Arsenic/Minor Element Controls in Metallurgical Plants
Ten years since the Arsenic Metallurgy Symposium held in Vancouver during COM 2014 it is timely and pertinent to have a new meeting that brings together experts from mineral separation and hydro/pyro extraction to by-product recovery and environmental stabilization. Such meeting will be highly valuable in showcasing both research and industrial advances as efforts intensify for securing raw material supply in a sustainable and clean processing direction. Minor elements like arsenic but also antimony, selenium, tellurium, and bismuth must be controlled not only in terms of effective environmental removal and stabilization but also in terms of by-product recovery given the high demand of some of them in several new advanced applications. Solutions to the challenges these elements impose can only be advanced via synergies of different technical approaches from mineralogy and mineral separations to their deportment during metallurgical processing (hydro/pyro), treatment and stabilization that consider process chemistry (speciation, thermodynamics, kinetics, modeling), economic factors and long-term environmental compliance. The symposium will cover different non-ferrous metal industries from mineral processing, smelting, roasting and acid plants to leaching, purification and electrorefining operations in addition to wastewater/effluent and residue/tailings treatment and disposal including minor element recovery.
Symposium is supported by the Hydrometallurgy and Pyrometallurgy sections of MetSoc.

Corrosion and Environmental Degradation of Materials
Environmental degradation and corrosion can severely limit the durability and reliability of structural and functional materials, which include not only metallic materials but also ceramics, polymers, and composites. Environmental deterioration of engineering materials can be complicated, often dependent on material, chemical, and mechanical variables. This symposium aims to bring together scientists, engineers and technologists from academia and industry to discuss recent advances in theory, computational modeling and experiments related to corrosion and degradation of engineering materials and its control. General topics of interest interest include, but are not limited to, general and localized corrosion, metallurgical influences, chemical-mechanical interactions, mechanistic studies, corrosion control, corrosion sensing, and advanced characterization of corrosion phenomena. Applications of particular interest include, but are not limited to energy and power generation, fuel transportation, manufacturing and biomass/chemical processing.
- General and localized corrosion
- Environmentally induced cracking
- High temperature oxidation
- Surface treatments for corrosion prevention
- Sustainable corrosion control technology
The audience of this symposium will be academic and industrial researchers working on the topic of corrosion and degradation of materials. The relevant industry sectors are aerospace, automotive, navy, oil, biomass and nuclear.

Extractive Metallurgy from Conception to Operation: Experimentation, Simulation, Pilot and Ramp-up
This symposium gathers academic and industry experts in extractive metallurgy, and focuses on the engineering pipeline that enables high energy, high temperature and/or high intensity processes, such as traditional pyrometallurgical processes, plasma processes, novel approaches to comminution and breakage, etc. applied to mineral and/or recycled feeds. Both ferrous and nonferrous extractive metallurgy will be featured.
A foundational understanding of a critical unit operation can be established with bench-scale experiments, often within an academic setting, but must be subject to multi-stage engineering projects to be integrated into the industrial scale, benefitting from computational tools and specialized simulation techniques. Moreover, existing metallurgical facilities require reengineering projects and continuous improvement to remain economically competitive, which also depend on experimentation and simulation, and on integrative engineering methodologies.
The symposium will be an exchange of perspectives, including reports on academic and industrial experiments, usage and development of computational tools, and general engineering perspectives on extractive metallurgy.
Specific themes include, but are not limited to:
- Case studies of successful and unsuccessful engineering projects
- Challenges in running high-energy experiments in the academic setting
- Hybridization of mineral processing and extractive metallurgy
- Hybridization of extractive metallurgy and recycling
- Current and future trends in extractive metallurgy

25th International Biohydrometallurgy Symposium (IBS 2024)
The International Biohydrometallurgy Symposium is a global forum that brings together representatives to share knowledge on advancements on science and technology in the field of mining biotechnology and discuss innovative solutions and best practice approaches in the industry.
Drawing from the expertise in biotechnology, chemistry, mineralogy, and engineering, mining biotechnology can benefit the resource sector by enabling the extraction of value from low-grade minerals and wastes streams, providing tools for minerals exploration and environmental monitoring, and mitigating harmful environmental impacts.
- Bioleaching of metals from low-grade ores and concentrates
- Biomining engineering applications (e.g. in situ, dump, heap, vat, reactor)
- Biomining of wastes and circular economy
- Biotreatment of mining effluents for water recovery and cleanup

WALSIM X: Water, Air, Land Sustainability Issues in Mining and Metal Extraction
This year’s WALSIM symposium will be the tenth symposium on Water, Air, Land Sustainability Issues in Mining, Mineral Processing and Metal Extraction. The theme of the symposium will be focused on the technical advances being made by a wide variety of industries to promote more efficient and sustainable processes. In this regard, five major topics of relevance to the mining, minerals and metals industries are proposed as follows: towards zero waste, greenhouse gas reduction, water conservation, non-conventional resources and supply issues. Each of these topics is described in more detail below.
Towards Zero Waste: Mining, mineral processing and metal extraction can be integrated and this can lead to a circular economy that promotes the minimization of waste. Waste streams can in fact be considered as secondary resources of either valuable minerals or metals.
Greenhouse Gas Reduction: The various industries are trying to minimize greenhouse gas reductions. Papers are invited on the quantitative reduction of greenhouse gases, in particular carbon dioxide, for the mining. minerals and metals extraction industries.
Water Conservation: The conservation of water is of particular concern for the metal extraction industries and also for the environment. The water composition and its effects on the process, for example fresh water versus seawater, is an important consideration in mineral concentration processes.
Non-Conventional Resources: Landfills and other resources are being considered for metal extraction and this has become known as urban mining. Also, landfills release leachates from which metals could be recovered. Other non-conventional resources include deep sea polymetallic nodules.
Supply Issues: The supply of materials is becoming an issue due to a number of factors including geopolitics and supply-chain challenges. From obtaining a permit to start a mine to shipping raw materials around the world, the supply of materials is becoming a significant issue.
Papers concerning other relevant sustainability subjects, which do not fully align with the proposed symposium topics will also be considered. If a group of papers are submitted on a particular topic then a separate session can be added.
This symposium should be of interest to people in industry, academia, government, and research.
