I agree what is your point what methods do you see as being better. Maybe you are saying the only solution you know about is REE Chloride if so explain what you see as advantages over other newer, than traditional SX process.
No they cannot but you can recover all the acid with electrolysis which, I mentioned in my original post, keep reusing the recycled acid. It actually takes less resources to recover acid than make new. The resources is electricity which is not always available. MP is very near some major NG wells so they have plenty of that at low cost. Then just one or two big Turbines and you have lots of electricity and lots of medium temp heat. Both are needed in the REE process. You seem to be stuck in a rut and not able to think outside of the box at all. That box is use HCL instead of sulfuric acid. Not sure of pluses and minuses but you are still using very strong acids for cracking.
Here is some information on both acids. both are nasty in different ways you decide which you would like in your environment. I would prefer to recover and reuse with either one.
https://www.osha.gov/chemicaldata/624https://www.epa.gov/sites/default/files/2016-09/documents/hydrochloric-acid.pdfHere is a detailed paper of making REE Chloride I am sure you can recognize that both a Sulfuric ACID and Hydrochloric ACID process is bad. I will let you decide which you think is worse. To me the disposal problems look about the same.
"The process is chloride based and reagents are recycled, reducing waste generation and optimizing water usage to reduce environmental
impact." they do not go into it much but it is clean because of Recycling JMO this is probably electrolysis. If I am wrong please correct me with some documentation. I have probably not dug into this as much as you.

How much do you think this will change KAL? Do you think Lamp and Texas could both use the same product from KAL? Do you think KAL could switch quickly and cheaply between the two processes?
