Juan had an article up a few weeks back on LinkedIn in Spanish.

He talked about his "Secret Sauce" for the colums. But it was in Spanish and I asked Juan, if he had an English verision. He did not, but asked for my email address and he would send it to me later. So, I did and I received it last week. Here is the last page. I will post a link but I am sure it will go to default.

The operating cycle of the ion exchange equipment, generally comprised of two stages, is as
follows:

Operation === Regeneration

During the operation stage, the resin becomes loaded with impurities (target cations) and this
stage last until the resin is saturated and it is necessary going to the regeneration stage
where its IX capacity is restored.
The regeneration stage has subprocesses which generally are the following:
-Displacement of the solution within the column
-Backwash
-Cleaning of the column with a strong acid
-Displacement of the acid
-Backwash
-Regeneration with sodium hydroxide
-Removal of NaOH
-Washing
After that, the column can resume it operations.
Typically, industrial IX systems work with three columns in tandem (two operationals and one
in reserve). Configuration typically is Lead – Lag columns.
It is quite important to mention that IX equipments must be designed and sized for every
specific project (tailor made) and as we have mentioned in past publications, you cannot
“copy-paste” the equipment from another project or application due to the brines chemical
composition variation between differents salt flats, even brine chemistry could be different in
the same salt flat.
Performing IX in lithium brines, which normally contains 2 to 3 times more sodium than the
sea water, is not simple.
We recommend:
To always perform the laboratory and pilot plant tests to ensure an adecuate design of the IX
systems.
