Prague Seminar 2017

 

General Information

This Seminar took place on the 13 & 14 November 2017, at the Boscolo Hotel in Prague. It was well attended with 137 perticipants - as a matter of fact, the seminar was sold-out more than 1 week before the event!

 

Presentations

Mikhail Khaimov (Mairec) opened the conference with a very attractive title : "General Precious Metals Recycling – the 2nd Oldest Profession in the World. Do we really need innovation?"
Putting customers in the center of the process allows to fullfill their needs, by asking the proper questions - not only "how" and "what", but also "why". With this approach in mind Mairec for example reduced the assaying time from 3 weeks to 3-4 days, which typically answers the customer request for faster feedback and liquidity.

Michelle Lynch (Enabled Future Limited) developped electrification and its impact on PGMs. With forecasts of EV ranging between <10% and >50% of new car sales globally by 2040, it is virtually impossible to plan for future supply chain.
Currently, 60% of PGM consumption is for the automotive industry, Pd being the most exposed to electrification. Over the last 7 years, almost all PGM growth came from that industry, and unfortunately the new usage of PGMs are no "gamechangers".
A shift of feedstock from fossil fuels to CO2 would however significantly reshape the PGM applications. Capturing CO2 is already generating $10 bn in revenue. 

Jonathan Butler (Mitsubishi) came back on an interesting year for palladium - high price increase for investors, tight liquidity for users... A couple of factors explains the rise in palladium price, but nothing really can explain why palladium is currently trading at premium versus platinum.
EFT in Palladium were only established 10 years ago, and all investors are hence currently in position to take profit.
Physical market is so tight that there is currently a net export from Switzerland, while Greater China official gross imports have risen by 9% in the year to date (and consumption having risen much more than that).
Since March 2017, backwardation on the palladium market is observed, with forward price lower than the spot price; this lead to a significant increase in leasing rates. Palladium sponge is at a premium to ingot, a signal of strong industrial demand
The conclusion is that the palladium price is overstreched, although fundamentals are strong.

Shahnawaz Islam (CME). CME was formed by the merging and acquisition of Chicago Mercantile Exchange, Chicago Board of Trade & New York Mercantile Exchange (NYMEX/COMEX). Markets can be accessed almost 24 hours a day.
The role of market regulation was approached - CME for example had their inventories published since several years - and the chain of integrity presented, with approved refiners, approved assayers and approved depositories.

Alexei Kornienko (Krastsmetvet) talked about major impactors on our industry: green chemistry and industry 4.0. This includes a greater environmental and energy-saving awareness, innovation infrastructures and collaborative approaches, as well as digitization of all physical assets.
Eventually, the service will become more important than the product.

 

Federico Padrono Martini (IKOI) made an update on ALS, a pre-refining process removing silver from Au/Ag/Cu feedstocks using vacuum distillation technology. This process is not using any acid nor chemical product, making it by essence a "green" approach to pre-refining.
Typically used for doré material, the largest version of ALS allows to treat as much as 100 kg in one single batch. Latest development, a direct pouring into molds for anodes is possible, singificantly lowering the overall total process time.
 
Denis Borovkov (Plaurum) represents the "local" player through the Czech-based company Safina. Effective technology transfer within the Plaurum group has allowed its expension to new market, as well as growth of low grade waste processing.

 

Klaus Sparn (Umicore) detailed the increasing complexity in autocat recycling. Since Euro 6 implementation, and the addition of NOx aftertreatment and real driving emissions, multiple types of catalysts have been put in the market. They are made of two different substrates, either of SiC or cordierite, and some DPF (Diesel Particulate Filters) are even PGM-free.
The market for SiC-DPF recycling is expected to grow sharply in the next 3-4 years in Europe, eventually contaminating the recycling stream as PGM-free material.
 
Ilya Nekhamin (ReMetall Deutschland) described the advantages of direct current arc smelting, which allows liquification of high-melting point compounds (SiC, ZrO2). Improving classical electrochlorination method used for high SiC content leads to PGM concentrates with >20% of PGM content, while the remaining ceramics contains <50 ppm of PGM.

 

Simona Marta (BASF) followed up on the silicon carbide, and specifically on its analysis.
Due to the potential issues with mixed SiC / cordierite lots, a semi-quantitative method for determining the amount of SiC in recycled autocat lots was developped.
A combinaison of XRF and C gas analysis was put in place, allowing a rapid and cost-effective determination of SiC content.

Bodo Albrecht (Sabin Metal Corp.) gave a very interesting paper on car future for precious metals post internal combustion engine. Several countries have already decided for a ban of gasoline powered cars between 2025 and 2040, including Germany, France & India.
Electric cars represents really a disruptive technology. Tesla car deliveries could follow the Model T production in the early 20th century, with a huge increase of number within an extremely short period.
Lithium, cobalt and rare earths would be the winners of such change, while PGMs are the ony loosers with a -53% consumption.

How could we have a seminar without talking about compliance? Rene Wiskemann (Agosi) described what mined gold should be: coming from registered mines from conflict-free area, without child or forced labor, offering acceptable working conditions and a responsible environmental framework.
Currently, there is a jungle of labels (comprising audited industrial and other audited standards, as well as many company standards): this should not let us lowering our standards.

Following on that topic, Michael Ludwig (ML-SOLUTION) described what is coming in the field of conflict minerals regulations. A new European regulation on 3TG (Tin / Tungsten / Tantalum / Gold) will enter in force in 2021.
While the EU will provide a list of indications of countries concerned, all direct importers will have to complete Due Diligence with their respective suppliers.
