and recovery standards.
• Precious-metal recovery is carefully managed, with material loss minimised throughout melting, casting and recovery processes.
• Raw material weights, cast bar weights, assay samples and melt records are complete and accurate.
• Furnaces, crucibles, particulate collection systems and other foundry equipment are maintained to support safe and reliable operation.
• Safety procedures, PPE requirements and local exhaust ventilation controls are consistently followed and reinforced across the working environment.
• Gold and silver bars are cast consistently and move through the next stage of the process with clear and accurate records.
• Opportunities to improve yield, quality, safety or process efficiency are identified and shared with the wider team.
• Mentor junior smelters and collaborate with specialists and leaders to maintain safe and reliable foundry output.

• Prepare, load, and operate induction and gas-fired melting furnaces to process complex scrap, grain, and high-value feedstock.
• Monitor heat cycles, adjust furnace controls, and apply specialised fluxing agents to separate impurities and manage slag effectively.
• Apply appropriate fluxing processes to separate impurities, manage slag and support precious-metal recovery.
• Use your technical judgement to identify issues during processing and take appropriate action or escape where specialist support is required.

• Skim molten metal surfaces safely and pour liquid metal into preheated molds to produce high-grade bars and ingots.
• Weigh incoming material and finished bars accurately and maintain clear records throughout the process.
• Collect assay samples correctly so material can move through testing and subsequent processing with reliable information.
• Maintain complete and accurate melt logs so material…
