Principal Process Engineer – Hydromet and Comminution

About the Project

We are proud to be partnering with Stantec – Energy & Resources to deliver the study for a world-class gold project in South East Asia. This large-scale greenfield development is progressing through its Definitive Feasibility Study (DFS), with early works and execution phases to follow.

The project presents the complexities typical of a major gold and copper development in the region:

  • Comminution and hydrometallurgical processing central to gold and copper recovery
  • Remote location requiring efficient, reliable, and environmentally responsible process solutions
  • Study outcomes that must generate a defensible Class 3 estimate and inform execution readiness
  • Strong interfaces across process, civil, mechanical, electrical, and project controls teams

About the Role

The Process Engineer will support development of the process plant design, with emphasis on comminution and hydrometallurgical methods. Responsibilities include:

  • Preparing study-level process flow diagrams, mass balances, and design criteria
  • Supporting comminution circuit design (crushing and grinding) and integrating test work results into the process flowsheet
  • Contributing to hydrometallurgical circuits including leaching, solution purification, solid-liquid separation, and reagent management
  • Preparing preliminary equipment lists, datasheets, and inputs for Class 3 estimating
  • Assisting with test work programs and integrating laboratory or pilot data into study deliverables
  • Providing input into risk reviews, environmental/regulatory compliance, and water management considerations
  • Coordinating with other engineering disciplines to ensure process interfaces are accurate and constructible

About You

We are seeking a process engineer with:

  • Experience in gold, copper, or similar metals processing, including comminution and hydrometallurgy
  • Knowledge of crushing, grinding, and leaching systems, and how they affect downstream recovery
  • Prior exposure to PFS/DFS deliverables for mining or metallurgical projects
  • Ability to prepare defensible process documentation and design inputs for estimating teams
  • Awareness of regulatory/environmental factors relating to leach reagents, effluents, and tailings
  • Strong collaboration skills across multi-discipline study teams

Roster & Conditions

  • Monday to Friday, based in Perth or Brisbane
  • Hours: 40 per week plus approved overtime
  • Initial 12-month contract, aligned with DFS delivery
