Extraction 2018 Technical Themes and Symposia

Extraction 2018 is the home for several important recurring symposia that examine new developments in foundational extractive metallurgy topics and techniques. It also offers new programming designed to share the latest research and insights on emerging technologies and issues that are shaping the global extractive metallurgy industry. Learn more about each symposium planned for the conference here.

Late News Poster Session: Last Call to Post Your Achievements!

Extraction 2018 is now offering a Late News Poster Session. A limited number of daily poster presentations are available, with different presentations set for Monday, Tuesday, and Wednesday during the conference. This interactive poster session will give individuals not able to make an oral presentation a chance to contribute to the program and network with leaders in the global extractive metallurgy field. Encourage your colleagues and friends to share their work and submit a poster abstract—this opportunity is only available through June 17!

Submit Poster Abstract

The abstract submission site is now closed. Extraction 2018 is no longer accepting abstracts. If you have any questions, please send an e-mail to programming staff. For additional details on Extraction 2018 programming, including a listing of organizers and contact information for each symposia, visit ProgramMaster directly and choose from the listing of symposia titles.


This technical track encompasses all aspects of hydrometallurgy extraction, purification, and recovery of base, critical, rare and precious metals, from both research and industrial application perspectives.

This technical scope of this symposium examines all aspects of sulfide smelting technology, including basic principles, technology, and current operating practice. Authors who are engaged in the analysis, development, and/or operation of high temperature processes that involve the production of metals, metalloids, and alloys through sulfide smelting are encouraged to contribute. Papers that describe innovative methods for achieving impurity separation and removal, by-product recovery, waste minimization, and/or energy efficiency of particular interest, as are those that address important technical, economic, and environmental issues.

New for 2018, the Peter Hayes Symposium is accepting abstracts within the following topic areas:

  • Novel processes, integrated plant designs, process selection and criteria
  • Recycling/environmental impact
  • Experimental fundamentals – determination of phase equilibria, other physicochemical properties
  • Modelling fundamentals – thermodynamic and other physicochemical properties modelling
  • Process fundamentals and reaction kinetics
  • Process/flow modelling

Presentations that offer valuable “lessons learned” are also of interest.

This new programming opportunity encompasses a variety of aspects impacting the flotation of base and precious metals. The focus is on practical applications, with each session designed to convene metallurgists, scientists and operators to discuss and address challenges facing the industry. Of particular interest are presentations examining the following technical themes:

  • Flotation plant design and operational challenges
  • Flotation process mineralogy and geometallurgy
  • New developments in flotation chemistry
  • Recent advances in flotation equipment

Exclusive to Extraction 2018, this one-day symposium will provide the business context for the more meeting’s specific technical symposia and presentations. The intent of the symposium is connect technical and non-technical professionals for discussion of current issues, and development of an improved understanding of each other's fields and challenges. Invited speakers will discuss the metal trading, the impact of impurities on tolling and refining charges, environmental regulations world-wide, protectionism, and an outlook to the future. Anyone in the commodities business, working in either the technical or commercial arena, will benefit from this provocative overview of developing business trends, as well as the networking opportunities with key players in the commodities industry.
