RE:Is the Canadian exchange closed?Yep, it looks like zero volume today in Canada and 150 shares in the U.S. With all the delays, all the potential buyers must have all the shares they want by now. At the same time, anyone who wanted to sell has sold. Everyone is just waiting for some significant news. Getting the gas line hooked up and throwing a party is not the news that investors are waiting for.
Obviously, what we need to know is if this process actually works at full volume throughput.
I was searching ways to dissolve Platinum, and it seems the most common way is using Aqua regia, a mixture of nitric acid and hydrochloric acid. I do not think Regenx is using Aqua regia. Here are some other methods:
- platinum is electrochemically dissolved in a mixture of zinc chloride and a special ionic liquid. An ionic liquid is an organic salt that is in a melted state at temperatures below 100 °C.
- Highly concentrated solutions of AlCl3·6H2O and Al(NO3)3·9H2O were investigated for Au and platinum group metals dissolution. 95% Pd was leached from spent automotive catalysts in 15 min at 80 °C, while Pt required longer times; Rh dissolution was <20%.
- we aimed to recover PGMs via the calcination of spent automotive catalysts (autocatalysts) with Li salts based on the concept of “spent autocatalyst + waste lithium-ion batteries” and leaching with only HCl. The results suggest that, when Li2CO3 was used, the Pt content was fully leached, while 94.9% and 97.5% of Rh and Pd, respectively, were leached using HCl addition.
