Can't clear "Mekanism: Ore Precessing" quest chapter.

[drowsy veldt]

As said in the tilte, i'm having an issue clearing this chapter.
In fact, i can't get the dirty iron slurry and the clean iron slurry quests, even though i have a full tank in my inventory.
I'm adding screenshots so you can see better

Did you click to see what the quest requirements are ?
