Sunday, March 11, 2018 • 8:30 a.m. to 4:30 p.m.
Phoenix Convention Center
Light Metals Division, Aluminum Committee
Linus Perander, Outotec; Gerrit Vos, APEG-BC (Canada) and CREA-MG (Brazil); Suzette Taylor, Almatis - Global Process Technology Group; Ting-an Zhang, Yves Perret, Alessio Scarsella, Outotec; Peter-Hans ter Weer, TWS Services & Advice - Bauxite & Alumina Consultancy; Markus Graefe, EGA; Siva Soora, Almatis; and Jim Metson, University of Auckland


This one-day short course, targeted at the professional working in the field of alumina production and bauxite processing, complements the regular TMS sessions and will discuss several topical themes in the industry from a more general perspective. The course is expected to also generate discussion and debate and increase awareness and interest in common challenges in the industry. 

Who Attends?

This course is targeted to the following industry sectors: bauxite mining, alumina production, and Bayer process, including alumina from non-bauxitic ores. Industry professionals, e.g. production or technical engineers or senior engineers working in the alumina production sector or with technology providers for the alumina industry, will benefit from this course. Also, academic professionals wanting to gain detailed insight into state-of-the-art practices and technologies employed in the alumina industry and/or attain a deeper understanding on fundamentals in the process or drivers in the industry should attend.

Topical Outline

  1. General Introduction
  2. Metallurgical Grade Alumina—Market Situation and Outlook
  3. Bauxite Mining Supply
  4. Processing of Low-grade and Non-bauxitic Ores
  5. Developments in Digestion and Evaporation
  6. Sustainability in Alumina Refinery Design
  7. Bayer Process Residues
  8. Cost and Energy Reduction in Alumina Refining
  9. Alumina Quality—Does it Matter?
  10. Panel Discussion (all speakers)


Gerrit Vos is a principal consultant and owner of V-ENG UK LLP. He has 27 years of operational experience in open pit and strip mining and more than 12 years of consulting experience performing due-diligence audits—scoping, pre-feasibility, feasibility and related studies. He has experience in bauxite, iron ore, gold, copper, lead-zinc, uranium, phosphate and nickel.

He has working experience in the African and South American tropics, the desert, and the Canadian North, and he has a proven ability to reduce costs and improve productivity. He has Canadian Professional Engineer status and is a Brazilian CREA registered engineer. Vos worked as a mine planning engineer and as overburden stripping supervisor at the Paranam operation of ALCOA in Suriname and audited several bauxite and phosphate operations during his consulting career.

Suzette Taylor is a Global Process Engineer with Almatis—Global Process Technology Group. She has experience in product development, process engineering, production and quality management of aluminum trihydroxides and calcined aluminas. In addition, she has also worked on the coaching of process improvement projects using Six Sigma methodology. She has earned her MS in Chemical Engineering from the University of Arkansas, Fayetteville.

Peter-Hans ter Weer has thirty-five years of international exposure to the bauxite and alumina industry (22 of which was with BHPBilliton), ranging from hands-on experience in plant commissioning, process engineering and production control, to corporate roles in business and technology development and project initiation and evaluation. Since 2004, he has been an independent technical and economic advisor to the bauxite and alumina industry. Weer’s focus is on understanding the key factors affecting the technical and economic success of bauxite and alumina projects.

Markus Gräfe is a soil chemist and mineralogist with 18 years R&D experience in universities, government research organizations and now industry (US, Australia, Ecuador, UAE). His research has focused on mineralogical and contaminant assessments, and sequestration techniques of contaminants for soils and industrial wastes, including bauxite residue, Amazonian, Andean and tropical soils. He is currently the manager for R&D activities in “Bauxite Residue – Agronomy” of the Technology Development and Transfer Department at Emirates Global Aluminium.

Jim Metson is Deputy Vice Chancellor, Research at the University of Auckland. He is a physical chemist with research interests in materials and particularly the science of surfaces. He was a co-founder of the Light Metals Research Centre at Auckland University and founding member of the MacDiarmid Institute for Materials Science and Nanotechnology. He has worked extensively with international industry, particularly in aluminum reduction technology, gas dry-scrubbing, and alumina refining. He was the Program Chair, Alumina and Bauxite, for the TMS 2011 Annual Meeting.
