Hi!
I need the mechanism for resolution of racemic 1,2-diaminocyclohexane using L-(+)-tartaric acid.
It's for a report for a student lab we did, but I can't find any information about the mechanism and I've searched journals, textbooks and Google. Any pointers and tips are appreciated!

Not much of a mechanism to be had.  It forms a bis-ammonium salt through simple acid-base chemistry.  The resolution occurs because the two possible salts are diastereomeric and one crystallizes much more readily than the other.
