ALTA 2020 Online was a unique and fantastic event!  Three action packed weeks with 100 presentations, 6 short courses, 3 webinars, 2 social events and a virtual exhibition. Please enjoy the conference report below and we hope to see you all next year at ALTA 2021our 26th annual event.

All opening and keynote videos and papers are now available from the ALTA Free Library and for the first time, panel discussion recordings are available to the industry. Conference proceedings are now available for purchase with immediate download.

ALTA 2020 Online, our 25th anniversary and first online event, attracted a record attendance of 650 participants from 48 countries.  The conference was held over three weeks, from 9-27 November to suit the online format.

It featured one of our best technical programs over the five conferences reflecting the core ALTA focus of innovation.  The five keynote addresses were outstanding with senior industry identities addressing key industry technical topics.  Our trademark panels were better than ever and the three additional short courses were a first-class addition to our program.

We thank each of our opening speakers, keynote speakers and presenters, with a special shout-out to those who participated from other time zones.  We also thank our exhibitors, sponsors, co-sponsors and partners who made the journey with us transitioning to the virtual world, after the postponement of our regular face-to-face conference in May.

A unique benefit of the online format is that the entire event including presentations, papers, short courses, recorded panel discussions and webinars will remain available to new attendees from around the globe until 12 March.  This includes free visitor passes to access recorded webinars and the virtual expo.

The event was opened by Conference Founder and Chair, Alan Taylor, Managing Director and Metallurgical Consultant, ALTA Metallurgical Services, on Tuesday 10 November.


Week One

Week One included our world leading three-day Nickel-Cobalt-Copper Conference, sponsored by Solvay, with 41 presentations and a panel discussion, together with two short courses and three webinars.

The conference commenced with the Opening Address by Dr Jacques Eksteen, Chief Operating Officer and Research Director, Future Battery Industries CRC (Australia), who laid out the research-based strategy for establishing Australia as a leading player in the emerging global battery Industry.  John Neale, Technical Specialist, Mintek (South Africa), followed with the Keynote Address on the progress achieved and future potential of bioleaching of nickel and cobalt.  The on-demand presentation includes the live Q&A session.

Topics for the technical sessions included EV implications; battery precursor products; nickel laterite HPAL operations and projects; developments in alternative laterite processes; heap leaching; nickel-cobalt and copper process innovations; harvesting and processing of deep sea nodules; filtration and dry stacking; ion exchange and solvent extraction; and a final forum with presentations on the hydromet processing of Ni-Co-Cu sulphides.

The conference finale was an hour-long panel discussion and Q&A, chaired by ALTA’s Alan Taylor, on the hydromet processing of Ni-Co-Cu sulphides – an area of increasing industry interest due to the projected demand of the EV and battery industries.  Topics discussed and debated included the increasing role of hydromet processing for producing battery precursor products; challenges for meeting the stringent specifications for battery precursors; potential role for bioleaching for nickel, cobalt and copper; recovery of cobalt from pyritic ores; prospects for new laterite projects given the high capex of currently proven processes; prospects for commercialisation of new laterite processes such as chloride and nitric acid  leaching; deep sea nodules as an alternative source of battery metals; effects of water availability and management on future ore processing; and future uptake of dry stacking.

Week One included two short courses and three webinars, which are available for on-demand viewing until March 2021.

Alan Taylor kicked-off the event with his “A-Z of Copper Ore Leaching” short course which has been presented around the world for many years and is kept current with annual updates.  The “The Art of HPAL - The Way to Success” short course was presented by former Sumitomo executives Dr Naoyuki Tsuchida and Fumio Iwamoto (Japan) and delegates jumped at the opportunity to learn from these knowledgeable presenters.

BASF, long-time ALTA sponsor, presented a webinar for delegates and visitors “Pilot and Full-Scale Trials for BASF LixTRA™ Leaching Aid Reagent”.  JordProxa offered two webinars on “Crystallisation for Battery Chemicals: Chemistry, Purity and Energy Efficiency”: Part 1: Fundamentals of Crystallisation and Part 2: What Makes Lithium Flowsheet Different?


Week Two

The second week featured the Uranium-REE and In-Situ Recovery conferences, with 14 and 16 presentations respectively.  Both conferences included a panel discussion on a key industry topic.  The week’s program also included uranium and SX focused short courses.  The conferences and uranium ore processing short course were organised in cooperation with the International Atomic Energy Agency (IAEA).

Uranium-REE Conference

Martin Fairclough, Uranium Specialist, Uranium Resources and Production, IAEA (Austria) opened the 16th annual ALTA uranium conference with a review of unconventional uranium resources.  Darryl Butcher, Director, BDB Process (Australia), presented the Keynote Address in which he reviewed membrane technology as a process tool, followed by a live Q&A session, now included in the on-demand recording.

Technical sessions covered by-product vanadium recovery; REE processing developments; REE projects; REE processing simulation; REE supply criticality assessment; testing of IX resins; uranium project development; uranium environmental modelling; and a final forum with presentations on the application of membranes to uranium and REE processing.

The forum theme of application of membranes, a potential game-changer for uranium processing, was continued in a one-hour panel discussion with audience Q&A, chaired by ALTA’s Alan Taylor.  Topics addressed included lessons learned from commercial uranium applications; potential for upgrading leach solutions; testwork and scale-up for commercial applications; potential for use in REE processing; clarification of membrane feed solutions; prevention of scale formation and descaling; membrane life and effect on economics; and possible future developments in membrane materials.

In-Situ Recovery Conference

The third annual ALTA ISR Conference, an event co-organised with CSIRO, provides a global focal point for ISR development. The conference was opened with a Keynote Address by Leon Faulkner, Managing Director, EnviroCopper (Australia) on opportunities and challenges for copper ISR using the Kapunda Project under development in South Australia as example.  The live keynote Q&A session is included in the on-demand presentation.

Session topics were permeability enhancement; directional drilling and hydraulic fracturing; application of ISR in hard rock mining, options for underground leach systems; coarse particle leaching amenability tests; ISR project permitting challenges; new ground water monitoring technology; modelling and process optimisation; economic modelling; and a forum with presentations on the application of ISR to copper.

Dr Laura Kuhar, CSIRO Mineral Resources (Australia), chaired the panel discussion on the application of ISR to copper which is becoming the next major target for ISR after uranium.  The agenda covered enabling technologies, approaches and methodologies; priorities to unlock/increase future potential; main challenges to implementation; unconventional applications (e.g. remediation) and crossover of tools from other industries (e.g. oil and gas); economics and permitting; and achieving social licence to operate.
