Things you should know:

You can only get five Fragmentos de mena iridiscente and one Mena iridiscente per character per week. Resets with the normal weekly reset.
You can only get a certain amount of Fragmentos de mena iridiscente, and the remaining number you can still get for the week can be seen in the profession window when selecting this entry (just called Iridescent Ore) under the section called Appendix I - Boundless Knowledge, it will show as the last line of text on the right. Resets with the normal weekly reset.
All nodes can drop the Fragmentos de mena iridiscente, including elemental nodes, Titan-touched and Infuriated nodes.
Mena iridiscente is essentially the last Fragmentos de mena iridiscente you can get for the week. So when you get the Mena iridiscente, that means you will no longer get any Fragmentos de mena iridiscente or Mena iridiscente on this character for this week.
Primal nodes drop the Piedra cargada por los elementos.
Molten nodes drop the Muestra de mena calentada.
Hardened nodes drop the Trozo de piedra firme.
There appears to be no weekly limit on Piedra cargada por los elementos, Muestra de mena calentada or Trozo de piedra firme, though they have a significantly smaller drop chance compared to Fragmentos de mena iridiscente and likely do not drop from Titan-Touched, Infuriated, Rich and normal nodes.
Piedra cargada por los elementos, Muestra de mena calentada and Trozo de piedra firme all seem to share the same journal entry in the profession window, that being the entry for Piedra cargada por los elementos.

What do you mean? I can't find anything, maybe add a screenshot?

Hello everyone!
Just like stated by EternalWulf, you can check in your tooltip for Fragmentos de mena iridiscente how many you can still gather per week.
However if you would like to have a look for yourself via scripts here they are, along with the Tratado dracónico de minería

/script print(C_QuestLog.IsQuestFlaggedCompleted(72160))
/script print(C_QuestLog.IsQuestFlaggedCompleted(72161))
/script print(C_QuestLog.IsQuestFlaggedCompleted(72162))
/script print(C_QuestLog.IsQuestFlaggedCompleted(72163))
/script print(C_QuestLog.IsQuestFlaggedCompleted(72164))

Mena iridiscente being the last one you can gather for the week.
/script print(C_QuestLog.IsQuestFlaggedCompleted(72165))

As of this post I have maxed mining and am still getting the ore fragments. I now have 2 knowledge points that I cannot spend on any specializations.

EDIT UPDATE: You can now trade the extra knowledge for Entereza de artesano with Aprendiza de artesano or Aprendiza de recolector, who are standing about 20 yards east of the stairs leading up to the crafting orders platform at 37.34, 64.72 in Valdrakken. 10 knowledge for 25 mettle.

An all-in-one macro to check if the following items have been completed for the week:

Tratado dracónico de minería x1
Fragmentos de mena iridiscente x5
Mena iridiscente x1
/run local t={"Crafted",74106,"Blue 1",72160,"Blue 2",72161,"Blue 3",72162,"Blue 4",72163,"Blue 5",72164,"Purple",72165}for i=1,#t-1,2 do print(t,C_QuestLog.IsQuestFlaggedCompleted(t)and "\124cff00ff00Yes" or "\124cffff0000No")end

Items with no weekly limit are the following:

Piedra cargada por los elementos
Trozo de piedra firme
Muestra de mena calentada
