2022 TMS Annual Meeting & Exhibition: Furnace Tapping 2022: Organized by Joalet Steenkamp; Dean Gregurek; Quinn Reynolds; Gerardo Alvear Flores; Hugo Joubert; Phillip Mackey

Many a metallurgist fell in love with pyrometallurgy after witnessing a smelter being tapped. There is something magical in the combination of light, energy and danger that simultaneously stirs the primal instincts to ‘run for your life’ and ‘go closer and have a look’. But tapping a smelter is not an easy task. Much engineering go into the design of the tap-hole. Due to the aggressive nature of the process, material selection is as important as layout. The design process kicks off with a set of design criteria, which needs to be revised as the results of laboratory, compational fluid dynamics (CFD) and time-and-motion studies become available. The tap-hole life-cyle is taken into account with designers addressing the requirements for installation and operability as well as for maintenance. Matters such as online monitoring of the taphole wear, handling of liquid products, and extraction of fumes are all taken into account. Though tap-hole life can be improved with proper design, a good design can be destroyed with incorrect tapping practices and equipment. Despite the harshness of the tapfloor environment, it requires precision equipment and operating practices. The design and maintenance of the drilling, tapping and plugging equipment and materials plays an equally important role in tap-hole life and tapfloor safety. As does protective equipment. Operators want the tap-hole life to be as long as possible since tap-hole failures is often the cause for a reline—a very expensive exercise in an upcycle when the cost of a new lining is small compared to the loss in production. Managing the maintenance and reline schedule is a challenge with lessons often learned the hard way. The first thing students are taught in pyrometallurgy courses is how to compile a mass and energy balance for a smelter. An accounting mass and energy balance is used not only to schedule furnace taps but also to make process decisions. Process variables measured during or after tapping are important inputs to a workable mass and energy balance. Even though much has been done to make the tapping process as automatic as possible, tapping of smelters cannot be done without labour. Tap floor operators work in harsh environments where safety is of utmost importance. Selection of suitable personnel and intensive training is required. No pyrometallurgical smelter can operate without some form of tapping system. It is the one thing all smelters have in common. A meeting point of science, technology and skill. So let us talk about it.

2020 TMS Annual Meeting & Exhibition: Electrometallurgy 2020: Organized by Antoine Allanore; Michael Free; Georges Houlachi; Hojong Kim; Takanari Ouchi; Shijie Wang

Electrolytic processing is used commercially to recover and/or refine metals including large–scale production of aluminum, copper, magnesium, nickel, and zinc as well as, on a smaller scale, for recovery and refining of gold and silver. There are also exciting opportunities to utilize electrometallurgy in the production of titanium, lead, and other metals. Electrolytic processing of metals faces common challenges that include energy utilization, chemistry, productivity, and safety. To meet the present challenges in commercial electrometallurgy, a variety of technological advances have been made. Similar challenges will be faced in the future, requiring process improvements and innovations. The 3rd International Symposium on Electrometallurgy – building on the success of Orlando 2012 and Quebec City 2016, will bring together industry, consulting engineers and researchers to discuss fundamental research, development, and/or application of innovative aqueous or molten salt electrometallurgical processing technologies for the extraction of metals.

2018 TMS Annual Meeting & Exhibition: Deriving Value from Challenging Waste Streams: Recycling and Sustainability Joint Session: Organized by Elsa Olivetti; John Howarter; Fiseha Tesfaye

For many products, there is a significant mismatch between the technical needs for responsible treatment of secondary and byproduct materials and the ability to achieve economically feasible operations. These feedstocks are generally low value and can be quite complex due to the significant variation in properties leading to potential mismatch among complexity, regulations and available resources. This symposium will provide a forum for papers exploring the valorization of secondary and byproduct feedstocks including for batteries, electronics, and other complex secondary materials as well as recycling technologies. Those papers providing perspective on both the technical as well as policy-based challenges are encouraged to submit.
