Director & Principal Process Engineer

Oliver Kloiber-Deane BEng(Chem), MSc(Math)


Since starting in the minerals industry as a Process Engineer in 2002 Oliver has obtained experience across an array of industry facets:

  • Design, construction, commissioning and operation of an oxidative leach hydrometallurgical demonstration plant producing full-size copper and nickel LME cathode and a cobalt carbonate precipitate (2002 - 2005)
  • Project manager, principal process engineer and senior metallurgist roles in numerous fully integrated hydrometallurgical pilot plants, covering all unit operations between concentrate thickener underflow and final cathode (2003 - present)
  • Design and implementation of SCADA and metallurgical accounting systems for pilot operation: bringing data together from multiple and disparate sources to generate daily metallurgical accounts and reports (2010 - present)
  • Design, management, operation and reporting of metallurgical testwork programs (2009 - present)
  • Base and precious metal hydrometallurgical flow-sheet development and modelling in METSM® and ITHACA® (2004 - present).

Oliver's main area of operational experience is in oxidative leaching of sulphide concentrates for recovery of base and precious metals, with significant experience also in associated solid-liquid separation, precipitation, solvent extraction and electrowinning operations. Some process experience in flotation, high-pressure acid leaching, gold and silver recovery, alkaline sulphide leaching, ammonia leaching, ammonia stripping/recovery and effluent treatment operations has also been gathered.

Since 2006 Oliver has worked as a process engineer for various engineering consultancies as well as supplied his process modelling service through Element Resource Consulting.

Oliver has a Bachelor degree in Chemical Engineering from RMIT University (Melbourne, Australia) and a Master degree in Mathematical Science (Modelling and Computational Mathematics) from QUT (Brisbane, Australia). Oliver is also a member of Engineers Australia.

Jessica Kloiber-Deane BSc(Earth Sc)(1st Class Hons)


Jessica began her career as an undergraduate geologist mapping underground copper and zinc ores at Mount Isa Mines in Queensland before transitioning to exploration and mine geologist roles in the Western Australian iron-ore industry at Robe River Mining and Pilbara Iron.

Jessica now splits her time between senior project management for a translation agency and administration and marketing for Element Resource Consulting.

Further Info

The degree of fidelity to reality required of a model should be judged carefully: the solution must be sufficiently accurate to correctly answer the questions posed without wasting time modelling features that have no significant impact on outcomes. For this reason process models built over the life of a project typically range from very simple at the desktop-study stage to highly detailed at the engineering and commissioning stages. Models may then continue to be evolved during plant operation in order to optimise the process for new feed-stock, de-bottleneck for greater throughput, etc.

Close communication with our client and adherence to client specification documents (process design criteria, process flow diagrams, control philosophy, etc) is our standard approach. Client input is typically required on a range of issues throughout a modelling project. For example process modelling during a flow-sheet development stage often uncovers issues in the process design that had not yet been considered by the design team - commonly water balance, impurities build-up and related effluent treatment issues for hydrometallurgical flow-sheets.

We also find that a period of time spent in the same physical location as the client in the early stages of modelling a complex flowsheet can speed up delivery by removing communication delays.

Our typical deliverable is an electronic file containing neatly formatted process simulation output data and a report that illustrates the model flow-sheet; demonstrates the model's fidelity to the client's design criteria; lists and justifies any assumptions made; and provides a brief analysis of outcomes. If necessary a section will also illustrate any process risks and sensitivities that may have been uncovered. We are also happy to supply the live model files which thereafter allows the client to view and modify the models themselves.
